Hi everyone,

I've got a bit of a newb question about SSD's.

I have an OCZ-Vertex III SSD as the primary drive on my PC.

My motherboard is a Gigabyte GA-X58A-UD3R (rev 2.0).

The SSD is connected to the Sata revision 3 ports.

What read/write speed should I expect on the SSD?

I've done a couple of tests and I'm getting read speeds of around 200MB/s.

My understanding was that SATA revision 3 and SSD's were capable of up to 600MB/s.

Should I be concerned by this or is this a reasonable result?

If something is markedly wrong, are there settings in the BIOS that I should adjust or is it something else?

600mb/s is not reasonable, more like 400-500.
The problem, I think is the sata 3 implementation on your motherboard.
I think it uses a Marvell chip which is not as good a performer as the intel implementation.

I would not worry too much since the os does mainly small random reads and writes. It does much less sequential work.

The only setting in the bios should be to set the sata mode to AHCI to enable trim.

It really depends on what kind of test you're doing. 200MB/s would be amazing for any kind of random read on a single SSD. Sequential reads would be just like Geofelt said, in the 400-500MB/s range. What test(s) are you running?

Just a read test using HD Tune Pro 5.50
