ssd iometer follow-up tests v09.31.12.txt

I needed to followup on my test results with the Iomega IX4-200d SSD iometer testing to see what could be going on.. see for the first set of numbers, but I will duplicate them here for comparision purposes.

The main goal was to keep the (4) Kingston SSDNow V-Series 128GB SSD Drives in a hardware RAID10 array throughout the testing process. I will drop the millisecond avg and max because it matters, but isn't the focal point..

Group_A: Iomega IX4-200d RAID10 SSD drives, 1Gb/s iSCSI to VMware ESX 4.0.0 bld 208167 with Windows Server 2008 x86 VM.

Group_B: Iomega IX4-200d RAID5 1TB mechanical disk, 1Gb/s iSCSI to VMware ESX 4.0.0 bld 208167 with Windows Server 2003 VM -

Group_C: RAID10 SSD Drives with LSI Logic PCIe MegaRAID SAS 8204ELP on Windows 7 Enterprise x64 direct IOMeter tests on the SYSTEM volume (C:)

Group_D: RAID10 SSD Drives with LSI Logic PCIi MegaRAID SAS8204ELP on Windows 7 Enterprise x84 with StarWind iSCSI Free Target with 1Gb/s Broadcom network connection
