1 00:00:06,600 --> 00:00:11,600 - SATA is very common in today's PCs and laptops. 2 00:00:12,240 --> 00:00:14,760 The serial AT attachment, 3 00:00:14,760 --> 00:00:16,140 or SATA, 4 00:00:16,140 --> 00:00:19,500 or sata or sada, however you wanna say it, 5 00:00:19,500 --> 00:00:24,500 is a computer bus that's used for the transmission of data 6 00:00:24,600 --> 00:00:29,400 between hard drives and the motherboard or an adapter card. 7 00:00:29,400 --> 00:00:33,274 It allows for data transfer rates or DTRs 8 00:00:33,274 --> 00:00:38,274 between 1.5 gigabits per second and 16 gigabits per second 9 00:00:39,360 --> 00:00:42,753 depending on the revision of SATA. 10 00:00:44,550 --> 00:00:48,600 Traditional SATA uses two cables, 11 00:00:48,600 --> 00:00:51,120 data and power. 12 00:00:51,120 --> 00:00:55,800 Data connectivity is accomplished with a 7-pin cable 13 00:00:55,800 --> 00:01:00,450 which supplies the drive with two pairs of conductors 14 00:01:00,450 --> 00:01:02,400 that work in a serial fashion, 15 00:01:02,400 --> 00:01:05,313 meaning one bit at a time each. 16 00:01:06,780 --> 00:01:10,410 Power is supplied by a 15-pin cable 17 00:01:10,410 --> 00:01:15,410 that includes 3.3 volts, 5 volts, and 12 volts. 18 00:01:16,500 --> 00:01:21,210 Keep in mind that some SATA power cables are color coded. 19 00:01:21,210 --> 00:01:24,360 They're orange, red, and yellow or they simply use 20 00:01:24,360 --> 00:01:27,120 all one color such as black, 21 00:01:27,120 --> 00:01:30,123 including the two black grounding wires. 22 00:01:31,680 --> 00:01:35,661 So this is a typical setup with a 3.5 inch 23 00:01:35,661 --> 00:01:40,080 magnetic based drive, a mechanical drive with moving parts, 24 00:01:40,080 --> 00:01:41,350 and you have that 25 00:01:42,870 --> 00:01:46,230 power port and the data ports 26 00:01:46,230 --> 00:01:48,573 and you use these connectors for those. 27 00:01:51,000 --> 00:01:56,000 Now here we have a 2.5 inch solid state drive, also SATA. 28 00:01:56,610 --> 00:02:00,270 So it has the same types of connectors, 7-pin data 29 00:02:00,270 --> 00:02:05,010 and 15-pin power and they have vertical tabs in the center 30 00:02:05,010 --> 00:02:07,860 so that you know how to orient the cables 31 00:02:07,860 --> 00:02:08,973 when you connect them. 32 00:02:11,010 --> 00:02:16,010 Let's take a look at the SATA revisions over time. 33 00:02:16,500 --> 00:02:20,550 And so first we have SATA Revision 1.0 34 00:02:20,550 --> 00:02:22,380 which has a maximum data transfer rate 35 00:02:22,380 --> 00:02:27,380 of 1.5 gigabytes per second, or 150 megabytes per second. 36 00:02:29,301 --> 00:02:34,301 2.0 did 3 gigabytes per second, or 300 megabytes per second, 37 00:02:35,220 --> 00:02:37,500 but it's unlikely that you'll see either of those 38 00:02:37,500 --> 00:02:39,660 unless it's a pretty old system, 39 00:02:39,660 --> 00:02:41,917 because in 2009, 40 00:02:41,917 --> 00:02:46,200 SATA Revision 3.0 was released, 41 00:02:46,200 --> 00:02:48,990 and so it's been around for at least a decade, 42 00:02:48,990 --> 00:02:51,300 depending on when you're watching this video, 43 00:02:51,300 --> 00:02:54,570 and that allows for 6 gigabytes per second 44 00:02:54,570 --> 00:02:57,540 or 600 megabytes per second. 45 00:02:57,540 --> 00:02:59,910 Now you may say, "Hey, I was dividing by eight 46 00:02:59,910 --> 00:03:02,430 and the math doesn't really work out for me" 47 00:03:02,430 --> 00:03:05,460 and that's because of encoding. 