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: Solid NAS drive, no complaints at all - Threw this in my home server build and it detected immediately on the first boot with zero issues. Been running it for months now and temperatures look fine, no weird sounds, totally stable. If you are setting up a RAID array this is the obvious pick since the NAS specific firmware actually matters and is not just marketing. ## Features - Available in capacities ranging from 1-14TB(1) with support for up to 8 bays | (1) 1MB = 1 million bytes, 1GB = 1 billion bytes, and 1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment.Specific uses: NAS,Business - Supports up to 180 TB/yr workload rate(2) | (2) Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred βœ• (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations. - NASware firmware for compatibility - Built for small or medium business NAS systems in a 24/7 environment - 3-year limited warranty(3) | (3) MTBF specifications are based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions: workload of 90TB/year and drive temperature of 40Β°C. Derating of MTBF will occur above these parameters, up to 65Β°C drive temperature. MTBF does not predict an individual drive’s reliability and does not constitute a warranty. Not all products may be available in all regions of the world. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BDXSK2K7 | | Additional Features | Portable | | Best Sellers Rank | #7 in Internal Hard Drives | | Brand | WD | | Built-In Media | Internal Hard Drive | | Cache Memory Installed Size | 4 | | Color | Red | | Compatible Devices | NAS System | | Connectivity Technology | SATA | | Customer Reviews | 4.5 out of 5 stars 9,553 Reviews | | Digital Storage Capacity | 4 TB | | Enclosure Material | Information Not Available | | Form Factor | 3.5-inch | | Global Trade Identification Number | 00718037899794 | | Hard Disk Description | Mechanical Hard Disk | | Hard Disk Form Factor | 3.5 Inches | | Hard Disk Interface | Serial ATA-600 | | Hard Disk Rotational Speed | 5400 RPM | | Hard-Drive Size | 4 TB | | Hardware Connectivity | SATA 6.0 Gb/s | | Installation Type | Internal Hard Drive | | Item Dimensions L x W x Thickness | 5.79"L x 4"W x 1.03"Th | | Item Type Name | Internal Hard Drive | | Item Weight | 570 Grams | | Manufacturer | Western Digital Technologies, Inc. | | Mfr Part Number | WD40EFPX | | Model Name | Red Plus | | Model Number | WD40EFPX | | Number of Items | 1 | | Read Speed | 150 Megabytes Per Second | | Special Feature | Portable | | Specific Uses For Product | Business, NAS | | UPC | 718037899794 | | Unit Count | 1.0 Count | | Warranty Description | 3 years limited warranty | ## Product Details - **Brand:** WD - **Color:** Red - **Compatible Devices:** NAS System - **Connectivity Technology:** SATA - **Digital Storage Capacity:** 4 TB - **Hard Disk Description:** Mechanical Hard Disk - **Hard Disk Form Factor:** 3.5 Inches - **Hard Disk Interface:** Serial ATA-600 - **Installation Type:** Internal Hard Drive - **Special Feature:** Portable ## Images ![Western Digital 4TB WD Red Plus NAS Internal Hard Drive HDD - 5400 RPM, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5" -WD40EFPX - Image 1](https://m.media-amazon.com/images/I/81wgF5tXOJL.jpg) ## Available Options This product comes in different **Size, Style** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fully met my expectations.
