WEBVTT 1 00:00:00.150 --> 00:00:01.020 In this Lesson, 2 00:00:01.020 --> 00:00:03.390 we're going to talk about removable storage, 3 00:00:03.390 --> 00:00:04.620 now removable storage 4 00:00:04.620 --> 00:00:06.930 really refers to any kind of storage device 5 00:00:06.930 --> 00:00:08.820 that can be moved from computer to computer 6 00:00:08.820 --> 00:00:10.470 without you having to open up the case 7 00:00:10.470 --> 00:00:12.570 and remove it from the inside. 8 00:00:12.570 --> 00:00:14.760 This can also include any kind of storage media 9 00:00:14.760 --> 00:00:17.820 where you can remove the media from inside of the drive, 10 00:00:17.820 --> 00:00:19.470 such as if you have a tape drive 11 00:00:19.470 --> 00:00:22.800 and you pull that tape out after you've done your backups. 12 00:00:22.800 --> 00:00:24.480 So as we move through this lesson, 13 00:00:24.480 --> 00:00:27.750 we're going to talk all about removable mass storage devices 14 00:00:27.750 --> 00:00:30.180 including the different driving closures they use, 15 00:00:30.180 --> 00:00:33.570 flash drives, memory cards, tape drives, 16 00:00:33.570 --> 00:00:36.360 floppy dish drives and things like that. 17 00:00:36.360 --> 00:00:39.330 First, we need to talk about hot swappable. 18 00:00:39.330 --> 00:00:40.410 Now hot swappable 19 00:00:40.410 --> 00:00:42.750 is a term that's really important to understand, 20 00:00:42.750 --> 00:00:46.560 especially when it comes to these removable storage devices. 21 00:00:46.560 --> 00:00:47.393 For example, 22 00:00:47.393 --> 00:00:49.380 if you've ever used an external hard drive 23 00:00:49.380 --> 00:00:50.910 in your laptop or desktop, 24 00:00:50.910 --> 00:00:52.920 and you've plugged it in using USB 25 00:00:52.920 --> 00:00:55.050 and the system automatically recognized the drive 26 00:00:55.050 --> 00:00:56.280 once you connected it, 27 00:00:56.280 --> 00:00:59.610 that is because there's a hot swappable connection there. 28 00:00:59.610 --> 00:01:02.850 Hot swappable drive interfaces include things like USB, 29 00:01:02.850 --> 00:01:04.770 Thunderbolt, and eSATA. 30 00:01:04.770 --> 00:01:07.961 All three of these can support this hot swappable feature. 31 00:01:07.961 --> 00:01:10.830 Now this means that anytime you connect a drive, 32 00:01:10.830 --> 00:01:11.790 your operating system 33 00:01:11.790 --> 00:01:13.800 will automatically recognize the drive. 34 00:01:13.800 --> 00:01:16.920 But in addition to that, you can safely eject that drive 35 00:01:16.920 --> 00:01:19.500 by removing that hardware and then unplugging it 36 00:01:19.500 --> 00:01:21.150 without losing your data. 37 00:01:21.150 --> 00:01:23.640 With a traditional hard drive, you can't do that. 38 00:01:23.640 --> 00:01:25.110 You can't just unplug your SATA 39 00:01:25.110 --> 00:01:27.360 or pay to connector inside of your case 40 00:01:27.360 --> 00:01:29.760 without actually shutting down the computer first 41 00:01:29.760 --> 00:01:31.590 and then safely removing it. 42 00:01:31.590 --> 00:01:33.870 So hot swappable is really important, 43 00:01:33.870 --> 00:01:36.630 especially when we talk about removable storage drives 44 00:01:36.630 --> 00:01:38.100 because it gives us this ability 45 00:01:38.100 --> 00:01:40.530 to add remove additional storage to our system 46 00:01:40.530 --> 00:01:42.450 without having to shut down the entire computer 47 00:01:42.450 --> 00:01:44.430 like we had to do in the old days. 48 00:01:44.430 --> 00:01:45.930 Now, when it comes to SATA, 49 00:01:45.930 --> 00:01:47.340 it's really important to understand 50 00:01:47.340 --> 00:01:49.440 that it does support hot swapping, 51 00:01:49.440 --> 00:01:54.440 but only if you enable AHCI inside of your bios or UEFI. 52 00:01:54.750 --> 00:01:56.640 When I'm talking about AHCI, 53 00:01:56.640 --> 00:01:59.610 I'm talking about the advanced host controller interface, 54 00:01:59.610 --> 00:02:01.080 and this is a technical standard 55 00:02:01.080 --> 00:02:02.490 that was developed by Intel 56 00:02:02.490 --> 00:02:05.280 that allows you to have this hot swappable capability 57 00:02:05.280 --> 00:02:07.410 with SATA devices. 