Crystal disk mark, ATTO or HD Tune are 3 good ones. I prefer ATTO.

Checked with ATTO :

Any ecipher guessing Im getting 350mb/s how to this equate to the suggested transfer rate 5-6gb?
Is it below par and would I notice much difference should I install on a SATAII connection with the drive?
Thanks

Your system specs say you have a Vertex 2, is that correct?

Incorrect installed is a Vertex 3 (the vertex 2 has been removed and jiffy bagged for RMA).
Incidentally Ocz have confirmed will be replaced with a Vertex 3. So eventually I will 2 x Vertex3 120gb SSDs installed.

The vertex 3 claims to get 550MB/s read and 500 MB/s write. So, you look to be getting 170Mb/s or so below that.However, what they never tell you is what the 4kb read speed is. That is about 95% of what an OS does. For an OS drive, 4kb reads and response time are the only 2 things that really matter. I have nothing to compare that to. You can tell by looking at the sizes, you only get to the higher speeds with very large reads, which an OS almost never does, and most people never get exactly what is claimed. You can try it on another port if you like, but I ran one slower than that for a long time and loved it.

Mark any non-bootable partitions which are currently Active beside System Reserved inactive: Partition - Mark as Inactive - Windows 7 Forums

In addition on Disk2 you have a RAW active partition which I would wipe to repartition the HD: Diskpart Clean Command.

Either the Active flag or old boot code on another hD can slow or interfere with an OS booting.

How is performance using the internal SATA port. You may need to run a Startup Repair but Win7 should have the SATA driver.
