OCZ's Fastest SSD, The IBIS and HSDL Interface Reviewedby Anand Lal Shimpi on September 29, 2010 12:01 AM EST
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.
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.
