24 Samsung SSD's in Raid...

Sad they had to use three different raid cards to jumble together the 2GB/s bandwidth, all to see how quickly they can open 50+ applications.

Samsung should have tasked them with some killer app demonstration to highlight the fact that the disk subsystem was no longer holding back those 8 cores on the board once the bandwidth got nice and high like that. (some beefy blu-ray transcoding or some such)

I would have thought that two or three Arc-1680's ganged together in raid-0 would deliver better than 2GB/s given that a single Arc-1680 can push 1.2GB/s on its own.

LOL...they used 2 x Corsair HX-1000w PSUs. I wonder if they were limited by the number of connectors vs how much power they actually needed? I need to read up on the power draw I guess.

In the slides buried in the last few seconds of the video they claimed they had to pull one of their vid cards because they weren't getting enough power to the raid cards thru the PCIe power lines.

I suspect that more than a dozen of our own AT forum members could have done a superior job putting together a rig with 24 SSD's than that half-assed rig done by their genius of an "IT guy".

I'm sure he did his best, and his marketing buddies wouldn't know the difference, but I am surprised Samsung didn't give a little more expertise in guiding them to put together a better rig setup.

Skulltrail? Really? I'm sure an i7 965 would have been a better platform for starters.

Well, if you want you could ask him(it guy) questions here...

I'm more confused about the Corsair TX-650 box when they show "The Build"
then later claim 2x 1000W PSU's?

nvm, the TX-650 was in front of the HX1000's

He explains the forced limitations fairly well in that thread, basically other than the samsung drives he was using stuff they already had and they ran out of money for the project which is why the raid cards got kinda wonky.

I copied it across the two RAID cards. We had two cards very high performance cards in there, but even so, both were maxed out by the drives. I ran out of budget to buy more cards.

Again my surprise is with Samsung, they hired these guys to showcase their technology in the best light, why wouldn't you make sure the guys had $10k of the right hardware to go along with the $25k of SSD's you just mailed them?

I take back my sarcasm above regarding the genius of an IT guy, he seems pretty knowledgeable, just resource limited for the project. I still consider it a half-assed rig though.

While watching I figured there would have been a wall at the number of HDDs supported via RAID cards. Quite frankly I am surprised that 1) a single RAID array can work across multiple RAID cards and 2)I am wondering at what point did the system get to a limited return on performance? It would seem that after 5-8 drives there is little to no return for any extra performance in a RAID-0 array, even with SSDs.

Freaking amazing.

With Areca card I know you can gang them together to support a raid array that spans multiple areca cards. Not sure if adaptec does this.

But they did not do this (gang raid cards), what they did was use expensive raid cards as pass-thru Sata ports to create a single software-based raid-0 spanning all the drives as windows saw them. Negating much of the value of the raid cards themselves.

Nobody on earth would actually spend money to setup a rig like this. But for a flashy youtube viral ad it worked like a charm, so you gotta give them props for meeting their objectives. Too bad it is as relevant to most of us as LN2 suicide runs on PhII at 6GHz.
