Fastest HDD with sequential read/write speed of 280 MB/s. Just plug it in, inspect the disk, and you're ready for everyday use. It's easy and convenient, and because it's for businesses, it has a MTBF of 2.5 million hours, making it a great HDD. However, it also makes a tremendous noise and vibration when accessing.

Seller is using bubble wrap instead of foam to ship these. 3 in a box. the box was completely dented in and one of the drives has a dent in it. Somehow the drives weren't DOA but I'm not sure about the longevity of them.
