I'm about to order a hard drive that I will mainly use for backup over my wireless network (AEBS) and sometimes directly to my computer. I'm mainly concerned with reliability: 1. WD my book pro 500gb 2. Lacie Quad D 500gb 3. Segate freeagent pro 500gb They're all about the same price - how'd you rate the companies and the reliability of their products? Thanks...I hate reading customer reviews, just confuses it all.
