Crucial M4 128 GB x2 in RAID 0 - Performance benchmark?
I've got a pair of these on my main rig (Asus P8Z68 Deluxe, i7 2600K, 16GB Ram). I've chosen to use the Marvell Raid controller that supports 6 Gbps, but I'm not sure that I'm getting the performance metrics I should be seeings. These speeds appear more in line with using only a single SSD and not RAID 0. At the moment. I'm debating if I should rip the raid apart and then just stick the extra SSD into my laptop to boost its performance.
DO NOT use marvell controller because you are limited to 5gb/s max bandwidth!
so you're getting 2,5gb/s per SSD! which is less than sata II 3gb/s!
your motherboard have 2 x SATA 6Gb/s ports(gray color) which is a part of intel z68 chipset!
also 64K~128K is the best stripe size for your ssd's!;)
do not forget to check for bios and intel chipset driver update!
