I have 2 Crucial MX100's 512GB SSD's raid 0 (windows software raid) that write to drives at 250MB/s no matter what other drive I'm writing to.

I have a Raid 0 (two 6TB Seagate spinners) (four 3TB Seagate Spinners) and a Samsung 840 Pro 258MB SSD.

All write media files at 285MB/s. The SSD's are on the motherboard 6Gbps controller.

Windows 7 x64
Latest AMD AHCI driver
AMD 8core cpu @ 4300Mhz


Seems that the max write speeds for the drives should be achieved. What makes me suspicious is that all writes from the Crucial array are exactly 250MB/s

Any suggestions?

The Crucial M500/ M550/ MX100 have never been known as fast drives.
