~150 MB/s sustained transfer rate between sata III hdds in same system?

post #1 of 3
Thread Starter 
Is that about right? Seems slow to me. Burst is higher of course, I'm talking sustained. These are 7200rpm platter drives. And I do know these drives don't use up the sata III bandwidth. But I thought they'd be faster than this.

USB 3 external transfers ~70-80 MB/s, USB 2 external drive transfer is ~35-40 mb/s.

Yup that seems about right for a modern mechanical drive. I get about similar numbers when I capture an image of my drives (all SATA III mechanical) which is just one big sustained transfer.
