Top performance, only a small weakness

CSL All in One USB2.0 Card Reader (8,89cm (3.5 "), 2x USB3.0, SD / SDHC / mini SDHC / Micro SDHC / XD / CF / MD) (Personal Computers)

Customer Review

On my PC, I have read only two rear USB 3.0 ports and SD card to an external I SD Card Reader. It should be something permanently installed here, with all ports are available in the front.
Since the CSL - 3.5 "All in One USB 3.0 Card Reader is convenient and everything required on board, he immediately came on the short list.

The difference in price for similar equipment is partly at 100%, which leaves a queasy feeling when buying.
Return does work and I do not want.
But the feeling was not confirmed.

Attention!
The title and description are very deceptive. The card reader itself has only USB 2.0!
With USB 3.0 really is meant only the two USB ports.
More on that later.

Shipping and Packaging
I've bought from Amazon, so as usual quickly.
The packaging of the card reader with USB 3.0 ports is very poor.
In the shipping parcels, the size of a thick book, the unit is already directly wrapped in a sheet.
There are as nothing really to unpack.

Instructions
None, neither an information sheet, a brief description, or how to install it lies.
Also available for download, I have found nothing after 15 minutes. Internet research.
One should know how rum the USB 2.0 connector has to be plugged on the motherboard so already.
The USB 2.0 connection is the smaller of the two connectors. On plug itself you can see the individual colors.
The red cable must be connected to the USB Power. Whether that is now left or right on the motherboard can be looked up in the manual of the mainboard.
When USB 3.0 connector, you can not go wrong, which is protected against reverse polarity.

The very lack of documentation is already the only weakness and is a star deduction.

Installation
The unit is pushed into the 3.5 "bay to the chassis, in which it fits perfectly. This is the bay where formerly were the floppies.
Who does not have the, you should get a 5.24 "mounting frame. Or tighten the device only on one side.
Screws, incidentally, were not there. The one should have it myself. Although this is unusual, but absolutely forgivable in the price.
After the connector 1x USB 2.0 and 1x USB 3.0 are plugged into the motherboard.
Cover to the computer and ready again.
Under Win 7 no further installations were necessary and the device is recognized immediately.

Cable lengths
The length of both cables is sufficiently long.
In a Midi-GheƤuse it will thus be sure no problem.
Personally, I have no big tower, but also it should be sufficiently long cables.

Operational
Once the computer is switched on, the red Power LED. Is the reader or the USB busy, the green LED lights.
The USB 3.0 connector from the stick and also from other cables go very well.
The SD Card can be plugged easily. It hooked and not work as smooth as silk.
When SD card I thought indeed only that the completely pure must in the slot, but quickly realized this is only the first quarter pure.
When transmitting data, there was no problem, suggesting poor contacts.

Speed
Measured I have nothing, but looked at the practical values.
When you create a backup of the internal hard disk to a USB 3.0 hard drive that were connected through the plug I had 35 MB / s on average. This is a review in exchange / read and absolutely normal.
When copying a 1GB file from the external USB hard drive to the internal SSD were rising more than 150 MB / s, trend. But the copying process was completed.
Copying from an SD card (read only) was on average 17 MB / s with a mix of photographs and pictures (177 files, 1.67 GB total).

Summary
In total this is a very great device, well finished, with matching slots.
The price / performance ratio is very consistent.
Only the not available documentation is bad and leads to the one star deduction.