58 00:02:07.410 --> 00:02:11.220 In a lot of systems, AHCI is not enabled by default, 59 00:02:11.220 --> 00:02:14.760 and so by default, SATA usually is not hot swappable 60 00:02:14.760 --> 00:02:16.680 until you go and enable this capability 61 00:02:16.680 --> 00:02:18.930 inside your bios or UEFI. 62 00:02:18.930 --> 00:02:21.480 This is because when SATA was originally developed, 63 00:02:21.480 --> 00:02:23.640 it was developed as replacement for PATA 64 00:02:23.640 --> 00:02:26.250 and it was designed as an internal connector, 65 00:02:26.250 --> 00:02:29.130 but over time, there was an extension made to SATA 66 00:02:29.130 --> 00:02:30.480 called eSATA. 67 00:02:30.480 --> 00:02:33.330 And eSATA simply means external SATA. 68 00:02:33.330 --> 00:02:36.120 And so it's using the exact same cable and connector, 69 00:02:36.120 --> 00:02:37.410 but there's actually a header 70 00:02:37.410 --> 00:02:39.900 that gives you an external SATA port known as eSATA 71 00:02:39.900 --> 00:02:41.430 on the outside of your case. 72 00:02:41.430 --> 00:02:44.040 So you could plug in a hard drive using eSATA 73 00:02:44.040 --> 00:02:46.170 and be able to use this hot swap capability 74 00:02:46.170 --> 00:02:49.830 once you enable AHCI, which is why AHCI was added 75 00:02:49.830 --> 00:02:52.950 as an additional capability for most modern systems. 76 00:02:52.950 --> 00:02:55.290 Now, why would you want to use eSATA? 77 00:02:55.290 --> 00:02:57.390 Well, it has a pretty fast speed, 78 00:02:57.390 --> 00:03:00.060 it's pretty comparable to USB 3.0. 79 00:03:00.060 --> 00:03:01.620 If you're using USB 3.0, 80 00:03:01.620 --> 00:03:05.070 you can get about five gigabits per second with eSATA, 81 00:03:05.070 --> 00:03:06.450 if you're using version two, 82 00:03:06.450 --> 00:03:08.220 you can get three gigabits per second, 83 00:03:08.220 --> 00:03:09.540 and if you're using version three, 84 00:03:09.540 --> 00:03:11.760 you can get up to six gigabits per second. 85 00:03:11.760 --> 00:03:14.010 So for a long time, this was a great way 86 00:03:14.010 --> 00:03:17.157 of providing removable storage at very high speeds. 87 00:03:17.157 --> 00:03:19.740 But with the newest versions of USB, 88 00:03:19.740 --> 00:03:22.200 we can actually get speeds of 10 or 20 89 00:03:22.200 --> 00:03:24.420 or even up to 40 gigabits per second, 90 00:03:24.420 --> 00:03:27.780 making eSATA not as popular as it used to be. 91 00:03:27.780 --> 00:03:30.120 Now, if you've ever used a portable hard drive 92 00:03:30.120 --> 00:03:31.500 or external hard drive, 93 00:03:31.500 --> 00:03:34.500 you may be wondering what actually is inside of that. 94 00:03:34.500 --> 00:03:35.700 What makes it special? 95 00:03:35.700 --> 00:03:37.710 How is it different from the regular hard drive 96 00:03:37.710 --> 00:03:39.240 inside of your computer? 97 00:03:39.240 --> 00:03:42.210 Well, the answer is, it really isn't that different. 98 00:03:42.210 --> 00:03:44.670 Instead, they just take an internal hard drive 99 00:03:44.670 --> 00:03:47.460 and they put it into what's known as a drive enclosure, 100 00:03:47.460 --> 00:03:50.940 which is either made out of steel, metal or plastic. 