48 00:03:05,460 --> 00:03:07,650 There's actually a little bit of overhead 49 00:03:07,650 --> 00:03:11,370 and this 6 gigabits per second over the connection 50 00:03:11,370 --> 00:03:15,720 actually goes down to about 4.8 gigabits per seconds. 51 00:03:15,720 --> 00:03:18,480 Divide that by eight and then you actually get 52 00:03:18,480 --> 00:03:23,253 600 megabytes per second to the drive maximum. 53 00:03:24,477 --> 00:03:27,390 This is very common as far as SATA goes, 54 00:03:27,390 --> 00:03:29,340 that's the most common that you're gonna see, 55 00:03:29,340 --> 00:03:32,180 but there's also SATA Revision 3.2. 56 00:03:33,104 --> 00:03:37,650 3.2 uses SATA Express, 57 00:03:37,650 --> 00:03:42,650 which can work on an SATA express port, 58 00:03:42,660 --> 00:03:47,660 or it can work within an M.2 configuration or even USB 3.0. 59 00:03:50,250 --> 00:03:52,980 But if you're using M.2 60 00:03:52,980 --> 00:03:55,920 and NVMe, 61 00:03:55,920 --> 00:04:00,660 PCIe-based card will usually be preferred 62 00:04:00,660 --> 00:04:03,120 because it allows for higher data transfer rates. 63 00:04:03,120 --> 00:04:05,097 While this sata 3.2 64 00:04:06,411 --> 00:04:11,411 and SATA Express can do just about two gigabytes per second, 65 00:04:11,670 --> 00:04:15,030 a lot of the NVMe M.2 cards 66 00:04:15,030 --> 00:04:17,220 can go much further than that, they can go up to about 67 00:04:17,220 --> 00:04:22,220 3,500 megabytes per second or 3.5 gigabytes per second. 68 00:04:22,680 --> 00:04:24,330 So these are the two you really wanna know. 69 00:04:24,330 --> 00:04:26,760 3.0 you're gonna see a lot, but you might also see 70 00:04:26,760 --> 00:04:31,760 3.2 out there and the 3.0 port that's used, looks like that. 71 00:04:33,210 --> 00:04:36,900 That is the data port. That's your standard 7-pin port, 72 00:04:36,900 --> 00:04:39,240 similar, and it's basically what we showed before, 73 00:04:39,240 --> 00:04:42,420 this is just looking head on into that port. 74 00:04:42,420 --> 00:04:44,700 That's two of these ports, actually. 75 00:04:44,700 --> 00:04:48,363 3.2 uses a sort of a triple port. 76 00:04:49,740 --> 00:04:54,740 It's three in one and this is known as an 18-pin port. 77 00:04:54,930 --> 00:04:58,500 It's 7 + 7 + 4 78 00:04:58,500 --> 00:05:00,690 and it's one cable that is kind of 79 00:05:00,690 --> 00:05:03,243 three connectors in one that connects to this. 80 00:05:04,461 --> 00:05:07,830 So a little difference there and you need to have that 81 00:05:07,830 --> 00:05:10,350 on the motherboard or on an adapter card to actually 82 00:05:10,350 --> 00:05:13,740 take advantage of SATA Express, or again, like I say 83 00:05:13,740 --> 00:05:17,490 M.2 or USB 3.0, but again, for higher speeds 84 00:05:17,490 --> 00:05:19,800 people are usually going in different directions. 85 00:05:19,800 --> 00:05:24,800 They might be using an M.2 NVMe card currently. 86 00:05:25,770 --> 00:05:29,760 Okay? So a little bit about the SATA revisions. 87 00:05:29,760 --> 00:05:31,050 Definitely wanna memorize it, 88 00:05:31,050 --> 00:05:36,050 commit the SATA 3.0 and 3.2 revisions, 89 00:05:36,300 --> 00:05:41,250 their data transfer rates and the port types to your memory. 90 00:05:41,250 --> 00:05:43,000 So there's a little bit about SATA.
