Examining Performance: Windows 8 Storage Spaces

Update 8/12/2012

I picked up another RE4 500GB so now the test is using two Western Digital RE4 WD5003ABYX 500GB 7200 RPM 64MB Cache SATA 3.0Gb/s drives.

The first WD RE4 500GB on SATA2

The second WD RE4 500GB on SATA2

Now inside of a RAID1 created on the SATA2 ports for the ASRock Z77 Extreme4 motherboard. Using the two WD RE4 500GB drives from above.

And now inside a mirroring Storage Space on Windows 8 Release Preview.
