Hi, thanks for the replies. http://www.sonystyle.com/webapp/wcs/stores...7&langId=-1 don't confuse compatible and compliant... USB 1.1 speed maxes at 12Mbps both way(in and out) 12Mbps = 1500KB/s. I wouldn't be able to download from the device at 4MB/s if it was just USB 1.1. it's just that they used cheap memory modules for this device. --download from the device---- -- Done: 1 (101.55MB) Err: 0 (0) Skipped: 0 (0) Tot: 1 (101.55MB) -- -- Average Transfer Rate: 4.39MB/Sec -- Elapsed Time: 23 sec ------ ----Upload to the device---- -- Done: 1 (101.55MB) Err: 0 (0) Skipped: 0 (0) Tot: 1 (101.55MB) -- -- Average Transfer Rate: 822.95KB/Sec -- Elapsed Time: 2 min 6 sec ---- and the file wasn't cached on the disk or anything. the device isn't bad, the sound is crystal clear without background noise or anything. it's just that I wasn't expecting Sony to use cheaper than cheap memory modules for their player... even my cheap USB key is faster than that when i upload something to it.
