I have a Sandisk 512 MB SUB flash drive. On my home computer, transferring to/from it is as slow as an ox, like over 5 minutes to transfer 100 MB. However, the same drive, when I use it at work transfers blazing fast, like 10 MB per second. What's the deal? All of my USB ports at home are 2.0. And it doesn't matter where I plug it in, either the usb ports that come attached to the mother board, or the extra belkin 4-usb-port pci card that I've installed. I don't get it. Anyone else ever have this problem?
