The Akasa ICR-17 is one of the few card reader that actually work with USB 3.0. Many other card readers have only one loop-through USB 3.0 port, while the cards themselves are read with USB 2.0 speed.
The reading speed with a Kingston 2GB SD card (Class 4 probably, not specified printed) was the first test at about 25MB / s, which is many times more than the card specification (Class 4: 4MB / s) is!

Negatives:
Unfortunately I could not reproduce this value and also test any more cards, because the card reader no longer worked at the next PC startup (no longer appears in the Device Manager, even after re-installation). In an exchange with a working device I have omitted because of other negative points (-> return, refund).
To connect the card reader a lot of cables are necessary, the situation on the motherboard should therefore be checked before buying. You need:
- 1x Molex (Stomversorgung)
- 1x USB 3.0 19-pin internal
- 1x USB 2.0 9-pin internal
(To be normally out the back of the case and there plugged into the external port) 1x USB 3.0 Type A -
- 1x eSATA
It is also disturbing that all USB ports, and an SD card slot are built upside down (!)
The card reader all the equipment were all displayed under Windows 7 as single drives named "Removable Disk". This is confusing and there is no driver for the change (but you can, provided you have appropriate knowledge, Windows-own options, or third-party programs, such as USBDLM use it).

Conclusion:
The high reading speed has surprised me - as specified by a USB 3.0 card reader would do only for (the more expensive) SDHC / SDXC card sense, since the reading speed "normal" SD card anyway slower than USB 2.0. But nevertheless apparently went much faster. The disadvantages mentioned, however, outweigh the particular defect is equal to the second use. I would have awarded 3 stars, but that the Erstrezensent has also first get a defective unit, suggests that the series is not very mature, which again is a point deduction.
Other (actual) USB 3.0 card reader is available from BitFenix and deleyCon. In reply, I had already, he was broken from the start and had also built wrong slots. So I'll now try finally with the BitFenix ...
