Sequential Performance vs. Transfer Size (ATTO)

I stopped putting these charts in our reviews (although I do include the data in Bench) because they are generally difficult to read. For this however I just want to illustrate two curves: a single Vertex 3 (240GB) and the RevoDrive 3 X2:

Obviously we're looking at compressible read/write performance, but the numbers are staggering. The RevoDrive 3 X2 is able to deliver just under 1.5GB/s in sequential read performance and up to 1.25GB/s in sequential write performance. What's most surprising to me is that these numbers are at a relatively low queue depth of 4. The incredible scaling beyond 16KB transfers seems to imply that OCZ is actually breaking up transfers above a certain size and striping them similar to a traditional RAID-0 array. Either way we're able to reach some pretty unheard of numbers here.

    Vista changed driver signing a lot. It added a kind of driver signing that do not require WHQL certification that meets the minimum requirements for 64-bit Vista and later fo load the driver. Reply

    I know desktop users are not the market segment for these drives, but I'd very much like to see these benched in a way that shows us just how much they can help productivity-- IE, I'd like to see how fast a Windows install with about 50-100 startup programs can boot with one of these, in comparison with a harddrive.

    I have never understood, nor used raid but I am really interested in this drive as I use a lot of high i/o intensive, large file manipulating software.

    My question is if the drive has a 240gb capacity, does raid mean that you can actually only store 60gb of real data? ei 240/4 raid disks.

    thanks four your patience if this is a "dumb question"/

    I would like to see how reliable these things are. I am still trying to get my Vertex 3's to stay up for more than a day without locking up or giving me a BSOD. There are thousends of us out there that bought these drives and are still hanging in limbo as OCZ continues with their "firmware of the week" program to try and make these drives stable. Until they can get the Vetex 3's stable, I wouldnt touch another OCZ product with a 10 foot pole. The fast speed is only usefull if the drive is dependable, and OCZ drives are NOT! Reply

    Where would FPS games fall - Heavy workload or Incompressible data transfer?

    What would be the expected through puts for games like Crysis 2, Mass Effect 2, Call of Duty (Entire series) Medal of Honor etc.

    I know this is an old forum but I'm having issues finding anything current on this drive, or at least after its release. I bought one and am playing games on it, granted all I play is WoW and EVE (I use it for a boot drive and use another SATA SSD as a storage drive). Said that Windows 7 64-bit can't boot from it, but for some reason I had no issue. Is that an indicator something is wrong or has it been fixed? (Probably a dumb question but just making sure.) Also, did they fix something about the TRIM support? I have fragmented drives because I thought it was supposed to be that way with TRIM and how it supposedly saves data to random spots to save cell lifetime (if I even understand it correctly), but if 7 64-bit doesn't support TRIM, does that mean I can defrag this thing for better performance?

    Also, sorry if that has already been answered, I've only been able to follow about half of this. Something about that it uses a SAS controller instead of a SATA controller to cut out more middle man kinda stuff with controller bridging (if I'm using correct terms) and that is what made it have so many issues.
