Sata III Corsair SSD on a mxi x58 pro-e

Yes, just plug into first Sata II slot. Will lose some performance. Primarily on the Sequencial read/writes. But this is the LEAST important parameter for an OS +Program drive.
For installation of Windows (recommend a freash Install), first disconnect all HDD, reconnect after the Windows installation is complete
Don't forget to verify/set AHCI mode in BIOS.

When installation is complete, down load and install Intels RST driver (Newest is 10.8 I believe.

Down load AS SSD - don't need to run Bench marks unless you want to. But Look at upper left, it will:
Identify SSD and latest firmware
Should show driver = msahci, after update driver to Intel then should read iaSTor.
Will show that partion alignment is correct.

ENJOY
 
Correct, SATA3 Ports are backwards compatible BUT Intel SATA2 Ports are limited to 290MB/s~295MB/s. The Corsair SSD is 525 MB/s Read and 490 MB/s Write.

IMO for a few bucks more get a 128GB SSD, 60GB is way too small ; OCZ Petrol PTL1-25SAT3-128G 2.5" 128GB - http://www.newegg.com/Product/Product.aspx?Item=N82E16820227780

Most of the 'issues' in the feedback and with most SSD's is because folks fail to match-up BIOS = AHCI <=> Start = 0 and instead Windows is improperly set to Start = 3 = IDE and the wrong drivers are loaded.

Use 'Fix It' or correctly set the registry values; see -> http://support.microsoft.com/kb/922976
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV

Also, make certain the Firmware is up to date if available; see -> http://www.ocztechnology.com/ssd_tools/

This is common for all SSD's.
