00:00:05.799 --> 00:00:12.040
adata xpg V2 memory kits are optimized for the latest Intel gaming platforms

00:00:10.599 --> 00:00:16.440
check the link in the video description for more details now we all know ssds

00:00:14.519 --> 00:00:21.519
are pretty much the ultimate in terms of performance on a desktop system for your

00:00:18.520 --> 00:00:26.160
storage but what many of you probably actually do know is that you can run

00:00:23.240 --> 00:00:31.279
multiple ssds together in raid zero kind of like SLI for ssds to get even better

00:00:29.279 --> 00:00:37.760
performance out of of them particularly in sequential read and write operations

00:00:34.120 --> 00:00:39.960
now it doesn't much like SLI it doesn't

00:00:37.760 --> 00:00:44.800
necessarily scale perfectly it's like if you run 16 ssds in a system will it

00:00:42.120 --> 00:00:51.360
perform 16 times better the answer is no but without getting into expensive fancy

00:00:48.800 --> 00:00:57.079
Hardware raid cards or other Exotic Solutions we wanted to find out where

00:00:53.559 --> 00:01:00.239
exactly is the limit in scaling for ssds

00:00:57.079 --> 00:01:02.960
running on a regular Intel Desktop PC we

00:01:00.239 --> 00:01:07.680
this platform because it has six SATA 36 GB per second ports running off of the

00:01:04.839 --> 00:01:12.799
Intel chipset the last generation z77 only had two so it was really hard to do

00:01:10.400 --> 00:01:16.560
this kind of an investigative thing so we decided to run four different

00:01:14.840 --> 00:01:21.520
configurations by the way big thanks to adata for providing these sx900 sand

00:01:18.920 --> 00:01:27.079
Force based ssds for our test we ran single drive two drive three drive and

00:01:25.280 --> 00:01:30.159
four Drive I lost the last box I have no idea where it is so don't worry trust me

00:01:28.880 --> 00:01:35.280
we definitely ran four Drive drives they're all there um and we wanted to

00:01:32.520 --> 00:01:39.680
see where the differences in performance really start well disappearing so to

00:01:38.040 --> 00:01:43.759
speak so we ran three different benchmarks we ran PC Mark Vantage so we

00:01:41.960 --> 00:01:48.880
ran the storage subsystem test and what you'll see here is that it becomes quite

00:01:46.640 --> 00:01:53.119
clear very quickly that just because you double the theoretical performance of

00:01:50.840 --> 00:01:56.439
one aspect of your system doesn't mean that you're necessarily going to double

00:01:54.600 --> 00:02:01.759
the real world performance because PC Mark is more of a real world oriented

00:01:58.960 --> 00:02:05.799
test we also Alo see that that small performance difference even continues to

00:02:04.159 --> 00:02:09.920
diminish as we add more and more drives giving us that sort of well aderes to

00:02:08.319 --> 00:02:13.480
the law of diminishing returns just like you'd see with adding more channels to

00:02:11.400 --> 00:02:17.760
memory operation or adding more graphics cards to an SLI or Crossfire config now

00:02:16.080 --> 00:02:21.519
when we move on to a synthetic test we ran both reads and right speeds using

00:02:19.760 --> 00:02:25.720
the black magic disc speed test which we found to be quite repeatable and quite

00:02:23.519 --> 00:02:30.720
realistic in terms of theoretical maximums you'll see that once again we

00:02:27.840 --> 00:02:35.519
see a very clear doubling of performance going from a single drive to a two Drive

00:02:33.280 --> 00:02:40.280
configuration but once we get into these multi-drive configs three drives still

00:02:38.160 --> 00:02:45.519
scales extremely well but adding a fourth drive really doesn't do a whole

00:02:42.360 --> 00:02:47.680
lot for even theoretical performance so

00:02:45.519 --> 00:02:54.000
while you'll still get extra capacity when you run four 256 gig ssds in raate

00:02:51.440 --> 00:02:58.560
zero you get effectively 1 terab of capacity you won't necessarily continue

00:02:56.480 --> 00:03:04.120
to get a speed Improvement and you should also be aware that every time you

00:03:00.480 --> 00:03:06.280
add another SSD you are adding to the

00:03:04.120 --> 00:03:12.120
points of failure that exist in your system and increasing the risk that just

00:03:09.080 --> 00:03:14.000
by a single Drive failing you will lose

00:03:12.120 --> 00:03:18.920
all of your data if you aren't doing very regular backups so thank you for
