Top Customer Reviews
I tested the card reader on Windows 7 and Linux. Note that it is documented to work with Windows and Mac, but I have successfully tested it under Linux as well.
I tested with microSDHC Class 6 Flash Memory Card and Class 10 SD card.
Each operating system I tested saw USB memory sticks and cards plugged into all slot in the card read without problems.
To evaluate similar devices I test each by copying the same large set of mp3 files totalling 638916 Kbytes. I measured CPU time and clock time. My goal is to test that each port works, and to compare the performance relative to other card readers I have tested. Since I use the same set of files I can compare different devices in "apples to apples" comparison.
I ran each test three times to make sure the results were consistent.
TEST #1 SD card
1.551s (cpu) 1:48.54 (clock time)
TEST #2 micro SD card
1.373s (cpu) 2:24.55 (clock time)
I received this card reader for testing and review from the manufacturer. The card reader performed well in my tests. It was not the fastest card reader in my write test, a larger card reader which had external power performed slightly better (1:09.36 clock time for micro sd and 1:27.81 clock time for sd), but the small size makes this card very convenient to use. I find it especially handy to use with my laptop which does not have a built-in card reader.
Ali Julia review
This card reader has 2 main ports, one for Micro SD cards and the other larger card slot supports: SD-XC, SD, MMC, RS-MMC, SD-HC. One feature I really liked about this unit was, while using a standard SD card with this reader, I was also able to use a Micro SD card at the same time.
This product was easy to setup and use. It is self-powered by the USB port it's connected to, so there is no messing with additional power cables. The unit is compact, however it's a little wide and could potentially block other close by USB ports on a computer or hub. I tested this unit on Windows Vista, 7, and 8 Machines and it was recognized and performed as expected on each. Though this is a USB 3.0 card reader, it is backwards compatible with USB 2.0 ports making for great flexibility in use.
Overall, the card reader looks good, and feels solid. It works as it should, providing lots of options for all the memory cards we often carry around. It was most useful for a netbook I have that has no card reader. As an avid amateur photographer, this was a much needed enhancement.
Disclosure: I received a sample product from the manufacturer for the purposes of providing this review. A review in exchange for the review sample was not promised. The views and opinions expressed in this review are my own, and in no way represent the views or opinions of the manufacturer or vendor.
The ONLY reason I gave it four stars is because I would like to be able to attach a lanyard or something to it. Not necessarily to attach to a key chain or anything, it's just a personal preference in how I store my gadgets like this.
There are a couple of key features that I like about this card reader. The first and most obvious is the USB 3.0 speeds. This reader had no problem maxing out my 45MB/s and 90MB/s Sandisk Extreme and Extreme Pro cards, though keep in mind I was transferring to a Solid State Drive with max write speeds of 200+MB/s - you WILL need complimentary hardware to experience the full potential of this reader.
The second thing I love is that it has a dedicated MicroSD slot on the reverse side. I often have to search my office for my MicroSD to SD adapter card, and this reader totally eliminates that. MicroSD cards are naturally a little bit slower in terms of transfer rate, but again, the reader maxed out my MicroSD card.
The reader comes with caps at both ends. Personally I would have preferred one of those rubber/silicone caps that stays attached on the card end - like what you find on most DSLR cameras, but keeping track of a cap is much less of a hassle than trying to clean out dirt from a card reader, so no points off there.
Overall, this card reader offers solid speeds and a slim profile - the finish (black brushed aluminum) is a nice touch. At ten bucks, I can hardly find anything wrong with it and highly recommend it at this point! I will update in the future if anything goes wrong, either with transfers or loss of functionality.
