So I'm in the market for an External HDD and from what I've been reading the new Seagate HDD's are being reviewed and rated very well from people. But when I was searching for External HDD's before I remember people saying that the bigger drives are less reliable than say a 320, or a 500 GB drive. I can get this 1.5 TB drive for $190 on Newegg, and the 500 GB is about 140. So I can easily say the extra $40 is worth it for another TB of storage - but is it still too big? Can people safely say really big HDD's are more reliable now than before?
