WEBVTT 00:00:00.020 --> 00:00:04.460 this is speed 00:00:05.460 --> 00:00:12.620 Gen 4 more like Jen snore gen 5. I feel 00:00:10.440 --> 00:00:20.939 alive this PCIe Gen 5 SSD May well be the 00:00:17.520 --> 00:00:24.180 fastest m.2 drive on the planet over 12 00:00:20.939 --> 00:00:26.160 gigabytes a second that is so fast you 00:00:24.180 --> 00:00:31.380 could move your Warzone install in about five seconds and even if you're more 00:00:29.340 --> 00:00:34.920 into playing games than copy pasting them around with direct storage 00:00:32.940 --> 00:00:41.100 compatible titles finally hitting the market Gamers might have a reason to add 00:00:38.040 --> 00:00:43.379 storage speed to their list of specs 00:00:41.100 --> 00:00:50.100 that actually matter let's see what this thing can do wait a minute 00:00:46.680 --> 00:00:52.379 69 megabytes a second that's not nice 00:00:50.100 --> 00:00:56.699 that's not nice at all just like it's not nice to make you wait 00:00:54.420 --> 00:01:00.899 and find out what's going on after this message from our sponsor thanks to the 00:00:59.039

purchase and get free shipping 00:01:15.479 --> 00:01:22.680 before we get into the inconvenient details let's talk about what makes the 00:01:19.320 --> 00:01:25.619 crucial t700 a hair among tortoises a 00:01:22.680 --> 00:01:32.280 star among planets a diamond among roughs it starts with the interface 00:01:28.860 --> 00:01:34.140 while this may look exactly like the 00:01:32.280 --> 00:01:38.460 kind of m.2 drive that you would install in your PC and in fact you could since 00:01:36.659 --> 00:01:43.560 it's fully backwards compatible when paired with a PCIe Gen 5 capable CPU and 00:01:41.460 --> 00:01:50.759 motherboard it goes from a theoretical maximum of 7.9 gigabytes a second to 00:01:46.979 --> 00:01:53.579 nearly 16 gigabytes a second but Linus 00:01:50.759 --> 00:01:58.979 you might say even your best case scenario demo you did had it anywhere 00:01:55.740 --> 00:02:02.220 from 11 to 12 gigabytes a second uh well 00:01:58.979 --> 00:02:04.439 yes while the interface itself can hit 00:02:02.220 --> 00:02:09.000 the speeds I just said this is our big but wait there's less moment you see 00:02:07.439 --> 00:02:14.280 there's more than one factor that affects the real world performance of an 00:02:10.920 --> 00:02:17.340 SSD and the interface is one of them but 00:02:14.280 --> 00:02:20.340 another is the controller and our t700 00:02:17.340 --> 00:02:23.099 here has a doozy of a controller the new 00:02:20.340 --> 00:02:27.599 fizen e26 is an eight channel controller that can easily handle drives with four 00:02:25.140 --> 00:02:33.120 terabytes of capacity at speeds of up to 14 gigabytes per second that is nearly 00:02:30.599 --> 00:02:38.940 double the speed of their end game Gen 4 controller 00:02:34.620 --> 00:02:41.459 I know 14 gigabytes a second is also not 00:02:38.940 --> 00:02:47.340 12 but you're forgetting the third major factor that affects SSD performance The 00:02:44.580 --> 00:02:52.319 nand Flash that actually stores the data and this is the hardest part to scale 00:02:49.819 --> 00:02:58.860 honestly the fact that this thing is as fast as it is is a modern Miracle the 00:02:54.780 --> 00:03:01.440 t700 uses micron's latest 232 layer TLC 00:02:58.860 --> 00:03:05.819 nand at 2 000 Mega transfers per second to deliver the performance we saw up to 00:03:03.959 --> 00:03:10.260 12 plus gigabytes per second of sequential reads and about 11 gigabytes 00:03:08.340 --> 00:03:15.180 per second of sequential rights in both the 2 and 4 terabyte capacities now 00:03:12.900 --> 00:03:20.280 curiously it seems that by pushing the dies to their full rated 2400 Mega 00:03:18.239 --> 00:03:24.659 transfers per second they could probably saturate the fize and e26 controller but 00:03:23.159 --> 00:03:29.040 there are some reasons that they might not do that starting with that it 00:03:26.700 --> 00:03:35.580 probably wouldn't affect anything behind me is two identical ryzen 7950x bench 00:03:33.000 --> 00:03:43.019 PCS courtesy of our lab on the left we've got the Samsung 990 Pro probably 00:03:39.060 --> 00:03:45.900 the fastest Gen 4 SSD on the market if 00:03:43.019 --> 00:03:51.780 you ignore the firmware issues on the right we've got the t700 Gen 5 baby uh 00:03:50.340 --> 00:03:56.400 time for our Crystal dismark drag race let's go okay your your