MODELCHECKER Posted August 17, 2009 Share Posted August 17, 2009 hi all, we're about to configure a 32GB RAM Mac Pro for some memory-consuming computations (hence the nick). Our plan is to use four Corsair 256GB SSDs with Apple's RAID controller in RAID Level 0 mode. Has anybody any experiences? Link to comment Share on other sites More sharing options...
GaPony Posted August 17, 2009 Share Posted August 17, 2009 I did 3 P128's in RAID 0 and found the scaling to be very good for sequential reads and writes. Random reads and writes didn't provide as much of a performance boost. All in all it performed very well, but I was just doing the testing while I had the three drives together. I purchased them for other purposes. You will absolutely need a good RAID controller card. I used the Adaptec 5445 with 512mb cache. The Intel ICH10R onboard controller couldn't handle it.

Corsair Employees RAM GUY Posted August 17, 2009 Corsair Employees Share Posted August 17, 2009 From what we have seen in testing any of the raid cards that were 300+ USD all performed well and would need to be PCI Express 4 x MIn 8X suggested.

MODELCHECKER Posted August 18, 2009 Author Share Posted August 18, 2009 Thanks for your replies. We'll have to check what kind of controller Apple mounts in their Mac Pro series. They're not overly informative on that issue but the SSDs they offer with it are out of this world (concerning the price/performance ratio). We'll report as soon as we know more...

Corsair Employees RAM GUY Posted August 18, 2009 Corsair Employees Share Posted August 18, 2009 Both Hi-Point and Adaptec offer Mac compatible Raid controllers and would offer above average performance. Link to comment Share on other sites More sharing options...
