I just purchased a SanDisk Cruzer 1GB USB 2.0 flash drive. I tried copying a folder and it transferred extremely slow - about 4KB per second. It should a few orders of magnitude faster! Something is seriously wrong, causing the slow transfer speed on my iMac. The flash drive works fine on my PC. Has anyone else had this problem? If not, is there a certain brand of USB 2.0 flash drives known to work well on an iMac Core Duo?
