## Questions & Answers

**Q: Is this a smr or cmr disk?**
A: This is a SMR Drive. 
WD##EFRX is CMR (Good for NAS)
WD##EFAX is SMR (Bad for NAS)

**Q: Why are there two of these on Amazon both exactly the same but different prices? The more expensive one has more reviews.**
A: One is SMR (Shingled Magnetic Recording, the other is not. This SMR version is completely unsuitable for NAS - do not buy it for that purpose. Search online to find the various articles about why SMR technology is entirely improper for NAS, even though Western Digital Red is sold as if it was. WD are being sued in the US to attempt to prevent them doing this - unusually this is not for money but just to block WD so that gives an idea how much of an issue this is. If you have already bought this disk for that purpose, return it and any problems, go down the 'unfit for the purpose for which it was sold/advertised'.

**Q: Is this good for nas running cctv?**
A: I use them in my nas although I do not use cctv I cannot see why they would not be ok.

**Q: The title of the listing of this product says 4tb but in the spec description it is listed as 3tb. which is it?**
A: Re: Western Digital RED NAS Hard Drives
I would be guided by the WD Hard Drive version stated. For Western Digital RED NAS Hard drives
it is currently WDxxEFRX, where xx equals the two digit drive size: eg 30 for 3TB, 40 for a 4TB.
However, for a 12TB it is normally WD120EFAX.
Trust this helps. Regards Ron

## Customer Reviews

### ⭐⭐⭐⭐⭐ Really reliable NAS drive
*by M***L on 30 October 2024*

I've bought many of these over the years - all have worked perfectly and still do.

### ⭐⭐⭐⭐⭐ Good slow but durable drives
*by A***N on 19 September 2024*

Inexpensive, durable but slow which is reasonable because faster hard disks tends to die earlier.

### ⭐⭐⭐⭐⭐ Works great for home Nas storage.
*by G***Y on 19 February 2022*

Been using 4 of these for the last 5 months and they have been working great. Only thing to note is use good quality sata cables otherwise they start giving errors. Replaced with good cables and never had another problem. Will be buying these again.
