It's big (both physically and in terms of storage), surprisingly nippy for an HDD (I'm actually getting the listed ≈260MB/s transfer rate), and works a treat. It's got a great warranty to boot!
The only downside is that it's a little bit loud when doing a lot of data transfer, but once it's in a case it's not particularly noticeable.
I would definitely buy another one.

I was looking for a bigger hard drive so I came across this one excellent build quality highly recommend using this hard drive for big storage and the delivery was quick and fast and the staff are very friendly and very helpful highly recommend using Wootware

Pulled the trigger on one of these to see if they would be a good fit in my server, the performance is excellent and obviously the capasity is amazing. I think this is one of the best hard drives you can buy now (price to capacity).
