Hi,

Just bought 2 M4's and decided to run them raid 0 for my game installs etc, ( may eventually run it as a os setup )

anyway here are my current test scores, is this right? I thought the write speeds would be better, or is it a case that the M4's are good for read mainly?.

Im running

Asrock Z68 Extreme 4 Gen 3 mobo.
2 x 6950 > 6970 Crossfire.
2 x 64GB M4 Crucial SSD drives ( latest firmware already installed on these new drives ).
1 x Crucial 64GB M225 older SSD drive.
I5-2500k @ 4ghz at the moment.


when I setup the raid I did a 64kb stripe size, and a 4k allocation size within windows.

This is running on the intel Sata 3 ports on the board.

Seems about right. Write speed is 110MB/sec with firmwire 0009, so you should see around 220MB/sec. You don't need to RAID them though do you? You'll lose the TRIM function which keeps the drive nice and speedy over time...
 
Would also have thought that putting these in RAID will actually reduce the performance overall ? The TRIM function is something you definitely don't want to lose ...

After looking around at various forums I got the impression that the garbage collection on the M4 drives was bloody good and as such the lack of TRIM wouldn't be too much of an issue.

Plus there's talk of Intel including TRIM for RAID in their next chipset drivers.
 
Im thinking of doing the same, but with sata 2, just dont know if the trim raid feature will work on x58 intel sata 2
