Well, first of all (since this is ur 1st post)..
a.) Welcome to the Forums..
b.) THis (Reviews) is the wrong section to be posting ur querries, it shud be in QnA section, so reported ur post to be moved to the QnA section

As per ur requirements, here are the possible options:
1.) WD (Western Digital, has a glossy finish body, so really prone to Fingerprint marks, hence u'll hv to buy a separate pouch kinda thing to protect it from marks..)
2.) Transcend (it has a rubbery type of body surface cover, so NOT AT ALL prone to finger print marks unlike the WD and also has passed the so called "U.S Military Drop Test" wich is simply, if u careless and happen to make this protable baby fall from a height of 2-3 ft, it will STILL work flawlessely, I hv tried it infact tried 10-12 times in a span of 3 days to test it)
3.) Seagate (It has a really gr8 portable HDD in Brushed metal kinda type and in white color along with many LEDs arranged in semi circular fashion)
Well all of these Portable HDDs are really good as all are really compact in size and fits really gr8 in the palm of ur hand..

Cheers n e-peace...
