Review: Fully met my expectations. Excellent NAS drive for RAID - The WD 1TB WDBMMA0010HNC-NRSN drive kit fully met my expectations. I bought this drive 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 or issues. 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 desertcart 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. They ran great and I had no complaints over several days of use. This isn't too surprising as many NAS boxes use little Intel Atom processors. Next I did a comparison by replacing the WD Red drives with WD Black 750GB drives I had on the shelf. I didn't see much difference but I felt that copies of lots of small/medium files completed more quickly with the Red drives. Maybe the caching algorithm of drive was just better tuned for NAS on the Red drives. A plus is the Time Limited Error Recovery (TLER) which is an important part of drives that are designed for RAID deployment. And having a drive that is designed to be on 24X7 is great. I've switched back to the WD Red drives in my home-built NAS and I'll update this review as I live with the drives and report if there are any problems or notable excellence that stands out. Hope this bit of experience helps someone. Update: Dec 3, 2013 I have recently gotten a Buffalo LinkStation 420 2TB 2-DriveNAS Personal Cloud Storage and Media Server In comparing my home built FreeNAS system (on old core duo hardware) with two of these drives to the LinkStation with 2 Toshiba drives was interesting. The FreeNAS system with the WD NAS drives (both systems with RAID1) ran about 50% faster than the LinkStation. You can check my review on the LinkStation for more information about my comparison. The LinkStation might be a better option to get diskless for a very low price use these drives inside it. The small footprint and low power make it an attractive option. Bottom-line it seems there may be something to the NAS specific firmware of these drives.
Review: Good drive poor shipping - Good drive. Poor shipping. The drive itself works fine. However the shipping was terrible. I ordered two 4T drives and a NAS. It took 2 weeks to arrive then one of those drives was damaged and in operable. I returned it and order another. The replacement came 3 weeks later. Just in original packaging with no over box or padding. Lucky this one worked but could have been damaged easily the way it was shipped. Definitely not what i expected from an desertcart retailer.

## Questions & Answers

**Q: Is this WD Red drive backed by WD's 3-year limited warranty? I don't see it in the product description.**
A: I had an issue with some of the WD Red drives I had purchased through Amazon...
I had a failure and contacted WD for replacement under warranty...  
I was told that the drive I had only had a one year warranty period not the three year.
The drive serial number started with WD and that indicated it was a drive from a single disk NAS..  those have only a one year warranty
Where the other drives carry the 3 year.  
What is the difference in the drives i can not say or tell from looking at them and no other information was provided by WD.
I was told I needed to go back to the seller and see if they would fix the issue.
Since I've bought a number of drives over the last three years one at a time and registered them with WD, I didn't mark each drive and could not tell which drive came from what seller since the invoices didn't indicate the serial number of the drives..   I have 4 other drives in that situation. Since it was registered at the time I received the drive I know it was within the 3 years but after the 1 year warranty that WD would support.  I had to buy a replacement..  Thing is that all the drive were in WD boxes and sealed in static bags.

**Q: Can this drive be installed into an external HD case and used as a single drive media server or does it have to be installed in a NAS case?**
A: It's designed for continuous use and not intended to be shut down and restarted on a routine basis.  Those that say that they lack the performance of a desktop HD is just not true. they have similar performance characteristics with most 5200 RPM drives. One typically doesn't put a 4TB drive in a PC as a system drive. Usually, you would use a 1 TB drive that are typically 7200 RPM, which does provide better performance. If you really need that much space  in your PC (system or otherwise) you're better off not using a NAS drive, something like the Seagate Barracuda.

**Q: Why is this more expensive than an external wd 10 tb drive such as: https://www.amazon.com/s?k=wd+10tb+elements+desktop+usb+3.0+external+hard+drive&re**
A: The retail storage market is more competitive. NAS and Enterprise drives meet 24/7/365 read write reliability benchmarks and typically have a 3-5 year warranty. Retail consumer drives may in some cases last as long as NAS drives, but typically will have a shorter warranty. Note that liberating a hard drive from a retail external enclosure (to use in a PC) would likely void the drives warranty altogether.

**Q: Can this drive be used to replace the internal hard drive within the apple 3tb time capsule?**
A: Depends if it uses a 2.5in or 3.5inch drive or not. Specs are probably fine but need to know what size of hard drive it takes. Based on the dimensions of the apple device, it might accommodate this. Based on the apple dimensions, I would be surprised if it uses 3.5in drives but it isn't impossible.

### ⭐⭐⭐⭐⭐ Works great for a home NAS
*by B***D on December 3, 2025*

I rebuilt a failing TrueNAS server using four of these in a RAIDZ1. I'm using 2.5Gbps and the drives are plenty fast for a couple of file shares and as storage for a small home Proxmox cluster. They run cool and consistent between 22 and 31 degrees Celsius with minimal direct cooling. Do yourself a favor and label the drives with the SNs so you can easily identify a drive when one fails. I bought these to replace 6 year old WD Reds so they should be reliable and good for the price.
