I am looking to buy an external HDD in the 200-500GB range to store all my music and video files, to both help keep my internal HDDs uncluttered, and also to have all that information in one place. Just wondering what to look for, as well as possibly some recommendations. I also have a few questions: 1. I know when shopping for the main HDD for a computer, criteria to look for include spindle speed, seek time, cache size, data transfer rate, etc. However, if this drive will only be used to stream music/video files off of it, not for loading OS and other programs, do any of these features become less crucial? Also, almost all of the external HDDs I've seen so far connect via USB 2.0. Does this put a cap on the transfer speed, or is it fast enough that the criteria mentioned above still apply? 2. Relating to question 1, browsing around I've seen some HDD cases that effectively turn a regular HDD into a external one. Is there any downside to doing this? Is buying a regular HDD and sticking it in a case a better value than buying one designed to be external? 3. Encryption. I'd also like to have one folder on the disk that contains sensitive personal information such as passwords, online banking stuff, etc. I'd also like to protect it with something a little beefier than a simple password. I know very little about encryption technology, but is there some way that I could put a PGP-type encryption on the whole disk, and that would have to be first bypassed before anything could be accessed? Thanks for your time.
