So guys, this is the moment I am finally
0:03
testing my 9260 8i RAID card with a configuration that I
0:08
think can make it reach an internal bottleneck.
0:14
Holy crow, look at that. So I have taken my
0:19
dual Elmrest configuration and I have
0:23
doubled it. So, I'm running four Intel
0:26
SSD 510 series 120 GB drives in RAID
0:31
zero using a 128 kilo kilo bit 128k
0:36
stripe and all of the other options that I
0:40
found to be quite optimal. So, here you can actually see my results with two
0:44
drives and uh these are my preliminary
0:47
results with a single drive. Focus please. Come on, focus. You can focus.
0:53
There you go. Okay, so I'm running five tests at 4 gigs across my 445 gig drive,
1:01
which is those four drives in RAID zero. And it looks like we're looking at about
1:06
1.5 megabytes per second read. And that
1:09
seems to be hitting an internal bottleneck on the RAID card itself. And
1:14
then for rights, you can see the rights are just monstrous. So the rights are
1:19
actually still scaling from two drives to four drives almost exactly double. So
1:25
we're looking at almost 1 Gigabyte per second sequential write speeds to these
1:31
four Intel 510 series drives. So I'm going to just wait for the rest of the
1:35
test to finish and then I'll show you guys the final results.
1:40
Okay, so I finished running Crystal Disc Mark as well as PC Mark Vantage. So you
1:46
can see here the suite has finished running. So on the left I have the four
1:51
drive array. You can see that random performance doesn't scale uh especially
1:55
on the right side quite as well as the sequential performance. On the right, I
2:00
have dual drives on the onboard controller because really the only
2:05
reason to run a third-party controller on a P67 motherboard would be
2:12
if you want to run more than two 6 GB per second SSD drives in RAID zero. So
2:17
based on testing two drives on this controller, the 9260 against two drives
2:21
on the onboard, performance was very similar. So, we're looking at whether
2:26
you would get any benefit from going to four drives from two drives using a
2:31
third party controller, which you would need to do because no P67 motherboard
2:35
supports more than two SATA 36 GB per second drives in RAID zero. So, here
2:41
you've got the Crystal Disc Mark performance numbers. And here the PC
2:45
Mark Vantage numbers are a bit of a mystery. So, I'll just show you the
2:51
actual scores here. So hold on, let me just try and remember
2:56
which is which. Yeah, here we go. So here's the onboard rate where we have 66
3:00
megs per second in as the No, that's the
3:05
PC mark score. Yeah, 66,644
3:10
hard drive PC mark score. Whereas with the four drive RAID zero, we have 58,537
3:17
PC mark score. All right. So, the onboard RAID zero with two drives
3:20
actually scores better overall than the four drive RAID zero array. But
3:25
we don't really understand why that is until we go a little bit deeper into the
3:28
results. So, you can see here, actually, why don't I put these side by
3:34
side so you can compare them more easily.
3:37
Yeah, that'll do.
3:40
Okay. Okay, so at the bottom we have our RAID zero or rather on the left we have
3:44
our RAID zero with four drives and on the right we have our RAID zero on the
3:48
onboard controller with two drives. So you can see the four drive RAID zero
3:52
array cleanly beats the onboard two
3:56
drive array which it should so it should in everything but video editing using
4:00
Windows Live Movie Maker and Windows Media Center where this one destroys it.
4:06
So, this looks like it's actually skewing the results overall because you
4:10
can see as you get further down, adding music, uh, application loading, things
4:14
like uh, antivirus, these all score dramatically better on the four drive
4:19
RAID zero array. So, I'm going to pull out one more result here using my handy
4:24
dandy mark reader, and that is going to
4:27
be the two drives on the RAID controller
4:33
rather than on the onboard. So you can see that the score is actually quite
4:38
similar. Look at that. So it looks like our performance doesn't scale that much
4:44
with the add-in RAID controller, the LSI
4:47
controller by adding more drives. So there you have it. It looks like two
4:52
drives is about all that we are able to leverage with PC Mark Vantage. I mean
4:56
you can see the scores do improve a little bit. This is four drives. This is
4:59
two drives, but that's pretty much it. So, thanks guys for checking out this
