Summary: Don't let the 5900rpm make you second guess your decision like it did for me. These drives are more than adequate for speed. I got two of these and put them into Raid 1 after installing the OpenSuse operating system. They run as good as can be.
Summary: I have eight of these now, with four in a NAS and four in a workstation, and they are all going strong. I used normal 3TB Seagate drives in a raid 5 array, and they started dropping out of the array after about a year, so it seems a NAS grade/type drive or higher is essential for a stable RAID...
NOT compatible with Netgear ReadyNAS (or so they say?)
1 January 2015
Summary: Good specs, but NOT compatible with Netgear's ReadyNAS 104. Yes, it IS on Netgear's compatible drives list for that unit, but tech support *insists* it is not compatible. Ask for Hanna at Netgear support for details. (FYI. I do not agree, I wasn't impressed by her technical prowess).
Summary: So far so good. I usually buy WD but this one had great reviews and the price was right. What else can I say. It is working fine in a OWC dual drive bay via Firewire 800 to a 2010 Mac Pro. No issues!
Summary: I bought two of these in July. They were working well except one would disappear from the OS on very rare occasions so I changed SATA cables and it seemed fine. Five months later, within two weeks both stopped working while my other HDD in the PC was fine.
Summary: I am only giving this three stars initially because it's new and, as with so many things, its real value will only be determined over the long haul (I'm quite tired of replacing failed drives).
Summary: I got these for my media/file server. Before this, I was using Seagate Greens in a software RAID, they kept dropping out of the RAID, and reporting SMART failure. I tested them all after replacing them with these NAS drives, and they all appear to be fine.
Summary: I have been running these drives for about 6 months now without any issues. I set them up in a RAID 1 array and achieve 100MB/s over my network. I will never understand why people use non-NAS drives and in NAS arrays and wonder why they have failures.
