Toshiba N300 PRO 12TB Large-Sized Business NAS (up to 24 bays) 3.5-Inch Internal Hard Drive - Up to 300 TB/year Workload Rate CMR SATA 6 GB/s 7200 RPM 512 MB Cache - HDWG51CXZSTB

This is the standard drive I use in most of my NAS devices. We have a dozen users who use files on the NAS 16 hours a day, 7 days a week and these drives hold up well. In the past five years, out of 24 drives, I have only had 1 fail. I have tried other brands in the past with slightly worse stats. Note: Toshiba manufactures many other brands as well.

The Drive is dead on arrival. I've spent a few nights troubleshooting it in different ports and PC's, just wasted my time.

Great packaging, and the drive is still going strong 1 year later. Will order more

I ordered 5 N300 Pro (14tb) to use in a NAS. It surprised me how quiet the drives are and how cool they run. So far most of my time has only been spent rebuilding the storage pool, but I'm happy with the drives and their cool running temps. Granted my NAS is not very beefy in terms of hardware, but temps and noise is comparable to my old 4TB WD100EFAX drives. All drives passed the extended SMART test. Regarding the warranty, what other folks said is true, I checked my drives and they all showed NO WARRANTY on the Toshiba site. But with that said, I also bought some 6TB WD drives from Amazon as spares for another NAS and those also show "NO LIMITED WARRANY" on the WD site, same boat there.

Got a couple of these for my network storage. They are quiet, have a large storage capacity, and was easy to install. They run at a higher RPM then what would be used in a desktop computer so they have a great read / write speed.