101 00:03:50.940 --> 00:03:53.340 These drive enclosures simply allow you to take 102 00:03:53.340 --> 00:03:57.450 any kind of internal hard drive, such as a 7,200 RPM, 103 00:03:57.450 --> 00:04:00.300 3.5 inch, eight terabyte hard drive 104 00:04:00.300 --> 00:04:02.190 and put it into the enclosure. 105 00:04:02.190 --> 00:04:03.120 On the enclosure, 106 00:04:03.120 --> 00:04:04.860 there will be a connector on the backside, 107 00:04:04.860 --> 00:04:07.050 generally, this is going to be SATA 3 108 00:04:07.050 --> 00:04:09.330 and it's going to have both data and power connectors. 109 00:04:09.330 --> 00:04:11.070 And then on the outside of the case, 110 00:04:11.070 --> 00:04:12.270 there'll be whatever connector 111 00:04:12.270 --> 00:04:13.830 you're going to use to connect your computer, 112 00:04:13.830 --> 00:04:18.085 which could be eSATA, or more commonly USB or Thunderbolt. 113 00:04:18.085 --> 00:04:20.010 By using this drive enclosure, 114 00:04:20.010 --> 00:04:21.270 we're able to convert the data 115 00:04:21.270 --> 00:04:22.530 from that SATA connection 116 00:04:22.530 --> 00:04:24.270 coming off of the back of the hard drive 117 00:04:24.270 --> 00:04:26.790 into something that is more commonly used on laptops, 118 00:04:26.790 --> 00:04:29.880 desktops and other devices like USB. 119 00:04:29.880 --> 00:04:31.230 So if you go to the store 120 00:04:31.230 --> 00:04:33.390 and you look at all of the external hard drives, 121 00:04:33.390 --> 00:04:36.240 you'll see they come in lots of different shapes and sizes. 122 00:04:36.240 --> 00:04:37.530 There's really large ones 123 00:04:37.530 --> 00:04:39.750 which are using that three and a half inch form factor 124 00:04:39.750 --> 00:04:41.430 inside of a drive enclosure, 125 00:04:41.430 --> 00:04:43.800 while there's others that are using the 2.5 inch 126 00:04:43.800 --> 00:04:47.400 form factor drive inside those portable drive enclosures. 127 00:04:47.400 --> 00:04:48.450 In addition to that, 128 00:04:48.450 --> 00:04:50.970 they also make even smaller ones these days 129 00:04:50.970 --> 00:04:54.690 that rely on SSDs inside of those removable enclosures. 130 00:04:54.690 --> 00:04:58.740 For example, I personally own a one terabyte portable SSD 131 00:04:58.740 --> 00:05:01.830 that connects to my system using a USBC connection 132 00:05:01.830 --> 00:05:04.710 and that is placed inside of an external drive enclosure, 133 00:05:04.710 --> 00:05:06.900 instead of me just carrying around this circuit board 134 00:05:06.900 --> 00:05:08.610 containing the SSD all day, 135 00:05:08.610 --> 00:05:10.530 I have this nice case that holds it 136 00:05:10.530 --> 00:05:12.720 and that is a drive enclosure. 137 00:05:12.720 --> 00:05:14.790 Next let's talk about flash drives 138 00:05:14.790 --> 00:05:17.250 which you normally hear referred to as a USB drive 139 00:05:17.250 --> 00:05:18.600 or a thumb drive. 140 00:05:18.600 --> 00:05:20.580 Now, the reason people call these USB drives 141 00:05:20.580 --> 00:05:22.620 is because most commonly you're going to see these 142 00:05:22.620 --> 00:05:26.250 with a USB connection, but they don't always have to. 143 00:05:26.250 --> 00:05:28.020 I've seen ones that use Thunderbolt, 144 00:05:28.020 --> 00:05:30.840 lightning connectors or other data connectors as well, 145 00:05:30.840 --> 00:05:31.673 but by far, 146 00:05:31.673 --> 00:05:35.190 the most common is the standard USB type-A connector 147 00:05:35.190 --> 00:05:37.770 on the end of one of these thumb drives. 148 00:05:37.770 --> 00:05:39.570 When you're using one of these thumb drives, 149 00:05:39.570 --> 00:05:42.690 it is essentially just a plastic case with a USB connector, 150 00:05:42.690 --> 00:05:44.280 and on the inside of that case, 151 00:05:44.280 --> 00:05:46.650 you will find these circuits or chips 152 00:05:46.650 --> 00:05:48.690 that essentially are like the SSDs 153 00:05:48.690 --> 00:05:50.940 that we use in modern drives. 