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