Product Information

All information about the Western Digital WD40EFRX hard disk drive: technical parameters, failure symptoms, free asked questions, reviews, HDD repair and data recovery. BTW, if you ask WD how to know the DRIVE MODEL inside an external WD enclosure, they will tell you it’s impossible! KD Mann you mean to blame the 15+ year old storage platform with millions of installations instead of the company that marketed those drives as suitable for ZFS?

Do I need an expensive CMR (Ironwolf Helium), a “cheaper” SMR Red NAS drive or will a standard barracuda 8TB SMR “Archive Drive suffice”, for Media (Plex) and Photos. Still, this is a good indicator of the drive working through its internal data management processes and impacting performance. For those googling for the answer whether combining WD EFRX and WDEFZX (WD40EFRX and WD40EFZX in my case) would be safe. Things get worse when Steam needs to preallocate storage space for new games, often I have to leave the machine alone for two to three hours.On average less platters/heads means better reliability (less things that can fail), so the 68N32N0 should be a better drive overall. With that said, all of the tested drives were disconnected as soon as their previous benchmarks were complete, and before plugging them back in for use in our test NAS array. They are also not doing a realistic test since it seems they are not putting a workload on the NAS during rebuilds? Absent that context, simply putting the word “SMR” in a product listing does not help an uninformed purchaser choose the correct product.

The performance results achieved by the WD Red WD40EFAX surprised me; my only personal experience with SMR drives prior to this point was with Seagate’s Archive line. I actually have a similar problem with a My Cloud EX2 Ultra NAS with drive 2 being (SMART) reported as in impending Fail state.The performance of the drive seemed to recover relatively quickly if given even brief periods of inactivity. I work over 20 years with computers and during this time NO drive has failed (had had at least 5,6 PCs/laptops) excluding these aforementioned super-bulletproof-high-performance-mega-NAS-drives.

During this time, scrubs were disabled for the pool and resilvering priority was completely disabled.

Unfortunately, while the SMR WD Red performed respectably in the previous benchmarks, the RAIDZ resilver test proved to be another matter entirely. I have also tracked my Red drives statistics from the beginning but after 2000 power on hours or so they were no longer showing the same running hours.If you are reading this piece, and know someone who uses, or may use WD Red drives in NAS arrays but may not keep track of trends, send them this article, a chart from it, or the video. Ultimately, the Western Digital Red SATA III with NCQ support is a much more professional solution for 24-hour continuous operation than classic desktop and notebook hard drives, which of course were not designed and tested for these conditions. But, selling SMR as a NAS drive, AND not clearly labeling it, (like Red Lite), that should be criminal.
