I just got to download photos from a 32 GB Patriot (class 10) card,
and this reader is working extremely well with it.
The sustained rate of 32-33 MB/second for reading from this reader
connected to a USB-3 Express-card (and the HDD connected to the same
USB-3) is very good.
I suspect that some limitation might be also on the bus side, since
both devices are on the same bus.
For comparison, using any of the built-in and two other USB-2 card
readers, the best sustained rates I could get with this card (and other
Class-10 SDHC 32GB cards) was 13-15 MB/s, if I was lucky, and frequently
not exceeding 10 MB/s.

Hi Rob,
Thanks for your response.
After sending the message, I actually found this exactly model on B&H
and even put it in the shopping cart. So, you confirmation is helpful.
I don't seem to see any that supports UHS-3, but I think I am not going
to buy that expensive card at the moment either... It would've been nice
to get a reader that would last longer, as I am sure one of the next
generations of the "serious" cameras (DSLRs and possibly mirrorless)
will start supporting UHS-3, - actually, as soon as they would add
the gimmick of "4K" video.
I found that SanDisk Extreme PRO UHS-II SD supports UHS-II, but
I am not sure if it is what UHS-3 is... I am confused by UHS-II...
In any case,- it costs from $45 and up, and reported (on B&H site)
to be fragile... So, I am not going for it.
Cheers,
Igor

Hi Igor,
I'm running the Trancend TS-RDF8K
http://www.transcend-info.com/Products/No-331 with SanDisk 64GB
Extreme Pro SDXC UHS-I Memory Cards (95MB/s), it works well but no
indication of support beyond UHS-1
Cheers,

Does anybody know if all USB 3.0 SD-card readers are capable of
UHS(-1/-3)?
I would assume that it would be very logical, but I do not see
that mentioned explicitly in the specs.
Any thoughts on this?
Also, - any recommendations for fast and inexpensive USB 3.0 SD card
readers?
Thank you,
Igor
