Hey guys, I have a huge movie collection and they r scattered across my many small HDDs. I'm running outta space and I'm plannin to buy my first large external HDD. I'm lookin for somethin RELIABLE. Should I opt for a 1Tb one? Are they crash-prone? If so wat brands should I avoid? Or should I opt for 500GB ones? Plz suggest me some good brands with casing [like the WD My Book]. Or should I go for portable ones? I'm not at all aware of the price tags so please include them. My price range is around 4k-5k. Plz point out the pros n cons. I need to make the buy real soon, so please gimme good advises at the earliest.