team your team 00:03:54.000 --> 00:04:00.360 last year gen gen four gen four wait how many of these t700 tradition versus 00:03:58.080 --> 00:04:06.540 modernity this is great all right we ready yeah let's go let's go let's go 00:04:03.900 --> 00:04:10.080 didn't even count in what why I went okay it was already around now yeah I 00:04:08.819 --> 00:04:14.760 want to win what can I say oh look at this see you 00:04:12.900 --> 00:04:19.680 later buddy how's my rearview mirror treating you oh my God this is brutal 00:04:16.799 --> 00:04:23.880 literally more than double double the performance 00:04:20.880 --> 00:04:25.259 we're back to sequentials let's go right 00:04:23.880 --> 00:04:28.860 speed baby particularly those lower Q depth 00:04:27.360 --> 00:04:36.419 sequentials just crushing the Gen 4 Drive 00:04:33.060 --> 00:04:39.300 uh that's my first L if you look closely 00:04:36.419 --> 00:04:44.400 you'll notice the weak improvements in random reads and random writes which 00:04:41.880 --> 00:04:49.320 funnily enough is the category of Drive activity that represents typical 00:04:46.139 --> 00:04:52.320 day-to-day use and it's also where most 00:04:49.320 --> 00:04:54.660 drives struggle why is that so slow 00:04:52.320 --> 00:04:58.740 well here's the thing writing to an SSD is kind of like boarding an airplane 00:04:56.220 --> 00:05:04.199 each row is a block and if you want to add a person to a row well first you 00:05:02.100 --> 00:05:08.340 need to pull everyone out of that row so the new person can get in then everyone 00:05:06.120 --> 00:05:12.900 has to sit back down this takes time with sequential rights people ready to 00:05:11.040 --> 00:05:17.940 be seated together in convenient groups of three you can fill several rows or 00:05:15.300 --> 00:05:21.240 blocks quickly but with random rights you've got different people trickling in 00:05:19.800 --> 00:05:24.660 and out of different sections at different times and they all got to 00:05:22.860 --> 00:05:28.440 squeeze into the various random open seats on the plane sequential rights are 00:05:27.000 --> 00:05:32.160 also slowed down when there are people already sitting in a row but when 00:05:30.660 --> 00:05:35.160 there's some down time the flight attendants are running the trim function 00:05:33.840 --> 00:05:38.820 where they move people who have been seated in their own rows into rows with 00:05:37.020 --> 00:05:42.479 other people so that when an influx of new passengers come along we don't have 00:05:40.740 --> 00:05:47.880 to worry as much about doing the awkward seat dance when those random rights do 00:05:45.240 --> 00:05:51.600 happen though boy does it ever suck here we go Adam let's go oh we're doing what 00:05:49.979 --> 00:05:54.900 are we doing now we want we are opening some programs oh let's see let's open 00:05:53.580 --> 00:06:02.120 some programs okay so we should close steam let's close steam yeah launch Team 00:05:57.720 --> 00:06:02.120 okay three two one go 00:06:04.320 --> 00:06:11.280 okay that was this same same even the 00:06:07.320 --> 00:06:14.460 ads lived at the same uh uh uh Edge 00:06:11.280 --> 00:06:17.100 three two one go 00:06:14.460 --> 00:06:22.440 um maybe something heavier uh like a game maybe closed Edge okay PC Mark's 00:06:19.919 --> 00:06:25.580 kind of a dog yeah open up PC mark one two three go 00:06:28.500 --> 00:06:38.100 oh whoa that was a pretty big win actually significant yeah okay but can 00:06:34.020 --> 00:06:42.900 we repeat it three two one go 00:06:38.100 --> 00:06:46.380 uh uh okay now on the subject of PC mark 00:06:42.900 --> 00:06:48.060 it did in the storage Benchmark show a 00:06:46.380 --> 00:06:53.460 solid win for the new drive with the t700 leading by about 16 but in less 00:06:51.479 --> 00:06:59.039 good news when we fired up for spoken which at this point is our only PC 00:06:56.160 --> 00:07:01.919 showcase for direct storage um it was just plain couldn't tell the 00:07:01.080 --> 00:07:09.180 difference that's not to say we couldn't measure the difference we were looking at about 00:07:06.180 --> 00:07:12.060 a five percent Advantage for our Gen 5 00:07:09.180 --> 00:07:17.699 SSD but there was no difference in actual frame rate and that five percent 00:07:15.419 --> 00:07:23.400 was just not something we could actually notice in Final Fantasy end Walker we 00:07:21.060 --> 00:07:28.979 did see a 14 