Great product as always from Seagate. Excellent price and come with 5 years warranty.If you register with Seagate you can get data recovery service for 14 bucks if anything ever happens to your drive no matter what.

The arena for NAS-targeted hard drives has just welcomed a second combatant: Seagate's "NAS HDD". Like WD's Red series, NAS HDD is designed to work well with RAID controllers, has improved vibration-reduction, and additional power profiles. Unlike WD's Red, NAS HDD has a 4TB model.

Fantastic performance for a ~5,900 RPM hard drive; Only 4TB option for NAS-specific models (your move; WD); 3-year warranty

A bit more expensive than WD's Red (2TB and 3TB). Seagate's drives are newer; pricing will go down

The Seagate NAS HDD is a 3.5" form factor, 6Gb/s SATA interface hard drive that spins at 5,900RPM, ranges up to 4TB in capacity and is specifically engineered to be installed in one to five-bay NAS devices.

Higher mixed workload and sequential throughput than WD Red; Greatest capacity in NAS HDD segment; Better latency consistency in mixed workloads than WD Red

Back of the group random 4k max latency in write activity

When QNAP sent over the TS-559 Pro+ to us for review in September 2010, I decided it was a wise choice to buy a new set of hard drives to go along with the NAS. My requirements were simple; I wanted something reasonably power efficient, reasonably fast, and reasonably priced to run in RAID 5.

With the NAS HDD series, Seagate now has hard disks that are optimised for use in NAS devices just like the Western Digital Red disks. The fact that they're in TLER mode by default is important for NAS devices, and it's also positive that Seagate tests the disks with all the major NAS devices.