154 00:05:50.940 --> 00:05:52.980 In general, I find that these thumb drives 155 00:05:52.980 --> 00:05:56.070 do use a lower quality than a standard SSD would 156 00:05:56.070 --> 00:05:57.630 giving them less performance. 157 00:05:57.630 --> 00:05:59.700 But overall they're still pretty fast 158 00:05:59.700 --> 00:06:01.320 and they work really well. 159 00:06:01.320 --> 00:06:03.570 The great thing about these flash drives or thumb drives 160 00:06:03.570 --> 00:06:06.480 as we like to call them is that they are small and portable 161 00:06:06.480 --> 00:06:09.060 and they come in lots of different shapes and sizes. 162 00:06:09.060 --> 00:06:11.580 For example, I had one on my key chain before 163 00:06:11.580 --> 00:06:13.410 that was just a little bit larger 164 00:06:13.410 --> 00:06:15.810 than a standard USB type-A port. 165 00:06:15.810 --> 00:06:17.460 This was extremely small 166 00:06:17.460 --> 00:06:19.860 and yet it could still hold 64 gigabytes 167 00:06:19.860 --> 00:06:22.410 of data on that drive, making it very small 168 00:06:22.410 --> 00:06:25.200 and portable to carry with me anywhere I was going. 169 00:06:25.200 --> 00:06:27.510 And that's really the big benefit of these flash drives 170 00:06:27.510 --> 00:06:29.400 is you could take them anywhere with you 171 00:06:29.400 --> 00:06:33.210 because they are so small and they can hold a lot of data. 172 00:06:33.210 --> 00:06:35.730 Now the next thing we need to talk about is memory cards. 173 00:06:35.730 --> 00:06:38.370 Now memory cards are simply a different form factor 174 00:06:38.370 --> 00:06:40.920 that's going to be used in different types of products, 175 00:06:40.920 --> 00:06:44.640 such as video cameras, digital cameras, smartphones, 176 00:06:44.640 --> 00:06:48.120 tablets, wearables, and IoT devices. 177 00:06:48.120 --> 00:06:50.940 There are numerous formats of memory cards out there 178 00:06:50.940 --> 00:06:55.940 but the most common is SD, MiniSD, MicroSD, CompactFlash, 179 00:06:56.190 --> 00:06:57.540 and memory stick. 180 00:06:57.540 --> 00:06:59.790 Memory Stick is a proprietary protocol 181 00:06:59.790 --> 00:07:01.440 that's used on Sony devices, 182 00:07:01.440 --> 00:07:03.000 whereas the others are all used 183 00:07:03.000 --> 00:07:05.942 across a variety of different manufacturers in the field. 184 00:07:05.942 --> 00:07:08.400 In order to read or write to a memory card, 185 00:07:08.400 --> 00:07:11.580 you need to have a memory card reader on your system. 186 00:07:11.580 --> 00:07:12.690 Some computers have these 187 00:07:12.690 --> 00:07:14.430 built into the front of their case, 188 00:07:14.430 --> 00:07:16.920 while others will use an external memory card reader 189 00:07:16.920 --> 00:07:19.350 that connects to your system using USB. 190 00:07:19.350 --> 00:07:21.390 For example, on my laptop, 191 00:07:21.390 --> 00:07:24.900 it has an SD card reader built right into the system. 192 00:07:24.900 --> 00:07:26.340 But if I wanted to read something 193 00:07:26.340 --> 00:07:29.670 like a memory stick from Sony or a compact flashcard, 194 00:07:29.670 --> 00:07:31.350 I would have to use an external reader 195 00:07:31.350 --> 00:07:34.170 connected through USB or USBC. 196 00:07:34.170 --> 00:07:35.003 These days, 197 00:07:35.003 --> 00:07:38.040 you're going to find memory cards in all different sizes, 198 00:07:38.040 --> 00:07:41.730 in the old days, the original SD or secure digital cards 199 00:07:41.730 --> 00:07:45.210 had a maximum capacity of about two gigabytes in size. 200 00:07:45.210 --> 