    Exclamation Unanswered: SQLIO : Performance on SSDs!!! Interesting results on Server7 aka Server2008R2

    I issued a command like this:
    sqlio –kW –s60 –frandom –o32 –b8 –LS –Fparam.txt

    The 3 OSes, all on the same piece of hardware:
    Server2008: Host for VMware Server 8GB RAM in total
    Server2003R2: VM on VMware server 3GB RAM
    Server7/Server2008R2: VM on VMware server 3GB RAM

    Storage: 6 Intel X25-E 32GB SSD on RAID 0

    Server: Intel Modular Server

    To my surprise, Windows Server 7 aka Server2008R2 is giving better IOPS than Server2008!!! How could VM perform better than the host? Amazing...

    Results are shown in the attachments.

    Going to try out X25-M as the new 8820 firmware seems to maintain the random write speed at 70MB/s... I can't imagine when all the 14 HDD bays are loaded with these monsters......

    anyway, what's the right command options to push the drive to its limit?
