Wow, lots of hard drive fanboys in here. Well, the data suggests Seagate is less reliable. I've owned a lot of different drives since my first computer when I was a kid in 1996, and I used to build PCs for myself, friends, and family. Seagate and Maxtor were the only drives I've ever had fail. Guess who bought Maxtor in 2006? Seagate. My most recent drive failure was a LaCie, which was a couple years ago. At the time I wasn't aware of what drives were inside these machines and picked it up for a good price. Luckily I had a backup on a WD drive. Funny that people point to the 4TB Seagate drives as not failing as much. Well guess what? The 4TB drives are the newest and haven't had time to fail. The failure rate may or may not go up, but given the history I would bet they'll get worse. When it comes to data security, why risk it? Just buy the most reliable brands: WD and Hitachi. I like higher end Hitachi drives for everyday use because they're fast, and backup to cheaper WD drives. This isn't like Mac vs. PC where the experience of one isn't easily comparable to the other. These are hard drives! They're a commodity, people! Just buy the best component. It's quite a logical decisionespecially when prices are similar.