00:07:46.230 But these days, 201 00:07:46.230 --> 00:07:49.770 you can get an SDHC card that goes up to 32 gigabytes 202 00:07:49.770 --> 00:07:53.580 or an SDXC card that goes up to two terabytes in size. 203 00:07:53.580 --> 00:07:57.420 Currently, as I'm recording this video, I'm using an SDXE 204 00:07:57.420 --> 00:08:00.900 which is a 256 gigabyte secure digital card 205 00:08:00.900 --> 00:08:02.970 that stores the recording for me. 206 00:08:02.970 --> 00:08:04.560 Now, when you're looking at these cards, 207 00:08:04.560 --> 00:08:06.930 they can operate at vastly different speeds. 208 00:08:06.930 --> 00:08:08.820 So it's important to look at the speed rating 209 00:08:08.820 --> 00:08:10.470 when you're buying a card. 210 00:08:10.470 --> 00:08:13.050 These can go up to 25 megabytes per second 211 00:08:13.050 --> 00:08:14.820 with the original specification 212 00:08:14.820 --> 00:08:18.360 or up to 108 megabytes per second using UHS, 213 00:08:18.360 --> 00:08:19.980 if you're using UHS-2, 214 00:08:19.980 --> 00:08:23.190 this can have speeds of up to 312 megabytes per second, 215 00:08:23.190 --> 00:08:26.400 and if you're using a UHS-3, you can actually have a speed 216 00:08:26.400 --> 00:08:30.060 of up to 624 megabytes per second. 217 00:08:30.060 --> 00:08:33.660 So depending on your application, you may need a faster card 218 00:08:33.660 --> 00:08:35.880 to be able to handle that application. 219 00:08:35.880 --> 00:08:38.730 For example, if you're doing full 4K video 220 00:08:38.730 --> 00:08:40.530 and recording that to a video camera, 221 00:08:40.530 --> 00:08:41.580 you're probably going to need something 222 00:08:41.580 --> 00:08:43.920 like a UHS-3 specification, 223 00:08:43.920 --> 00:08:47.220 which operates at up to 624 megabytes per second 224 00:08:47.220 --> 00:08:50.310 because you're trying to store so much data at one time. 225 00:08:50.310 --> 00:08:51.300 Whereas on the other hand, 226 00:08:51.300 --> 00:08:53.520 if you're just using a simple voice recorder, 227 00:08:53.520 --> 00:08:54.353 you can get away 228 00:08:54.353 --> 00:08:57.720 with the original specification of 25 megabytes per second 229 00:08:57.720 --> 00:08:59.370 because most voice recordings 230 00:08:59.370 --> 00:09:02.460 are only operating at about half a megabyte per second 231 00:09:02.460 --> 00:09:04.740 and therefore 25 megabytes per second 232 00:09:04.740 --> 00:09:07.380 is plenty fast for that use case. 233 00:09:07.380 --> 00:09:09.990 The next thing we're going to talk about is tape drives. 234 00:09:09.990 --> 00:09:12.300 Now, most of you are not going to use tape drives 235 00:09:12.300 --> 00:09:15.570 in your home environment, but if you work in a corporation 236 00:09:15.570 --> 00:09:16.950 and you're working on servers, 237 00:09:16.950 --> 00:09:19.290 most of them are going to be using tape drives, 238 00:09:19.290 --> 00:09:21.060 and tape drives are a great example 239 00:09:21.060 --> 00:09:23.160 of a removable storage device. 240 00:09:23.160 --> 00:09:24.210 Now in recent years, 241 00:09:24.210 --> 00:09:27.540 tape drives are losing popularity to cloud-based backups, 242 00:09:27.540 --> 00:09:28.980 but you are still going to see this 243 00:09:28.980 --> 00:09:32.580 in a wide variety of applications out there in the field. 