00:00:00.520 --> 00:00:09.120
all right guys I promised ages ago some

00:00:04.759 --> 00:00:12.000
monster results with this LSI 9280 8i

00:00:09.120 --> 00:00:15.759
raid card and if you're a student enough you'll be able to see in the background

00:00:14.200 --> 00:00:20.560
of the card itself you can see I've got the battery backup unit here as well as

00:00:18.480 --> 00:00:25.800
the uh the key that gives me access to their fast path fast path feature which

00:00:23.119 --> 00:00:30.279
is optimizing for ssds as well as cash Cade which uses ssds to optimize the

00:00:28.359 --> 00:00:35.200
performance of your hard drive array so I promised you monster numbers I have

00:00:32.840 --> 00:00:42.399
finally come through sorry it's taken so long to get this together but there you

00:00:37.960 --> 00:00:45.600
have it when you raid together eight ocz

00:00:42.399 --> 00:00:50.920
vertex 2 60 gig drives they are capable

00:00:45.600 --> 00:00:53.160
of achieving 1.3 gab per second read

00:00:50.920 --> 00:00:57.440
that's a sequential read so it's not all that indicative of performance but it's

00:00:55.000 --> 00:01:01.840
still quite impressive now bear in mind I did promise you guys uh more than

00:00:59.559 --> 00:01:05.560
anything else more than 1 GB pers second read speeds so that's what I have

00:01:03.680 --> 00:01:11.240
optimized all of my RAID settings for you can see are eight identical ocz

00:01:08.759 --> 00:01:14.960
vertex 2 drives here and they are running very randomly off of the

00:01:13.240 --> 00:01:20.720
controller here so I've got these long cables just running all over the place

00:01:17.560 --> 00:01:23.560
but uh yeah bear in mind like I said I

00:01:20.720 --> 00:01:27.720
could be optimizing for certain other uh other performance but what I've really

00:01:25.560 --> 00:01:32.439
gone for here is massive sequential reads and uh it has finally been

00:01:30.119 --> 00:01:38.840
achieved so just for comparison one of these ssds alone is capable of about

00:01:35.560 --> 00:01:43.280
260 g megabytes per second read actually

00:01:38.840 --> 00:01:45.880
hold on let me just uh find that 285 285

00:01:43.280 --> 00:01:49.880
so you pair together or throw together eight and we're really reaching the

00:01:48.040 --> 00:01:54.320
maximum of what a raid card like this can provide which is actually one of the

00:01:52.040 --> 00:01:58.640
best raid cards on the market in terms of SSD performance so if you were using

00:01:56.119 --> 00:02:02.560
a lesser raid card uh or in fact okay why don't we start with onboard raid if

00:02:00.280 --> 00:02:05.880
you're using onboard raid that is i1r the RAID controller built into your

00:02:03.920 --> 00:02:11.959
Intel motherboard you're going to cap out around 600 mb per so adding a

00:02:09.200 --> 00:02:15.599
high-end dedicated controller like this Nets you as you can see much better

00:02:14.040 --> 00:02:19.560
performance so it doesn't matter how many you hook up past about three you're

00:02:17.480 --> 00:02:23.720
not going to get any additional scaling whereas with this particular card we can

00:02:21.519 --> 00:02:27.319
keep going all the way up to the maximum number of connectors we have and we

00:02:25.200 --> 00:02:31.879
continue to get better performance now some other raid cards will scale again

00:02:30.040 --> 00:02:36.720
better than onboard but not quite this well so this is one of the best examples

00:02:34.360 --> 00:02:42.280
uh big thanks to LSI for helping us do this little uh demonstration of what we

00:02:39.400 --> 00:02:46.760
can have in the future if storage technology keeps going the way that it

00:02:44.400 --> 00:02:49.760
is very impressive
