USB 3.0 Express RC8 Low performance?

Postby kjems » Thu Dec 20, 2012 9:34 am

Performance of the USB 3.0 Express RC8 on a Retina MacBook Pro (Ivy Bridge)

CrytalDiskMark 3.0.1 X64
500MB Sequential Random Data

Super Talent Express RC8 (50Gb)
Write: 33 MB/s
Read: 106 MB/s

Sxxxxxx Extreme 64GB USB 3.0 (64Gb)
Write: 189 MB/s
Read: 199 MB/s

How come the performance is so low? Is it a faulty unit?
I wonder if there is a firmware upgrade in the works that might improve performance?

Hello kjems,

I asked an engineer about your problem and he has asked if you would be able to provide a screenshot of the test results. He believes that you may have picked the wrong drive to run Crystal.

I have been using a long time to figure out what could be wrong and have lots of performance profilings. I hope that can put some light on what might be wrong. I have also tried several other USB 3.0 computers with only marginal better results.

kjems,

The engineer believes that you may have been plugging the drive into wrong USB ports. If you still have problems with the drive, the best course of action would be to contact the RMA department and explain your situation to them.
