Western Digital 10TB WD Red NAS Internal Hard Drive – 5400 RPM Class, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5″ – WD100EFAX (Old Version)

Another solid drive from WD
I placed one of these in a 4-bay Synology NAS (DS418) with some smaller drives. I’ll add more 10 TB drives later. It has only been a few weeks, but I have run an extended SMART test, rebuilt my raid volume from 3 drives to 4, and backed up several terabytes of data at nearly the speed capacity of my gigabit network. No problems.I gave it a 4 on noise level. It doesn’t bother me, but you can easily hear the heads moving in a quiet room. Some people would be bothered, but most would not. A drive engineer once told me that if they make them too quiet people complain because they can’t tell when the drive is working!I see that Amazon has stopped selling these directly. I tried to buy through them, but they kept sending the wrong product. I went to another vendor, and got what I needed on the first try.

Great, quiet NAS hard drive
Purchased two 10TB drives during Prime Day (for under $216 each) in July ’19 to go into a Synology 1019+ (bought at the same time). I also bought two of the drives from another vendor (for the same price). Had to split the order as both Amazon and the other vendor had a two drive limit, which is a bit odd for NAS drives which are usually bought in multiple units. Anyway, it let more than one vendor get in on the sale. Keeping an eye out now for one more to fill the last drive bay.Started out with two drives in SHR1 (one drive fault tolerance). It took about three days for the NAS to initialize them. The second two drives arrived, I put them in and told the NAS to switch to SHR2 (two drive fault tolerance). Eight days later, I’m 40% through initializing the second drive! The good thing is that this conversion should give the drives a good initial workout.So far, no bad sectors. The drives run at about 35C / 95F in a room that is about 75F. Drives are nice and quiet. I can hear the usual hard drive clucking sounds if I’m right next to it, but from six feet away there is no sound. Hopefully the drives hold up and I’ll update the review if any issues come up.Only complaint is that it would be nice if there was a more comprehensive test suite like the Seagate Iron Wolf drives, which Synology can access directly.

Great experience & reliable drive
Purchased in July, used for 6 months to assess the product and performance before writing a review. The purchase experience with All4Computers was flawless, the drive was delivered on time and well packaged. In 6 months of use the drive operated reliabilty with no problems whatsoever. Would recommended doing business with All4Computers again !

Tres beau disque. Vitesse de transfert presque double par rapport a mes anciens red ou purple. 190Mo/s en lecture comme ecriture. Il est 2 a 3 degres plus chaud que mes anciens et genere un peu plus de bruit, tres peu. Pas des bruits de rotation, plutot des bruit de tete. Surement l’ajustement de apm.

I’ve had very good luck with WD Red drives over the years in terms of reliability.I’ve currently got 6 x 4TB (4 of which are in a RAID 5 array), 2 x 8TB, and 2 x 10TB. I’ve had a number of 2TB drives as well. All have performed very well.- Very reliable drives- Low power consumption- Operates at low temperatures- Quiet operationDrive comparison:10TB: 256MB cache, 210 MB/s sequential performance*8TB: 128MB cache, 178 MB/s sequential performance6TB: 64MB cache, 175 MB/s sequential performance1-4TB: 64MB cache, ~150 MB/s sequential performance*The 8TB sold here (model WD80EFZX) has a 128MB cache, but it’s worth noting that there’s other versions of this drive (models WD80EFAX and WD80EMAZ) which have a 256MB cache.The 8TB/10TB models use a sealed helium chamber to reduce platter friction — HGST developed the technology for their expensive enterprise drives and WD acquired this technology when they purchased HGST. WD has now implemented it in the consumer space relatively unchanged but at roughly a fifth of the cost.(I’ve had a number of Seagate drives in the past as well but I’ll never buy another Seagate product as most of my Seagate drives failed rather miserably, including 2 in a RAID 5 array which failed almost simultaneously, resulting in the loss of a lot of important data. A couple of years ago Backblaze noted that their Seagate drives had a 73.5% survival rate over 36 months, with a burst of deaths near the 20 month mark. Their WD drives had a 94.8% survival rate over the same period — i.e. the WD drives were 5x less likely to fail within the first 3 years when compared to Seagate.)My biggest gripe is actually unrelated to the product itself but with Amazon’s limit of 1 drive per customer — this really makes no sense for NAS drives seeing as most people will need 2-4 of them. To use an audio analogy, this would be like having a limit of 1 speaker or 1 DJ turntable per customer… pretty silly.(EDIT: I can confirm that you’re able to reorder after exactly 7 days.)While not specific to this drive, I strongly recommend doing an ‘Extended Scan’ on all new HDDs you purchase to check for bad sectors before using them (whether WD, Seagate or otherwise.) It takes a bit of time but well worth it. If you find any bad sectors you can do an RMA before entrusting it with your data. For WD drives, you can use DLDIAG (Data Lifeguard Diagnostics) which you can download free from WD’s website.
