then","speaker":null,"is_sponsor":0},{"start_s":260.919,"end_s":269.12,"text":"this one here is with two drives so this is with four drives so you can see from","speaker":null,"is_sponsor":0},{"start_s":266.36,"end_s":275.28,"text":"2 to four did not scale nearly as well so back to to two up to four did

sequential","speaker":null,"is_sponsor":0},{"start_s":307.36,"end_s":313.6,"text":"right so that's where we're seeing just just huge improvements and then

to do a video update when I had a chance to run the eight ocz Onyx Series ssds in raid zero so you can see I've got these hooked up to an LSI Mega raade fast path SSD optimized RAID controller and uh what fast path does is it actually allows ssds to perform a little bit better so fast path is just the little uh the little key that I have on there it also enables some Advanced encryption features as well as the ability to use ssds as a cache for a hard drive uh rate array so that's a this is a pretty cool card this is the 9260 and it's uh it's actually a SAS I did an unboxing of it it's a SAS 6 gbit per second card but as you can see it's obviously compatible with uh SATA 2 ssds I shouldn't even call it SATA 2 what I mean to say is SATA 3 GB per second so here I'll show you actually here why don't we take this video as an opportunity to show you how easy it is to set up a RAID controller card uh in a raid zero configuration so first of all I want to show you some benchmarks here you can see that with this array we were able to achieve uh almost 700 megabytes per second read which honestly shouldn't be that impressive this card is capable of well over 1 GB per second read with the right ssds so that I was actually a little bit disappointed in but the right speeds are very impressive the right scale scaled almost linearly on these ssds so we were able to achieve up to 450 mb per on rights so I'll show you what I mean by all of this in just a moment here um this is kind of interesting I wasn't having any challenges with the uh with the raid configuration before or you know what I think it is well looks like you get to uh see some real time troubleshooting here I think we've just got the wrong IP address cuz I was using this at home so uh I have the the system IP wrong 192168 3185 so let's just do that and there we go so let me just log in here all right and now we're going to go into the uh the mega raade configuration so the reason I'm a little bit disappointed with the with the overall read speeds is you can see with well you would were able to see you can see with a twood drive array so this is using all the same raid configuration uh we were able to achieve 307 megabytes per second already now with ssds typically with a good quality RAID controller like we have and uh and a good quality SSD you should see almost completely linear scaling so while these drives are rated for uh 125 mb per second reads uh maximum you can see with two drives we were actually seeing that these drives perform a little bit better than spec and they're scaling extremely well because only two drives yield such strong read results now the this down here is the random uh performance so you can see even with uh eight drives uh random performance doesn't change very much so we've only got about 6,000 iops in 4k performance which is actually still very good compared to any hard drive I mean you got to sort of keep that in perspective but uh performance didn't really scale much from two drives all the way up to eight drives so you can see two drives we were seeing about 20 megabytes per second and then up to eight drives we see about 25 now with a deeper Q depth and a bigger array you do see more uh you do see better performance and what that means is that if you're multitasking a lot on a huge array like this you're going to see better performance and it will continue to scale versus if you're not multitasking and you're just uh reading and writing small 4K files now another thing that did scale really really well with adding more drives was the rights so you can see right iops are almost 3x when we add uh four times as many drives so that's still reasonably good scaling so I just want to show you the numbers as we go through here so remember this is uh eight drives this is the run I just did like two seconds ago and then this one here is with two drives so this is with four drives so you can see from 2 to four did not scale nearly as well so back to to two up to four did not scale nearly as well in reads as from 1 to two because from 1 to two we got almost linear scaling but you can see that especially rights scaled incredibly well so our sequential rights doubled actually a little bit more than doubled and then our 4K rights more than doubled so very very efficient there and so then from four drives I went to six drives so once again you see quite limited scaling in some areas but again excellent scaling on the sequential right so that's where we're seeing just just huge improvements and then finally this is an eight Drive run that I did before I I was using slightly better tweaked raid settings so that's probably actually the one I should be showing you more than more than any other one but uh but yeah that's how I was able to squeeze just a little bit more sequential readout of the whole thing and uh actually substantially better uh 4K random rights so anyway that was pretty much my video um I think that what we've discovered here is that using 8 ssds of uh very very low performance I mean the Onyx is a value SSD there's uh there's no two ways about it uh I think what we'd be better off with is using something like four to six higher performance ssds uh something like a Vertex 2 I mean vertex 2 right out of the box is going to outperform probably anywhere from 2 to to three of these Onyx ssds so what I discovered uh running this experiment is that you're probably better off with fewer ssds but higher performance ones so I'll just show you really quickly when you have a when you have a premium raid card like this how easy and how quick it is to set up a uh a raid array um all you really do is go into actually you know what no I can't show you this because I wanted to actually boot up to the uh to the SSD raid array so uh nope I can't wipe out my array but it's really fast you have to just believe me you click this button up here you select the drives you press raid zero and then there are actually some options that you can configure so if I go into my virtual drive here I believe I can go to Virtual Drive and I can s all the Virtual Drive properties so these are some of the things that that you can Tinker around with if you do set up an SSD raate array so I've set things up uh according to how LSI has recommended for the best fast Path Performance although some people do report better performance with no read ahead um and some people do get better performance with right back cach enabled as well as cash Dio it really varies depending on your SSD so you have to tweak and find out what works well with your controller and your SSD so thanks for checking out our little uh raid Zero Performance video don't forget to subscribe to lus Tech tips"}
