CAUTION PRODUCT CHANGE !!!! For several time I order this article that door (was) the reference SanDisk SDSDQR-8192-E11M, ie the pack MobileMate MICROREADER for μSD, μSDHC and M2 with μSDHC 8 Gigas in Class 4. Well, that's the past, you now have a μSD / SD adapter without the USB drive (contrary to what the 2nd photo), so it is cooked for you if your PC does not support reading / writing SDHC (more than 90% of the French Pc park). The card is now μSD of Class 2, ie that there has slower SDHC (still much faster than conventional SD). But actually test done with Atto Disk Benchmark and MobileMate MICROREADER (not supplied), the measured actual flow rate is the same as the class 4 or 16 MB / S in writing and 19 MB / S in reading. Always less than 10 minutes to fully charge the card from a PC
COMMENTARY OLD The Micro SD reader that accompanies μSDHC 8 gigas Class 4 SDHC is 100% compatible, because even with the same manufacturer Micromate it was impossible to copy files larger than 2 gigabytes, this caused a device error whatsoever XP or Vista, throughput displayed by Vista write is 11.9 MB / s !!! Throughout the writing of a 7 Gigas file and error in less than 10 minutes !! (though class 4 = 4 MB / s !!) Admittedly, this is a horror to exit the μSDHC this big reader as a thumbnail (without operation indicator), you must pull a corner, the problem is that this player is also a Memory Stick M2 reader So with 2 rows of contacts. The first step for the M2 and the 2nd notch (down completely in the card reader) is the μ SDHC
