If you are a person who is (physically) moving a lot of data around, you have only a few options: USB stick, notebook or USB HDD. A notebook is quite expensive, big and heavy and USB sticks might not provide enough capacity for you.

With the Thermaltake Muse you can put your old IDE harddisks back at use. You have the flexibility to upgrade to a bigger harddisk any time you run out of space.

While in theory it could reach 480 Mbps (= 60 MB/s), its transfer speed of 27 MB/s is on the high side, many flash-based USB sticks don't even reach 20 MB/s.

The external PSU is a little annoying, especially if you move the unit around a lot, but this is still better than some other external HDDs which run on USB power and don't work in many computers because they draw too much power.

Thermaltake is also offering the Muse in a 5.25" version for DVD/CD-Rom drives, and a 2.5" version for notebook harddisks.
