WEBVTT 00:00:00.160 --> 00:00:07.440 okay so today's video yeah it's a product that really makes no sense to me at least on the 00:00:07.440 --> 00:00:13.440 surface this right here is i've actually got the product page up behind me this is come come on 00:00:13.440 --> 00:00:18.400 come on come on get in here check this out check this out this is the i don't know highland star 00:00:18.400 --> 00:00:27.440 micro electronica anyway we ordered it from usb.brando.com and this doodad right here adapts 00:00:27.440 --> 00:00:35.600 as regular SATA interface with some controller from sage that i've never heard of to 10 micro sd 00:00:35.600 --> 00:00:51.860 slots that's quality right there so yes my friends today we're going to make our own SSD today's 00:00:51.860 --> 00:00:57.220 video is brought to you by tunnelbear the simple vpn try tunnelbear for free at tunnelbear.com 00:00:57.780 --> 00:01:04.980 LTT we're going to have that linked below so step one is going to be some r-ing t effing m because 00:01:06.180 --> 00:01:06.580 while 00:01:06.660 --> 00:01:14.340 it does seem fairly straightforward in principle you take the 10 micro sd cards that kingston 00:01:14.340 --> 00:01:20.340 graciously sent you because you're a famous youtuber and then you install them in all the 00:01:20.340 --> 00:01:27.460 things i do want to make sure that we are doing it correctly so instructional note number the first 00:01:27.460 --> 00:01:35.380 you can use one two four eight or oh my goodness 10 micro sd cards at one time it does not support 00:01:35.380 --> 00:01:36.260 three five seven 00:01:36.660 --> 00:01:45.060 or nine instructional step number the second insert the micro sd cards into the micro sd slots 00:01:45.060 --> 00:01:55.220 one by one as the order shown on adapter where is chp0l i just see con tf1 tf6 tf2 i think that's 00:01:55.220 --> 00:02:05.760 for trans flash why does this pcb say demo on it okay well we're just gonna we're just gonna go 00:02:07.360 --> 00:02:13.730 where's here's tf1 let's do this thing am i doing this right you put it down and then you slide it 00:02:13.730 --> 00:02:22.210 there we go so the idea here is that it runs all of your micro sd cards which aside from being a 00:02:22.210 --> 00:02:29.170 much lower grade typically than the nan flash that you would find in an SSD are fundamentally the 00:02:29.170 --> 00:02:35.970 same thing it runs them all in raid zero to make up for the fact that a typical micro sd card 00:02:35.970 --> 00:02:37.690 will be capable of anywhere from 10 to 20 micro sd cards so i'm just going to make sure that i'm not 00:02:37.690 --> 00:02:45.050 from, you know, 20 to maybe 80 to 90 megabytes a second reads and writes, whereas a typical SSD, 00:02:45.490 --> 00:02:52.570 especially a SATA 3 one, can saturate a SATA 3 interface at around, you know, 550 or so megabytes 00:02:52.570 --> 00:02:58.800 per second. One problem that I do foresee, though, is that there's more to life than sequential 00:02:58.800 --> 00:03:05.080 performance when it comes to SSDs, and the controller dictates what the random performance 00:03:05.080 --> 00:03:12.000 will be like. And, oh, that too ignores the other problem, which is that the flash on a typical 00:03:12.000 --> 00:03:18.840 microSD card is not only slower, but also less resilient than the higher quality stuff on a 00:03:18.840 --> 00:03:23.860 normal SSD. A problem that is compounded, this is all about the problems with this thing, hey, 00:03:24.340 --> 00:03:30.960 compounded by the fact that you're running this whole thing in RAID 0. So one dead microSD card 00:03:30.960 --> 00:03:35.800 means, poof, there goes your data. It's gone. 00:03:36.700 --> 00:03:49.320 So there it is. For better or for worse, this is now a 1.2 terabyte RAID 0 microSD SATA SSD. I 00:03:49.320 --> 00:03:56.380 don't know what it is. Let's plug it in. This is so dumb. It's like, cool, but it's like, why? 00:03:56.380 --> 00:04:06.430 There it is. No way. 1.16 terabytes of usable space. 00:04:06.870 --> 00:04:15.720 Let's call this drive letter K, because it's special. So I'm actually a bit of a loss now, 00:04:15.780 --> 00:04:20.640 because I'm going to let you guys behind the curtain for a second here. While I was prepping 00:04:20.640 --> 00:04:28.320 this video, I actually realized that this probably wasn't going to work, because I hadn't gone 00:04:28.320 --> 00:04:35.920 through the instructions ahead of time, and I just noticed that it says right here, do not support 00:04:38.280 --> 00:04:49.390 and these are quite clearly UHS-I cards. So I was expecting to like go on a field trip to Best Buy 00:04:49.390 --> 00:04:58.810 and come back. But it's working. So let's let's test it, I guess. Okay, so if I told you we have 00:04:58.810 --> 00:05:08.360 the world's stupidest SSD, special K drive here, how would you benchmark it? It's 10 microSD cards 00:05:08.360 --> 00:05:09.160 on a PCB. 00:05:09.520 --> 00:05:11.340 We could use Chris. 