244 00:09:32.580 --> 00:09:33.990 When you look at a tape drive, 245 00:09:33.990 --> 00:09:36.750 it uses a magnetic tape inside of a plastic case 246 00:09:36.750 --> 00:09:38.310 that we placed into a reader, 247 00:09:38.310 --> 00:09:40.170 and you'll be able to copy a backup 248 00:09:40.170 --> 00:09:42.960 of the data of your system onto that tape. 249 00:09:42.960 --> 00:09:45.390 The great thing about these tapes is you can then take them 250 00:09:45.390 --> 00:09:47.610 and ship them off to another facility, 251 00:09:47.610 --> 00:09:50.940 and that way you can have offsite backup of your data. 252 00:09:50.940 --> 00:09:53.430 For example, I used to be the IT director 253 00:09:53.430 --> 00:09:56.160 for a large network and security operation center, 254 00:09:56.160 --> 00:09:57.180 and every evening 255 00:09:57.180 --> 00:09:59.910 we would do a backup of our systems to a tape. 256 00:09:59.910 --> 00:10:02.550 Then at the end of the week, we would take all the tapes 257 00:10:02.550 --> 00:10:04.650 and we would ship them to our backup facility, 258 00:10:04.650 --> 00:10:07.050 and that way, if our main facility burned down 259 00:10:07.050 --> 00:10:08.400 or had a catastrophe, 260 00:10:08.400 --> 00:10:10.470 we would still have all of our data safe and sound 261 00:10:10.470 --> 00:10:11.940 at the other site. 262 00:10:11.940 --> 00:10:13.770 Now, as I said, a lot of companies 263 00:10:13.770 --> 00:10:16.260 have moved to the cloud for their backups instead of tapes, 264 00:10:16.260 --> 00:10:19.110 but tape backups is still something used widely 265 00:10:19.110 --> 00:10:21.090 in government and military organizations. 266 00:10:21.090 --> 00:10:22.980 So I wanted you to be aware of it. 267 00:10:22.980 --> 00:10:24.360 When it comes to a tape, 268 00:10:24.360 --> 00:10:26.880 each tape can store a certain amount of data. 269 00:10:26.880 --> 00:10:28.290 If you're using a standard tape, 270 00:10:28.290 --> 00:10:31.590 these usually will hold about 140 gigabytes of data. 271 00:10:31.590 --> 00:10:33.690 Whereas the LTO Ultrium tapes 272 00:10:33.690 --> 00:10:36.720 can hold up to three terabytes on a single tape. 273 00:10:36.720 --> 00:10:38.550 That amount of capacity is usually enough 274 00:10:38.550 --> 00:10:41.310 to be able to back up most systems, but if not, 275 00:10:41.310 --> 00:10:43.500 your system can span multiple tapes 276 00:10:43.500 --> 00:10:46.530 and you can keep going until you get the entire backup done, 277 00:10:46.530 --> 00:10:50.430 even if it becomes a set of three, five or even 50 tapes 278 00:10:50.430 --> 00:10:52.170 to get a complete backup. 279 00:10:52.170 --> 00:10:54.750 The final type of removal storage device I want to talk about 280 00:10:54.750 --> 00:10:57.090 in this lesson is floppy drives. 281 00:10:57.090 --> 00:10:59.430 Now floppy drives are a really old 282 00:10:59.430 --> 00:11:01.560 and legacy way of storing data 283 00:11:01.560 --> 00:11:03.570 that you would take out of your system. 284 00:11:03.570 --> 00:11:06.000 This was around before we had USB thumb drives, 285 00:11:06.000 --> 00:11:08.220 this was around before we had SSDs, 286 00:11:08.220 --> 00:11:12.030 this was around back in the 1970s, 80s, and 90s. 287 00:11:12.030 --> 00:11:13.530 And honestly, most people today 288 00:11:13.530 --> 00:11:15.510 are not going to be using a floppy drive 289 00:11:15.510 --> 00:11:17.670 unless they're working on a specific system 290 00:11:17.670 --> 00:11:19.320 in a legacy environment. 291 00:11:19.320 --> 00:11:20.790 For example, if you're working 292 00:11:20.790 --> 00:11:22.770 with some ICS and SCADA systems 293 00:11:22.770 --> 00:11:24.870 or you're working with some military hardware, 294 00:11:24.870 --> 00:11:28.020 some of those still rely on floppy discs to get their data. 295 00:11:28.020 --> 00:11:29.970 And so I wanted to make you aware of it. 296 00:11:29.970 --> 00:11:33.060 If you look at the save icon in any application these days, 297 00:11:33.060 --> 00:11:34.530 that is a floppy disc, 298 00:11:34.530 --> 00:11:38.220 and technically, that is called a 3.5 inch floppy disc. 299 00:11:38.220 --> 00:11:39.270 That is what we used to save 300 00:11:39.270 --> 00:11:41.070 all of our documents on in school, 301 00:11:41.070 --> 00:11:42.930 and we would be able to take it home with us 302 00:11:42.930 --> 00:11:45.990 instead of using a USB drive like we do today. 