Slow cards or slow card readers

An interesting reminder that the hardware on which you test the media may cause a noticeable difference:

Media: SanDisk 8GB Extreme SDHC Class 10 High Performance Memory Card (SDSDX3-008G-P31).
Lenovo T61 built-in SD card readerKingston Media Reader FCR-HS219/1


Notice +25% improvement to maximum write speed, and also notice different shape of the graph: faster card reader would reach maximum speed much faster as block size increases.
