Used to replace two WD Red drives which failed in a 4 bay NAS within a couple days of each other. Now have a mix of drives and these seem to be OK.

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..

Where is the NAS. This is just a hard disc.

Have had this drive installed in a ShareCentre for over two weeks now, it's blazing fast and so far reliable, and have had no problems at all.

I purchased four of these for my QNAP NAS and within a few hours one was dead. So much for reliability.

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.

Though it doesn't perform like a standard drive suitable to be paired with an OS for your primary use, but has all the near-enterprise functionality of a NAS good enough for SOHO use. Best part is that its able to keep up with WD Red 2TB version. Not bad for a 4TB counterpart from Seagate!

Back in July of last year, Western Digital launched the first purpose built NAS hard drive, and for the longest time I was waiting for Seagate to do the same. Today this has come to fruition with the NAS HDD, offered in two, three and four TB capacities.

With the lower rotational speed (5400 RMP if I recall) I was not expecting these drives to be speed demons, but they actually have just as good or better transfer rate to the 7200 RPM drives on sequential transfers, which is mostly what I do.

The biggest plus for me has been the low temperatures and low power consumption; I originally setup a NAS using the Seagate Desktop drives that are 7200 RPM drives; They put off some real heat; I had to upgrade the fans in my NAS to keep them cool.

All Seagate drives give "Raw Read Error" information in the SMART status that makes the drives look like they will croak any second; I have seen it from Seagate Constellation, Seagate Desktop and in these Seagate NAS drives; I am not a big fan of that, but it is to be expected of any Seagate.