Improvement in load times which is cool but it's a far cry from 00:07:26.940 --> 00:07:32.580 the 40 Improvement that these drives showed in synthetic benchmarks like 00:07:31.020 --> 00:07:37.199 Crystal disk marks you know what maybe we should just do a 00:07:35.400 --> 00:07:40.740 big file transfer in Windows I mean we say it all the time you know these 00:07:39.060 --> 00:07:44.819 sequential drives at least they're good for big file transfers let's do some big 00:07:42.720 --> 00:07:51.060 files all right yeah this is going to go really fast probably so 00:07:47.880 --> 00:07:53.099 six gigabytes a second five gigabytes a 00:07:51.060 --> 00:07:57.860 second four and a half gigabytes a second I mean 00:07:55.259 --> 00:08:03.960 that's pretty fast 4.2 gigabytes a second but that's that's 00:08:01.500 --> 00:08:09.599 really fast maybe the fastest I've ever seen we seem to have hit some sort of 00:08:06.960 --> 00:08:14.880 file explorer or bottleneck here at about four gigabytes a second 00:08:11.940 --> 00:08:18.780 but here's the thing even if Windows Explorer didn't come up against its own 00:08:16.680 --> 00:08:24.300 software limitations when performance is this fast it can only last for so long 00:08:21.300 --> 00:08:27.120 running our new drives in iometer free 00:08:24.300 --> 00:08:31.139 of Windows File Explorer we've slammed them for 15 minutes of continuous 00:08:28.979 --> 00:08:36.180 activity and saw our speeds fall precipitously in less than a minute down 00:08:33.599 --> 00:08:40.500 to about three gigabytes a second what's going on here you might ask is it 00:08:38.039 --> 00:08:43.740 thermal throttling the answer is no with either the heatsink on the drive or the 00:08:42.539 --> 00:08:48.180 integrated heat spreader on your motherboard these drives stay well 00:08:45.600 --> 00:08:52.800 within their thermal limits what did happen though is we overwhelmed the cash 00:08:50.220 --> 00:08:57.959 on our Drive pretty much all modern drives store more than one bit per cell 00:08:55.260 --> 00:09:02.399 which gives them more capacity but comes at the cost of performance and Longevity 00:09:00.180 --> 00:09:07.680 but here's the thing many drives especially performance ones can operate 00:09:04.860 --> 00:09:12.839 that multi-bit per cell nand in a kind of pseudo SLC mode so it's kind of like 00:09:10.800 --> 00:09:17.519 switching over a segment of the storage to go much faster but at the cost of 00:09:15.480 --> 00:09:22.620 capacity once the drive has filled up that low capacity cache it starts 00:09:19.620 --> 00:09:25.620 running at much slower TLC Nan speeds 00:09:22.620 --> 00:09:27.720 then when that is nearly full we move to 00:09:25.620 --> 00:09:32.399 what's called a folding state where the drive runs at a distinctly unimpressive 00:09:29.880 --> 00:09:37.320 one to one and a half gigabytes per second basically it's bottlenecked by 00:09:35.339 --> 00:09:40.440 being forced to rearrange data on the Fly while it's operating rather than 00:09:39.300 --> 00:09:46.440 being allowed to perform these operations in the background while you aren't using it which if you remember 00:09:43.320 --> 00:09:49.740 from our airplane analogy is pretty 00:09:46.440 --> 00:09:52.620 inefficient lo and behold the 990 Pro 00:09:49.740 --> 00:09:57.480 suffers the exact same fate even coming in at similar sustained numbers wait a 00:09:54.899 --> 00:10:03.120 second that's because despite the impressively dense new nand on the t700 00:10:00.019 --> 00:10:05.760 it's not actually faster than the nand 00:10:03.120 --> 00:10:10.740 flash from Top tier Gen 4 drives like the 990 Pro bummer 00:10:08.279 --> 00:10:15.420 to be clear this only happens when you're moving incredibly large files and 00:10:12.899 --> 00:10:19.500 it doesn't reflect typical use most of the time you're doing those random reads 00:10:17.459 --> 00:10:24.600 and writes that can easily be handled by the high speed cache which is actually 00:10:22.620 --> 00:10:28.860 an even bigger problem for the marketing teams who are tasked with selling these 00:10:26.339 --> 00:10:34.800 drives if the sequential numbers aren't sustainable and the Gen 5 interface is 00:10:32.220 --> 00:10:37.680 ludicrously overkill for the more random workloads that we encounter on a daily 00:10:36.300 --> 00:10:42.899 basis what is the point of this thing okay 00:10:40.260 --> 00:10:47.160 