Pros: 1TB, of course

Cons: - Drive is large, may not fit in your laptop - Seems to be high failure rate, looking at reviews - Mine was DOA

Overall Review: Mine was DOA upon receipt. No problem, these things happen. WD RMA process was pretty painless, they shipped new drive before I had to send old. However, I had to pay return shipping. I could understand if the drive was 2.5 years old, but I just received it. Drive doesn't fit in HP DV9700, but that's my fault for not confirming first.

Pros: Cheap, got them for only $10/pair. Sound and comfort are as expected for the price.

Cons: Constant hiss when plugged into any source. Suond is a little 'muddy'. Can be cleaned up with a little EQ, but can be annoying if using on a PC where you switch back/forth between these and speakers.
