I have about 4-5 external hard drives and they work great, for the most part, but the major drawback is the huge amount of noise that some models make, especially the LaCie drive I have. That fan on my 200gb D2 drive is actually louder sometimes than my dehumidifier.
So I’m really geeked about this fanless external LaCie drive. And at only $329 for the 500gb version, you can have a terabyte of external storage for under $700.
