This is for an NAS set-up, and it worked well for that.

Size Name: 1 TB Vine Customer Review of Free Product ( What's this? )
The WD 1TB WDBMMA0010HNC-NRSN drive kit fully met my expectations. I got this drive through the Vine program and I bought a second to make a RAID1 pair. The drive performed well in my home-built FreeNAS server and provided better network storage performance than expected without any glitches.

When compared with 750GB WD Black drives in the same server the RED drives appeared to give slightly better perforance in NAS. Maybe the NAS specific firmware isn't just marketing.

For more, read on...

I wanted to build a NAS server for windows sharing, iSCSI, and nfs sharing. I had an old 1U "pizza box" server with a core 2 dual CPU and 4GB of ram available plus SATA II (300MBPS) channels. I got one of the WDBMMA0010HNC-NRSN WD-red drives through the vine programs and I bought a second through Amazon to build this NAS server.

This drive is the retail package. It came in a nice box with 4 screws for mounting and a little bit of very fine printed material which I didn't bother to read. If a "bare drive" is fine and you don't care about packaging you might want to consider another listing for the 1TB WD Red drives which may be at a lower price for essentially the same thing.

The software I used to drive the NAS is the excellent (especially at the price) FreeNAS server. It installs on a USB stick of at least 2GB. My old box had several USB 2.1 ports, so no problem. I configured the drives in a RAID 1 mirrored array using software RAID (instead of the FRAID (fake raid) built into the motherboard chip set.

I first built the server with the WD Red drives first and ran some casual tests with windows shares and iSCSI. Using windows network or iSCSI I could saturate my Gigabit Ethernet with no problem. Performance was not an issue.

Size Name: 1 TB Vine Customer Review of Free Product ( What's this? )
In general I've good luck with Western Digital hard drives, and this one was no exception. Storage keeps getting cheaper, drives keep getting bigger, but performance seems to stay stable. I use this as a normal drive, not NAS. I plugged it into the cables inside my computer, booted up, the computer (Windows 7) recognized it and installed the correct driver. A little fuss with the device manager and I was good to go. It's quiet and has been running fine, no issues. Definitely worth your consideration.

Size Name: 1 TB Vine Customer Review of Free Product ( What's this? )
Western Digital deserves praise for offering application-optimized hard disk drives, though I think they could do a much better job explaining what kinds of optimizations were done to make certain drives better suited for certain situations than others. The optimizations are tangible, though the differences in specs between drive families and sometimes even within the same family can be subtle, so having more information would be appreciated.

This drive, a WD Network, is optimized for NAS duty. While similar to WD Red, WD Network is consumer oriented and features different firmware (WD Red has NASWare 2.0, WD Network has NASWare...I honestly don't know how they're different) and WD Red are rated for 600,000 load/unload cycles whereas WD Network does not specify a rating. (They both share the same 1,000,000 hour MTBF.)

How are NAS drives different from Desktop ones? In a nutshell, NAS drives should be better balanced to minimize vibration, more tolerant of shock during operation, quieter, consume less power for reduced heat output, rated for operation at higher temperatures, and are generally lower performing but more reliable.

I ran this 1TB WD Network drive in my work PC and a 4-drive NAS for this review. From my own testing, I can confirm that the WD Network ran cool and quiet and it performed rather well for sequential read/writes, though it suffered from higher latency compared to a 7200 RPM desktop drive. From a vibration perspective, whatever WD did with the Network drives, it seems to have worked. I performed an unscientific "finger test" and felt a few different drives in operation, and indeed the WD Network seemed to vibrate the least when compared to a WD Black 750GB and a Seagate 7200.14 500GB I had access to.

Size Name: 1 TB Vine Customer Review of Free Product ( What's this? )
Instead of a NAS, I am using this in my home-built custom PC desktop. It works great. Lots of space, sufficient speed, and it was easy to install. I did need to use Partition Magic to format the drive as NTFS for my system, but now it's humming along happily, serving as a media repository.

The packaging was typical WD stuff, but it served its purpose of protecting the hard drive for shipment.

It doesn't seem to have added too much in terms of heat to my PC, either. As for durability, I've only had it for a while so I can't assess that yet, but I suspect WD isn't overstating their claims of durability. This will probably be overkill for a desktop system.

All told, I'm happy with this hard drive. It's going to be a great place to store my media.

There isn't a lot to say about the Western Digital 1 TB 3.5-inch hard drive. It's dependable and works well. I've had no issues with it. It comes with a 3-year warranty, is designed for NAS systems with up to 5 bays, and runs cool and quiet. It performs well and does exactly what I want my hard drive to do - work!
