I need external HDD space for the following uses: 1) Storing movies and watching them from the same drive. 2) Downloading torrents 3) Time machine back-ups of my 80 gig Macbook HDD, which I may upgrade in the future. It seems to me that a single 750 GB external drive with FW400 should be enough for my needs. I understand that downloading torrents and watching movies on the drive will put constant wear and tear on the disk, which makes it less than ideal for back-up storage. However, as I do not intend on keeping original important files on the external drive, only back-ups, I figure I should be safe if either my MB or external disk craps out; I'd only be out my movie files - a pain to re-rip but not disastrous. I'm looking at the following items on Newegg : -- Western Digital Caviar SE16 WD7500AAKS 750GB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM - $130 -- http://www.newegg.com/Product/Product.aspx?Item=N82E16822136131 -- ICY DOCK MB559 MB559UEA-1S 3.5" USB2.0 & 1394 External Enclosure - Retail - $45 after $15 discount and $15 rebate -- http://www.newegg.com/Product/Product.aspx?Item=N82E16817198004 Sounds like a good set-up? Any second thoughts before I pull the trigger?