it's possible that you're a power user with numerous virtual machines or Docker 00:10:45.480 --> 00:10:51.839 containers you could have some use for this but honestly I think even that is 00:10:50.220 --> 00:10:58.440 kind of missing the point of what makes PCIe Gen 5 drives so exciting the real 00:10:56.160 --> 00:11:04.260 exciting part is not necessarily this drive or even the current PCIe gen 5 00:11:01.260 --> 00:11:05.820 crop of platforms but rather The 00:11:04.260 --> 00:11:10.980 increased expansion that could be available to us in the future 00:11:07.860 --> 00:11:13.500 thanks to gen 5's faster per Lane data 00:11:10.980 --> 00:11:20.279 rates we could in theory get the same performance from our drives as last gen 00:11:15.720 --> 00:11:23.220 or gpus or network cards using half as 00:11:20.279 --> 00:11:28.320 many lanes like think about a ryzen 5000 system you got your GPU that 16 lanes 00:11:25.980 --> 00:11:31.740 you've got your single m.2 storage drive that's another four and then you're 00:11:30.240 --> 00:11:34.620 sitting there going hmm I need more storage why don't I add a second m.2 00:11:33.839 --> 00:11:40.680 Drive well when you go to add that second Drive instead of running off the PCIe 00:11:38.820 --> 00:11:43.980 lanes that are directly wired into the CPU you're going to be running off lanes 00:11:42.779 --> 00:11:49.440 that are going through the motherboard chipset which is fine but the more 00:11:47.519 --> 00:11:52.980 drives you want to add the more potential there's going to be for 00:11:50.880 --> 00:11:58.740 bottlenecks unless you want to fall back to slower SATA drives now workstation 00:11:56.100 --> 00:12:04.200 class CPUs do exist with much greater PCIe connectivity but they're also 00:12:01.620 --> 00:12:08.579 significantly more expensive with PCIe Gen 5 on the other hand well we get 00:12:06.720 --> 00:12:14.459 double the performance with the same number of lanes or the same performance 00:12:11.279 --> 00:12:16.860 using half as many lanes so suddenly you 00:12:14.459 --> 00:12:21.660 could have two drives out of more than ample eight gigabytes a second with nice 00:12:19.380 --> 00:12:25.800 low latency connections directly to the CPU personally I'd actually like to see 00:12:24.120 --> 00:12:30.720 us go all the way down to a single Lane Drive at four gigabytes a second and 00:12:27.779 --> 00:12:35.700 then I could have four of them sick now in practice it's not that simple 00:12:33.300 --> 00:12:39.360 nothing ever is but think about it this could be a very interesting path for the 00:12:37.500 --> 00:12:44.339 industry to follow and in fact we're already seeing it in the server space 00:12:40.920 --> 00:12:46.320 now you might be wondering why not just 00:12:44.339 --> 00:12:50.639 make more Lanes instead of trying to make the lanes faster well the thing is 00:12:48.120 --> 00:12:54.600 that more Lanes means more pins are needed to connect them and more pins 00:12:52.560 --> 00:12:59.639 means more complexity and more complexity means higher costs so while 00:12:58.139 --> 00:13:04.860 I'm a little disappointed to find out that there is no clear benefit to this 00:13:01.500 --> 00:13:06.899 thing for the average gamer hey at least 00:13:04.860 --> 00:13:11.279 we can have fun with them right see big numbers uh why don't we raid zero these 00:13:09.360 --> 00:13:15.899 drives see how fast they go hey hey raid zero is a valid 00:13:13.440 --> 00:13:20.760 configuration David oh my God are you actually using Windows Drive manager to 00:13:18.300 --> 00:13:23.760 really use storage space just do it I don't care we just got to get this guy 00:13:22.320 --> 00:13:28.139 in here this is ridiculous well there's two in here now you're booted on we have 00:13:26.459 --> 00:13:32.760 to format it into a drive and then are these hot spots uh PCIe is not hot 00:13:30.420 --> 00:13:37.019 chocolate yes it is it is well not on consumer platforms I'm shutting it down 00:13:35.399 --> 00:13:43.680 how many of these can you fit in there in the tech I thought you were gonna ask how many I could fit in my butt oh I was 00:13:41.339 --> 00:13:48.000 gonna ask about your Tech sack did you try this and it's really fast 00:13:45.300 --> 00:13:52.920 yes neat well it failed when I tried to create it so that's cool 00:13:50.940 --> 00:13:56.220 um and just like if we were running a single Drive 00:13:54.660 -->
