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.

Got this for $158.88 from another chain clearance sale. Seagate has the Ironwolf series replacing this. Works fine in my DS413.

Works with my Synology

I needed to expand the capacity of my 500GB Buffalo Linkstation NAS and this drive was a perfect choice. We have two of this drives as a backup RAID at my work place and they perform flawless. The drive is quiet, cool and designed for being reliable storage. I also got a great deal on it!

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.

I installed them in a Seagate NAS unit running Windows Storage Server 2012. They are fast and have performed flawlessly in a disk pool for almost 2 years.

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.

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

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...

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

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
