I have six of these, and I've ordered two more. I use them with a Popcorn Hour A-110 media player.
They're not the quickest USB drives in the whole World, but they're reliable, reasonably priced, they look nice, they're quiet, they run cool, and they're stackable - if, like me, you have a spiralling media habit, when you need to add another drive you can pile it on top of the others.
A testament to how good these things are - they're really, really hard to find. PC World, Currys and places like that get stock every two or three months, then they sell out in a couple of weeks. Even Amazon, with their enormous bargaining power, have to wait two months for stock... think about it!
