PCMark Vantage & SYSMark 2007 Performance

With four SF-1200 controllers in RAID, the IBIS performs well as a desktop drive but honestly most desktop workloads just can’t stress it. In our PCMark Vantage test for example, overall performance went up 10% while drive performance went up 30%. Respectable gains, but not what you’d expect from RAIDing four SF-1200s together.

SYSMark 2007 - Overall

The fact of the matter is that most desktop workloads never see a queue depth (number of IO requests that must be fulfilled) higher than 5, with the average being in the 1 - 3 range even for heavy multitaskers. It’s part of the reason we focus on low queue depths in our desktop iometer tests. The IBIS isn’t targeted at desktop users however so we need to provide something a bit more stressful.

    If I understood this correctly, OCZ is just using PCIe signaling over a SAS cable (with accompanying card to demux and pass on to the PCIe lanes)? That's ingenious. Reply

    This method also makes it easy to port it to a laptop interface through an express card socket. Reply

    Isn't that what PCIe RAID controllers do (minus the SAS cable)? Reply

    I'm pretty sure they communicate with regular SATA SSD drives through the SATA interface, whereas HSDL brings PCIe all the way to the SSD drive. This would be why IBIS supports much higher IOPS than previous PCIe SSD solutions like the Z-Drive (which were limited by SATA RAID). Someone please correct me if I'm wrong about this. Reply

    675 MB/s in sequential write? I just feel sad all of a sudden. SSDs are so forbidden for me right now, but this is a true monster. Maybe they'll make a more "down-to-Earth" version next time. Good stuff, anyway. Reply

    If only I could burn DVDs that fast. Reply

    You still burn DVD's? Hell, I stopped doing that a few months ago when I realized that 99% of the stuff I burned was really a 'watch-once and never again' thing and went out to get one of those 2.5" 1TB external hard drives.

    Haven't burned another DVD since.

    too much proprietary peripherals, if i am going to use a PCIe card, I might as well just stick with a revodrive. pcie slots, proprietary slots connectors, proprietary cable, proprietary disk drive interface, blah. ill just stick with their own revodrive for now and wait for sata or sas controllers to pick up speed.

    SAS cabels aren't that expensive these days, and the most companies who would by one of these use them today anyway.

    And good luck waiting the next 3-5 years or so for SATA 12GB ;)
