all right guys I promised ages ago some
0:04
monster results with this LSI 9280 8i
0:09
raid card and if you're a student enough you'll be able to see in the background
0:14
of the card itself you can see I've got the battery backup unit here as well as
0:18
the uh the key that gives me access to their fast path fast path feature which
0:23
is optimizing for ssds as well as cash Cade which uses ssds to optimize the
0:28
performance of your hard drive array so I promised you monster numbers I have
0:32
finally come through sorry it's taken so long to get this together but there you
0:37
have it when you raid together eight ocz
0:42
vertex 2 60 gig drives they are capable
0:45
of achieving 1.3 gab per second read
0:50
that's a sequential read so it's not all that indicative of performance but it's
0:55
still quite impressive now bear in mind I did promise you guys uh more than
0:59
anything else more than 1 GB pers second read speeds so that's what I have
1:03
optimized all of my RAID settings for you can see are eight identical ocz
1:08
vertex 2 drives here and they are running very randomly off of the
1:13
controller here so I've got these long cables just running all over the place
1:17
but uh yeah bear in mind like I said I
1:20
could be optimizing for certain other uh other performance but what I've really
1:25
gone for here is massive sequential reads and uh it has finally been
1:30
achieved so just for comparison one of these ssds alone is capable of about
1:35
260 g megabytes per second read actually
1:38
hold on let me just uh find that 285 285
1:43
so you pair together or throw together eight and we're really reaching the
1:48
maximum of what a raid card like this can provide which is actually one of the
1:52
best raid cards on the market in terms of SSD performance so if you were using
1:56
a lesser raid card uh or in fact okay why don't we start with onboard raid if
2:00
you're using onboard raid that is i1r the RAID controller built into your
2:03
Intel motherboard you're going to cap out around 600 mb per so adding a
2:09
high-end dedicated controller like this Nets you as you can see much better
2:14
performance so it doesn't matter how many you hook up past about three you're
2:17
not going to get any additional scaling whereas with this particular card we can
2:21
keep going all the way up to the maximum number of connectors we have and we
2:25
continue to get better performance now some other raid cards will scale again
2:30
better than onboard but not quite this well so this is one of the best examples
2:34
uh big thanks to LSI for helping us do this little uh demonstration of what we
2:39
can have in the future if storage technology keeps going the way that it
2:44
is very impressive
