Quiet and reliable built-in (internal) 3.5" form factor hard drive from the 2020 model WD Red HDD family. This line includes SATA3 drives with capacities ranging from 1 GB to 14 TB, whose firmware and design are optimized for long-term data storage tasks in NAS arrays. Such hard drives are adapted for use in SOHO NAS (small office/home office), are compatible with almost all modern file storage models, and are characterized by an impressive operational resource.
The WD NasWare Red WD40EFRX hard drive is positioned as a mid-price category product intended for use in home and office storage (up to 8 drives), connected to a local network via high-speed network cables or wireless connections. This model uses classic magnetic recording technology CMR, which allows for an enhanced data transfer speed, and the magnetic platters themselves rotate at a speed of 5400 rpm.
This ensures moderate heat dissipation (4.5W), which is important for creating multi-disk home NAS systems with quiet cooling. It can also be used as an additional HDD drive in a home PC, gaming, or multimedia system. It is not recommended for use as a system drive, but it is excellent for storing large volumes of work project files, video, photo, and high-quality audio content, as well as backups.
Always clarify the specifications and configuration of the product with the online store manager before purchasing.

Two 4TB drives in a zero RAID, I expected much more in terms of performance. After a year, one failed. The old 1TB Seagate with PS works faster. It's hard to say, I bought it because of its former glory, but I was wrong. Questionable reliability  Valeriy Proshkin: use WD WD40EFRX more than year |
2TB model - quiet, cool, reliable, 10 units in operation - 2 have already accumulated over 20,000 hours, the entire surface of the disks is good, with fast access time 4TB model - quiet in standby, barely audible in operation, warm 8TB model - quiet in standby, clearly audible in operation, hot up to 52 degrees 2TB model - quiet, cool, reliable 4TB model - quiet in standby, slightly audible in operation, warm 8TB model - quiet in standby, clearly audible in operation, fast 8TB model and above - the main drawback is helium, it is not eternal and constantly dissipates through the case. Unsuitable for "eternal" storage. |
good quality product I think the main advantage is that it is optimized for consumer NAS. They behave normally at work and remain cool. This is a very good indicator. This model is cheaper than buying the RE series. They are more reliable in operation than desktop models. not found Andrey: use WD WD10EFRX week |