00:05:11.340 --> 00:05:14.080 We could use CrystalDiskBrack, we could use Atto. 00:05:14.080 --> 00:05:22.540 Yes. I'm coming into this with literally no expectations whatsoever. Actually, at 512 byte, 00:05:22.540 --> 00:05:26.600 that's not even that bad, is it? This is at a queue depth of eight, though. So to be clear, 00:05:26.680 --> 00:05:32.340 this is very unrealistic for a desktop workload. Okay, so there's a couple of takeaways here. 00:05:32.420 --> 00:05:39.740 Number one is that our drive is indeed SATA 2. And number two is that the performance is actually 00:05:39.740 --> 00:05:41.320 better than I thought. 00:05:41.340 --> 00:05:46.960 Unexpected. But this is just sequential. This doesn't really tell us anything about how it would 00:05:46.960 --> 00:05:53.140 perform in a real world workload. Let's hit it with CrystalDiskBrack just for lulz. Oh, wow. 00:05:54.560 --> 00:05:59.540 We're still going to run the passmark test, I guess, but this is not looking good for random 00:05:59.540 --> 00:06:06.500 performance. This is performing about like you'd expect from a bad SSD four or five years ago, 00:06:06.500 --> 00:06:10.140 because there's a lot more to SSD performance than just 00:06:10.140 --> 00:06:11.100 taking a... 00:06:11.400 --> 00:06:20.400 A bunch of NAND flash and writing to and reading from it in a parallelized manner to get more speed 00:06:20.400 --> 00:06:28.000 out of it. The controller intelligence has to be high in order to get better. Oh, wow. These random 00:06:28.000 --> 00:06:30.060 numbers, these are awful. 00:06:30.060 --> 00:06:40.540 Okay. So for our last trick, passmark disk thread test. So the average latency here doesn't really 00:06:40.540 --> 00:06:41.680 tell us the whole story. 00:06:42.100 --> 00:06:44.740 So here's the thing. The thing that just really impacts the performance of a drive 00:06:44.740 --> 00:06:47.840 is the speed or speed of it. You can see, it's a little picture-ish, but you really feel the 00:06:47.840 --> 00:06:55.180 slowness of a drive is when it spikes. That's what most modern SSDs are really trying to overcome, 00:06:55.180 --> 00:06:58.440 is those spikes in latencies. That's when you click on something and you feel like your computer's 00:06:58.440 --> 00:07:07.140 like . So we are seeing spikes up to almost half a second on this drive, with a lot of them 00:07:07.140 --> 00:07:09.600 actually sitting here around a fifth of a second. 00:07:09.600 --> 00:07:10.450 So... 00:07:10.450 --> 00:07:11.450 While you could... 00:07:11.450 --> 00:07:12.170 Run an OS on this thing, 00:07:12.170 --> 00:07:12.290 So... while you could... 00:07:12.290 --> 00:07:17.140 really wouldn't recommend it and to drive that point home I've actually 00:07:17.140 --> 00:07:23.480 spent the last half an hour waiting for Windows to install off a USB drive and 00:07:23.480 --> 00:07:28.500 it's still at 81% of getting files ready for installation this thing is kind of 00:07:28.500 --> 00:07:32.220 painfully slow like to the point where I'm having a really hard time figuring 00:07:32.220 --> 00:07:36.860 out what its purpose could possibly be because you might go oh well you know 00:07:36.860 --> 00:07:41.800 maybe disposable data that you need to be faster than a hard drive but not as 00:07:41.800 --> 00:07:46.300 fast as an SSD like a Steam game library but even then the cost is so 00:07:46.300 --> 00:07:52.420 high to fill this thing with 64 gig or 128 gig micro SD cards like we did would 00:07:52.420 --> 00:07:58.600 cost more than just buying a proper SSD like a Crucial MX 500 or a WD blue so 00:07:58.600 --> 00:08:10.420 I'm not sure why it exists but it does and it's cool so there it is and you 00:08:10.420 --> 00:08:14.580 know what else is cool Dollar Shave Club if you haven't for whatever reason sign 00:08:14.580 --> 00:08:19.080 up for Dollar Shave Club then now is a better time than ever for just five 00:08:19.080 --> 00:08:24.060 bucks they are offering their shave shower starter set it includes their 00:08:24.060 --> 00:08:28.020 executive razor as well as three trial sized versions of some of their most 00:08:28.020 --> 00:08:33.200 popular products their body wash their shave butter and their one wipe Charlie's 00:08:33.200 --> 00:08:37.080 butt wipes after the starter set replacement cartridges are just a few 00:08:37.080 --> 00:08:40.740 bucks a month so head over to dollarshaveclub.com slash Linus we're 00:08:40.740 --> 00:08:44.580 gonna have that link below and join the club so thanks for watching guys if you 00:08:44.580 --> 00:08:47.340 just like this video you can hit that button but if you liked it hit like get 00:08:47.340 --> 00:08:50.520 subscribed maybe consider checking out where to buy the maybe not that this 00:08:50.520 --> 00:08:54.240 thing but maybe the SD cards and and that site actually where we got this has 00:08:54.240 --> 00:08:57.340 lots of other cool random gadgets as well so you can check that out at the 00:08:57.340 --> 00:09:00.540 link in the video description also link down there is our merch store which has 00:09:00.540 --> 00:09:03.900 cool shirts like this one and our community forum which you should totally 00:09:03.900 --> 00:09:06.380 join