303 00:11:45.990 --> 00:11:48.390 Now those drives can't hold much data. 304 00:11:48.390 --> 00:11:51.390 In fact, a standard floppy disc can only handle 305 00:11:51.390 --> 00:11:55.440 1.44 megabytes of data on it, which is not even 306 00:11:55.440 --> 00:11:58.230 really one picture today taken by your iPhone. 307 00:11:58.230 --> 00:12:00.780 So it really isn't going to be able to hold a lot of data 308 00:12:00.780 --> 00:12:01.613 but like I said, 309 00:12:01.613 --> 00:12:04.800 it is used in some of these older legacy systems. 310 00:12:04.800 --> 00:12:06.420 If you're working with a legacy system 311 00:12:06.420 --> 00:12:08.850 and you need to be able to get access to a floppy disc drive 312 00:12:08.850 --> 00:12:10.560 and your computer doesn't have one, 313 00:12:10.560 --> 00:12:12.780 you can buy external floppy disc drives 314 00:12:12.780 --> 00:12:14.280 using a USB connection 315 00:12:14.280 --> 00:12:16.200 to be able to connect it to a modern system, 316 00:12:16.200 --> 00:12:18.150 because the original floppy disc drives 317 00:12:18.150 --> 00:12:21.270 actually connected with a 34 bit internal IDE 318 00:12:21.270 --> 00:12:22.410 or PATA cable 319 00:12:22.410 --> 00:12:24.930 and required a Berg power cable to connect to it 320 00:12:24.930 --> 00:12:25.920 and give it power. 321 00:12:25.920 --> 00:12:28.410 The problem is I haven't seen a modern motherboard 322 00:12:28.410 --> 00:12:29.850 in at least the last 10 years 323 00:12:29.850 --> 00:12:32.340 that provided that type of connection to the motherboard. 324 00:12:32.340 --> 00:12:33.690 And this is why there are 325 00:12:33.690 --> 00:12:36.420 external USB floppy drives available for sale 326 00:12:36.420 --> 00:12:38.010 if you have one of these use cases 327 00:12:38.010 --> 00:12:40.200 where you're going to have to use a floppy disc. 328 00:12:40.200 --> 00:12:42.420 All right, I know that was a ton of information 329 00:12:42.420 --> 00:12:44.190 when it comes to removable storage 330 00:12:44.190 --> 00:12:46.680 but I want you to remember a couple of key things, 331 00:12:46.680 --> 00:12:49.920 first, when it comes to removable mass storage devices, 332 00:12:49.920 --> 00:12:51.720 this means any type of device 333 00:12:51.720 --> 00:12:54.210 that you can put data on and take with you. 334 00:12:54.210 --> 00:12:56.700 That's going to include things like external hard drives, 335 00:12:56.700 --> 00:12:59.640 USB thumb drives, memory cards, backup tapes 336 00:12:59.640 --> 00:13:00.990 and floppy discs. 337 00:13:00.990 --> 00:13:04.077 In addition to optical discs like CDs, DVDs 338 00:13:04.077 --> 00:13:05.340 and Blueray discs 339 00:13:05.340 --> 00:13:07.830 but we'll talk more about those in their own lesson. 340 00:13:07.830 --> 00:13:08.940 And the other thing to remember 341 00:13:08.940 --> 00:13:12.030 is if you're using an external hard drive or SSD, 342 00:13:12.030 --> 00:13:13.590 these are actually the same type 343 00:13:13.590 --> 00:13:15.540 that are going to be used inside your system. 344 00:13:15.540 --> 00:13:18.120 The only difference is they're placed into a drive enclosure 345 00:13:18.120 --> 00:13:19.770 that converts their data port 346 00:13:19.770 --> 00:13:22.170 into something that's usable as an external interface 347 00:13:22.170 --> 00:13:25.200 that's hot swappable, like USB, Thunderbolt 348 00:13:25.200 --> 00:13:26.763 or an eSATA connection.
