WD WD40EFRX overview

  • 1Description

Designed with home and small office/business customers in mind, the 4TB 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 4TB 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 150 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
    Reliability
    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 WD40EFRX reviews

    4TB Red 5400 rpm SATA III 3.5" Internal NAS HDD is rated 4.6 out of 5 by 144.
    Rated 1 out of 5 by from Hard Drive failed after 4 months Bought two of these drive for my Synology NAS. One drive failed after four months. I had to pay to ship my brand new failed drive back to WD. Took two weeks to get a replacement. Meant I had to buy another hdd to protect my data while waiting for a replacement. Failed on Christmas eve. Holidays lost because I had to backup my data to my old external HDDs.

    Rated 5 out of 5 by from I will purchase again when I expand my nas I have always had good luck with WD Hdd's, they work as expected. I have been a cto and senior service engineer on network deployments for the last 40 years (using many different vendor drives) and have used lots of WD enterprise, datacenter and nas drives for equipment build outs for various customers environments. These red, nas rated drives for smaller raid systems are a great price and just plain work. I also over the years have had to use WD support for RMA's on a couple failed drives. WD has been easy to work with and provide a prompt replacement. Just make sure you register the drives when placed in service.
    Date published: 2017-03-06
    Rated 5 out of 5 by from Solid choice for NAS Photographers no longer buy film, they buy hard drives. I've been using WD as my preferred drive for over 4 years, with over 50 deployed in that time. WD drives are consistently rated as quality drives in studies like the one Blackblaze has done. Their longevity numbers line up with my experience. All drives die, and even some new drives die. That's why you need a good RAID for fault tolerant storage. Expect that drives will fail, and keep a couple spares on hand so you can rebuild your RAID quickly. And don't forget a backup. RAID is not a backup. Three copies is the best practice, with offsite storage. I retire my old drives from my RAID at about 24,000 hours usage, and then use them for backup where they are rarely used. Rotating your drives as they age helps head off problems.
    Date published: 2014-08-07
    Rated 4 out of 5 by from Designed for 24x7 Storage Arrays These drives are designed for the small storage arrays most commonly used in homes and small businesses. They are intended to consume less power and dissipate less heat than performance drives, and to have better longevity in a 24x7 environment, but at a lower price than the industrial-grade (enterprise) drives used in larger storage arrays typically deployed in a machine-room environment. The power and heat savings apparently are achieved by running the spindles at a relatively low speed. Western Digital doesn't publish the specs (at least, I couldn't find them), but it's likely they spin at or slightly above 5400 rpmlike the disks typically installed in laptopsand below the 7200 rpm or faster drives that are intended to pump out data as quickly as possible. The longevity claims reportedly are based on the fact that the drives don't park the heads, which is desirable in any 24x7 environment, and some form of vibration dampening similer (if perhsps not quite as aggressive) to that found in industrial-grade drives. The drives certainly run quietno doubt because of the low spindle speed and perhaps because of the vibration dampening. I'm using several of these in a 5-bay consumer-grade network-attached storage array, and while I haven't done any rigorous performance testing, I don't think the higher rotational latency is costing me much, if anything, in reduced performance; in an NAS environment, other factors are more likely to dominate performance than how fast the disks are spinning. I've only had these installed for a couple of weeks and can't comment on how well they will stand up over time, but they carry a three-year warranty and the features that are supposed to make these drives particularly suitable for 24x7 use definitely make sense.

    Rated 4 out of 5 by from Drives for 24x7 Use I keep buying these drives, and haven't had one die on me yet. Western Digital's Red product line is designed for systems which must run 24x7: general-purpose servers and dedicated storage appliances where reliability and long-life are more important than high performance. They don't consume as much power as faster drives, and therefore run cooler. I recently purchased four of the 4TB and two of the 1TB drives to use in a pair of redundant compact servers that I use to store and serve digital media, as well as for some general-purpose computing; their performance is more than adequate for these purposes and the three-year warranty attests to WD's confidence in their reliability.

    Rated 4 out of 5 by from Used in NAS Storage Unit These drives were setup in a RAID 1 configuration in an Asustor Network Attached Storage system that is being used as an iTunes server and photo storage system. The NAS serves verious Sonos devices throughout the house. Inserting the drives into the NAS was easy. Startup was easy. And the drives have worked well so far (it's only been a couple of weeks). There was nothing special required to mate the drives and the NAS device. The only complaint I have is that when the drives are really busy, it can be a bit noisy. Setting the NAS unit on a soft base helps control the noise levels.
    Date published: 2015-04-26
    Rated 4 out of 5 by from Great Drives for NAS We installed 4 of these drive into a NAS RAID 5 array. So far they have performed wonderfully. Once inside the inclosed the drives are relatively quite. Read and write times appear to be more of an issue with our NAS unit than the drives themselves. Obviously they will never achieve speeds like that of SSD's but as mechanical drives they work really well. Only complaint is the packaging. They don't seam well protected from shock. Not a B&H issue at all this is more the manufacture just being cheap. In fact the B&H packing of the box the drives came in had way better protection.
