Hello,

I have 3 32gb ssd sata II drives in raid 0 .. will i see an improvement in performance if i move them to a sata III board with the higher bandwidth? or do the drives cap it.

More about : raid ssd

Probably not

Each drive has the full SATA II bandwidth available to it and they can only saturate this in very rare, momentary, circumstances.

^+1 Agree.

If they are SATA II 3.0Gbps, that's all they can do. Moving to SATA III port won't help, it's the drives. But SSD come far closer to the bandwidth than HDD.

But you have a 3 drive RAID 0. It's gotta be screaming fast! DO you have any benchmarks?

It seems to me the writes don't scale nicely. What do you find foscooter? I wonder what the next gen will bring.

Like the Vertex II at nearly 300MB/s read AND write. The 120gb was on sale yesterday for 279 CAN (after 30 mail in rebate). I was twitching let me tell you.

I posted my benmarks here: Intel SSds in Raid 0 - Long term use

My SSD RAID 0 array peaked at over 437MBps reads, average 232MBps reads. Writes were in the 50MBps range.

I can only image have much faster my system would be if I got a different drive, like Intel X25-M 80GB Gen3 upcoming, with or without RAID 0. Although OCZ Vertex II maximum speed crushes Intels: Intel=250r, 70w | OCZ=285r, 275w.

What benchmark do you recommend to test SSD on w7 x64? the ones ive tested either dont test ssd or dont work on w7.

WEI is

7.4 < cpu
7.4 < ram
6.8 < graphics
6.8 < ^
7.6 < 3x32gb ssd raid 0

Try HDTUne.

But it's only free for 15 days.

It is the one I used, and yes on Win7.
