A quick and capacious hard disk drive, we think the Seagate NAS HDD 4TB would be good for desktop NAS- and RAID use. Here's our full Seagate NAS HDD 4TB review, with benchmarks.

I've got a few of them in a custom Linux-based NAS built in a Norco 4220 case, mixed with many other drives of varying capacity and speed. They run cool and perform consistently.

Lots of capacity Is happy running in a dense install with many other drives

Poor random IO performance - its not designed for that usage

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.

This disk runs so quiet you don't know it is on. Superb.

We got all HDD as faulty one.. the packing was in worst form. When I contacted with the seller, they reverted us in negative and asked us to talk with SnapDeal... Very poor service..

Got the Seagate NAS 4 tb and I am pleased, seems to work well and is compatable with all NAS based systems. I am a little wary that the product came packaged in a NON-SEALED brown cardboard box like when I install a dozen or so of NAS based drives, and that purchasing in other retails store also...

Seagate my make of choice, bought 4 of these for a NAS and they are very quiet, set up as RAID 5, all drives individually packed to offer very good protection during delivery, would recommend

Bought 2 of these for my new NAS and the difference between these 2 and my old 1's is amazing - far quieter. definitely recommended and I plan to get 2 higher capacity 1's in the future to complement the 2 I already have.

NetGear doesn't have many 4TB drives approved for use with m ReadyNAS Ultra 4. This was the most cost-effective one. Plugged right in, works just fine. Large capacity, good price, quiet, fast.
