Pros: Compact, sleek, very easy installation, horizontal/vertical placement, heat dissipating aluminum, power on/off switch, HDD status light, affordable.

Cons: Almost none I could find!

Overall Review: No eSATA, no cooling fan. However, for having eSATA, this could be expensive. Fan could be good cooling option, but fan may stop working after a while! Easiest HDD installation so far, does not need any tech experience at all. And, it works (1 TB Hitachi SATA 7200 RPM HDD inside).

Pros: Tiny, sturdy, high capacity, good-looking, standard price, decent speed, capless, lifetime warranty.

Cons: None that I can think of so far.

Overall Review: Some people complained it fits too tight in USB ports. I see that as an advantage specially when you hook this up with a keychain with a number of heavy keys, it does not come out! One word of caution: It is so tiny that you may get hard time to take it out of USB port, the best idea is to attach it to a lanyard or the given chain or keychain so that it helps. Those who think that it is so small that it may be lost must keep in mind that you are supposed to keep a back-up for a mobile drive. Those who are getting data corruption problem are either messing around with the drive or not patient enough to talk to Supertalent (lifetime warranty!). So far I did not see any data corruption.
