PC Apex have a new review up on an extremely versatile 3.5" bay which offers a way to read every flash card

Moving on, the Infinity-Drive?- which sounds like it should be something out of Galaxy Quest is actually an aluminium 2.5? USB ATA notebook drive enclosure. It has a brushed, anodized finish with plastic end caps and very little else worth mentioning - apart from the USB port and a little black hole in the back. It is easily removed by simply pulling it from the bay.  When removed, the empty bay is covered by a spring loaded plastic door designed to look just like the front of the enclosure.
