  • 1Description

Designed with home and small office/business customers in mind, the 2TB Red 5400 rpm SATA III 3.5" Internal NAS HDD from WD is well-suited for NAS environments with up to eight 3.5" drive bays. Engineered to handle increased workloads, this 2TB drive operates using a SATA III 6 Gb/s interface, a 64MB cache, and a rotational speed of 5400 rpm, all of which help to ensure uninterrupted data transfers with a sustained rate of up to 147 MB/s. This drive also features high levels of reliability, with 600,000 load/unload cycles, <10 in 1014 non-recoverable read errors per bits read, error recovery controls, and 1,000,000 hours MTBF for 1-8 bay NAS systems. Also built into this drive are noise and vibration protection and WD's NASware 3.0 helps increase system compatibility, allowing WD Red drives to be more easily integrated with your existing network infrastructure.

General Features

Fill Your NAS with WD Red
Built for 1 to 8-bay NAS systems, WD Red lets users store their data in one unit
NASware 3.0 Technology
Built into every WD Red hard drive, NASware 3.0's technology helps improves your system's storage performance by increasing compatibility, integration, upgradeability, and reliability
Built for NAS Compatibility
Desktop drives aren't purpose-built for NAS, but WD Red drives with NASware are. WD's technology helps takes the guesswork out of selecting a drive. WD Red is for small NAS systems and WD's algorithm balances performance and reliability in NAS and RAID environments
Desktop Drives vs. WD Red
Desktop hard drives are not designed for NAS environments. Do right by your NAS and choose a drive with an array of features to help preserve your data and maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS:
  • Compatibility: Without being tested for compatibility with your NAS system, improved performance is not guaranteed
  • Reliability: The always-on environment of a NAS or RAID is a hot one and desktop drives aren't typically tested in those conditions. WD Red is
  • Error Recovery Controls: WD Red NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system. Desktop drives are not typically designed for RAID environments where this can be an issue
  • Noise and Vibration Protection: Designed to operate solo, desktop drives offer little or no protection from the noise and vibration faced in a multi-drive system. WD Red drives are designed for multi-bay NAS systems
  • WD Red for Home
    Stream, backup, share, and organize your digital content at home with a NAS and WD Red drives designed to share content to the devices in your home. Red NASware helps increase your drives' compatibility with your devices, TV, stereo, and more
    WD Red for Small Business
    WD Red is a good hard drive choice for 1 to 8 bay systems. NASware 3.0 allows for integration with your existing network so WD Red can share and backup files at the speed of your business. For larger businesses with up to 16 bays, use WD Red Pro
    3D Active Balance Plus
    This helps ensure your data is protected from excessive vibration and noise in a NAS or RAID environment. This dual-plane balance control helps reduce the degradation of your drive over time
    Since your NAS system is always on, a reliable drive is essential. With an MTBF of up to 1 million hours, the WD Red drive with NASware 3.0 is designed for 24x7 environments
    Cooler Operations
    By reducing power consumption, the operating temperature of your NAS stays cooler. With a lower temperature in your system, you can create a more reliable solution for your NAS

    WD WD20EFRX reviews

    2TB Red 5400 rpm SATA III 3.5" Internal NAS HDD is rated 4.8 out of 5 by 107.
    Rated 4 out of 5 by from Good Network Drive I have a HP Windows Home Server which has been running without a major problem since 2008. I noticed some problems where I had to reboot the system recently, and I have an add-in program that reports a pre-failure warning on two of the drives, one being an original 500 Gb drive that has been running since installation in 2008! I replaced both these drives with the WD Red 2Tb drives, and so far they have been working without a hitch. Only time will tell how long they will last, and that is why the 4 star rating. Since these were formatted into the Window Home Server, I cannot comment on their built in software.

    Rated 5 out of 5 by from Great option for home NAS build I put 3 WD Red 2tb drives in a homebuilt NAS/Media server running 24/7. The server is running Ubuntu with a ZFS RaidZ pool. The drives are very quiet, run at low temps, and all worked fine out of the box. They arrived in very generic packaging, but were well padded and sealed in anti static bags. These drives are low power, 5400rpm. They will work fine in a desktop, but are geared toward low power/low temps/high reliability vs speed. The only caution about any advanced format drive used in a raid array, is to be aware that the drive reports 512b sectors while using 4k sectors. Just Google 4K drives and raid for more info on how to set them up for best performance in a raid array.

    Rated 5 out of 5 by from The best hard drives around... Period! I have been building computers for the past 22 years... Both professionally and for personal. The only hard drives that I will use are western digital. Every other manufacturers drives have failed one me, one way or another. Western Digital drives are without a doubt the most reliable. With that said, I bought these drives to use in my Netgear ReadyNAS server. It was time to upgrade my old NAS, which is also running WD drives (without issue). I chose these red drives because they are designed for servers. They are not the fastest RPMs or data transfer rate, but they are quiet and reliable. I would have gone with 4GB 7200rpm WDs, but the cost was prohibitive.

    Rated 5 out of 5 by from Assurance & Performance Did a lot of research to pick the Red's for my primary photography external drive to act as a RAID 1 setup in my (new) Newer Technology Guardian MAXimus Enclosure Q 2-Drive RAID 1. Use in a home office setup. Always have gone with Western Digital's and they have not disappointed in the past. They are energy efficient like the Green's, and go to standby as well. Takes about 10 sec. to become available after standby (you can hear them spool up on rpm), but not an issue if know to allow for slight delay. Also rated with faster transfer rates than the Green's. So far, so good.

    Rated 5 out of 5 by from Excellent choice for NAS applications If you are looking for a solid NAS drive look no further! If you are looking for an hd for a regular home computer go with a WD Green or something else. The reds are more expensive than the greens or other WD drives because they have some features that are only really utilized in large storage arrays. Just some food for thought. I currently have 5 or 6 of these WD reds in an UnRAID array that I use to store anything and everything in my house. They run cool and quiet with no fuss. I have some Western Digital drives (old greens, have not had the reds for more than a year or two) that are over 5+ years old in my NAS and they are all still running great with no bad SMART attributes or failures to date.

    Rated 5 out of 5 by from Replacing for NAS Have replaced many drives (mostly green series) with the Red series. Never any issues.

    Rated 4 out of 5 by from Soild choice & alot of storage WD still makes some of the best mechanical Hard drives on the market, and with the high cost of SSD drives . . . this drive may be slower to start-up and shutdown, but when you compare the cost per GB of storage, it's not a bad choice even today. With a 5 year warranty and much lower cost, you may be able to afford spending a few extra minutes of time while working with your computer. I didn't rate it a 5 start only because of the fact that it is mechanical and not solid state.

    Rated 5 out of 5 by from cool running drives I used these in my Windows Home Server replacing WD 1TB Black drives that are 2+ years old. the Black drives were running very hot and were tripping a S.M.A.R.T. Temperature Warning over 70C. 2 weeks in and the drives are Purring along and running at a sustainable 36C. there were no problems with the purhcase through installation. Great Vlaue.
