P6X58D Premium USB 3.0 speeds

What kind of write speeds on a 1 gig movie file
could I expect? I'm seeing about 20 MB/S to a
Lexar LJDS73 16 gig stick. The strange thing is, it's
the same speed on my 2.0 ports...
I have updated my bios and the usb drivers to the latest.

Thanks,
Dave

 

To calibrate bus performance, you should be using read tests.
If you use write tests, the flash chip performance could be
the bottleneck. Reads offer the best opportunity for heroic
results.

Run HDTune benchmark against your S73 and see what you get.
I have an S73, and I get 35MB/sec over USB2. I have no USB3
to test with! The S73 can only go a little faster than that,
over USB3. Maybe 45MB/sec reading. Test it and see.

If you do better than I did (35MB/sec), then I'd say USB3
protocols are working for you.

Example:

Read Speed up to 45MB/s
Write Speed up to 20MB/s

There you go. You'll only be dazzled, during the HDTune
read benchmark. If you see a flat line at 45MB/sec, it's all
working as it should. On writes, you'll see little difference
between USB2 ports and USB3 ports. Because the flash chips
are the limit.

Thanks Paul.

There doesn't seem to be any setting on HDTune to tell if it
is benchmarking reads or writes.
I am getting 33MB/s on usb 2 and 43MB/s on my usb 3 port. I was
thinking my S73 was capable of more than that.

That sounds reasonable.

I got 35MB/sec on USB2.

The 43MB/sec number, is slightly less than the 45MB/sec
promised by the advertising copy.

The thing is, for the S73, the 20MB/sec writes won't strain
either USB2 or USB3. So we can't really do write tests and hope
to prove anything.

HDTune Free does reads only. HDTune Paid Version does both
read and write. The Free version is safe, as all it can do
is read testing.

There are some USB3 sticks out there, which go faster than
the S73. A little pricey though. Not quite as thick
as the first generation Patriot quad-channel ones.

Capacity 64GB
Read Speed Up to 200MB/s
Write Speed Up to 120MB/s

I got my S73 on sale and have no complaints about it.

Ditto for me on the S73...as a matter of fact I bought 3 of them! That gave
me more storage space than the 32 gig one I was looking at, for the
same money.
No complaints, now that I know that is the speed it's capable of. I was
thinking my MB had the problem.

Thanks
