The values for Class 10 are of course met (10 MB / sec sustained write performance). In my not slow degrees "Digisol 4.1" -Cardreader (USB 2.0) are 64-bit reaches about 12 MB / s write performance and about 22 MB / s read performance on Win 7 (according to speed indication when Total Commander). Under Win XP SP3, the read performance is about 19 MB / s, the write performance is like under Win. 7 To measure a 1.7GB large file is copied. The memory card was formatted in the measurements with FAT32 (ex works). I bought 2 of these memory cards, they behave in terms of performance both equally. I'd like to know under what conditions the 30MB / s were reached at Toshiba.
