Reliability

WD40EFAX drive is a great drive for 24x7 operation in NAS systems.  I have owned a WD MyCloud EX4100 (4-bay) NAS for about 5 years now and have only had one drive degrade to the point I needed to replace one disk.  After replacing the faulty drive the NAS rebuilt the RAID configuration and I never lost any data.  I subsequently purchased a spare WD40EFAX drive in case of another failure.
I highly recommend these drive.  They are extremely reliable in constant operations.

Western Digital Drives for NAS

Western Digital

The 6tb drives slipped easily into my NAS. They've worked perfectly since.

6TB Red

A solid, reliable disk. I set it up over a network and clone our drives to it via Carbon Copy Cloner. It works and I don't even question it.

Reliable, affordable

I got them for my NAS. All the drives were shipped at once and arrived quickly and in good condition. All of them installed perfectly and have been working great, 24/7 for the past few months without a single issue.

Good Hard Drives For The NAS

Have been using WD drives since the early days of the desktop PC. I have always found them to be reliable and a good value. Am using this particular drive model in a 4-drive array.

Reliable & a Good Value

My MyCloud runs continuously for years. I replaced one drive last year with a new WD40EFAX. It was a simple procedure and the MyCloud quickly mirrored the good drive onto the new one. Has been running about six months with nary a hiccup.

Quick replacement of one-half MyCloud Mirror

Hard to rate a new drive. Purchased these two drives because I had one fail, while still under warranty, and I think I'm talking to a chatbox, who won't send me an RMA as promised over a month ago. But the failed drive is a replacement for a MyCloud Ultra II device that failed while still under warranty, which was a replacement for an out of warranty MyCloud device that lasted for about five years.

Replacement for Replacement

Four 6T drives were purchased in May 2019 for use in a NAS box.  Two of the original four still function. One failed for unrecoverable sector errors in August 2021.  A second failed in September 2021 ... disk would spin but not ID.

Reliability could use some attention

I purchasd 2 hard drives (4 TB)  in 2021 for the Open Media Vault NAS. One hard drive stopped working in 2023 (and NAS was not production, just waiting on a shelf). Then another hard drive degraded in 2024. The motor starts spinning and then stops every 8-10 seconds. As a result, ETC of resyncing 4 TB parralel RAID  massive is 128 hours or 5 days! This is a disaster! Both hard drives were manufactured on August 2021). My older hard drives (the oldest one manifatured in 2007) are still alive.

Very Unreliable Hard Drives. Two Failures in a Raw

When installed, it issue the message RAID Degraded
