Hello all, Anybody have any idea about why some USB flash disks show different writing speeds under Linux and Windows? For example the Sandisk's 32GB Extreme Contour drive can sustain ~17MB/second while copying big files under Windows but the maximum speed under Linux is ~4MB/second for the exact file. On the contrary, another disk I tested, a Corsair FlashVoyager GT 16GB can perform at its rated speeds (writing) on both platforms. Reading speed on both devices on both platforms is same and within their specs (25+ MB/second). My initial investigation pointed to queue depth difference of the Windows and Linux. I'll be very happy if someone can enlighten me about the situation. Cheers, Hakan P.S: I initially opened this issue as a performance bug on kernel bugzilla but the bug reported is rightfully rejected and I'm directed here. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
