-Can be a bit noisy but most 7200rpm disks are. Depending on computer cases it might not be noticable.

I installed 6 of these 4TB WD Red Pro HDDs into a NAS (RAID 5) and they work great. They come without screws for mounting so you will need to have some 6-32 x 1/4 screws with a flat head that will sit flush with the mounting tray. Great HDDs. I have much less trouble out of WD drives than Seagate.

I bought this drive to replace a failed HDD which on investigation did not have a good reliability record. WD offer a 5 year warrantee and claim this drive has a workload rating up to 550TB per year (among the highest of any 3.5-inch hard drive) with up to 2.5 million hours MTBF.

So far: Solid, fast. Downside: they're a bit loud. Being designed for datacenter use, they're optimised for speed not noise levels - so if you use it in a desktop you'll likely notice the noise when it's seeking.
