DiskMark Sequential Read/Write
I just ran DiskMark on my drives and was surprised that my RAID data array (1) was several orders of magentude faster than SSD or USB3 on read.
Surely this is a bug?!

Gotta be a bug - just got 142mb read and 86 write out of my 120GB Vertex 2 (which is resonable) but GB/s just isnt possible.
Did you do a re run at all?

Totally a bug, probably an issue with the junk Intel drivers.

I thought the same.
I assume USB3 will be majorly faster than a stock Intel RAID chip though?

Still depends on the drives, if your talking SATA2 thats 6GB/s which kills even USB3 for throughput at 4.8GHz. With a low end Intel RAID controller in the way though results will vary heavily. To get to these speed levels you really need to be looking SSD anyway so the whole point becomes moot.
