Toshiba N300 PRO 18TB 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 - HDWG51JXZSTB

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.

Bought these when the price dropped as a lower cost option to the same size WD Red Pro drives.. They have proven to be reliable - so far, with all units surviving 72 hours burn in and several more days of moving terabytes of data too/from these drives. I will buy more when needed.
