I have several, work well in Synology NAS
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.My Synology DS1511+ now has 2 of these and 3 5TB drives (could not get the 5TB any more). They have performed well so far, reliable and fast enough for the 5 bay NAS for my uses. These are WD40EFRX drives in the box.

HDD fail after 31 days of operation.
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The sale experience was great and the staff were highly responsive. The HHD was not stocked in store so i ordered it online. Tries to register the two drives with WD.com but was told the manufacture ----- We apologize for the inconvenience but based on the serial number you provided, our records indicate the Build Date of your drive was [10-APR-2017] -- 31 days in the drive fails! Now i have to battle with WD for an RMA. Always check the date on these HDs when you buy.

WD Red drives have proven reliable
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I purchased two of these 4TB Red drives on a daily deal to replace the remaining 2 2TB Seagates I had on my Synology NAS. 1 of those two Seagates had a SMART failure predicted error and some bad sectors after around 5 years (so not bad for a non-NAS specific drive). I have 3x 5TB WD Red drives also in the NAS, but WD stopped selling the 5TB units and the 6TBs are too expensive. I am happy with adding these 2x 4TB in the NAS and am using Synology Hybrid Raid (SHR) so can do mixed sizes. The 5TBs have been rock solid so far so I am expecting these to be good too. As you can see from the attached picture, the 4TB drives give you 3.6TB usable, and the 5TB ones are 4.5TB.

So far so good.
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I purchased 2 of these for my WDPR2100. Both arrived within a few days and after a lot of trial and error, I finally was able to upgrade my NAS to 8TB (4TB Raid 1). I wish BB had a larger selection of higher capacity NAS drives and had them available in the stores. I see all the videos about the shucking EasyStore Drives, but I didn't really want to tear open drives and hope they were correct. Happy so far and loving the larger capacity.

THE NAS go to drive.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The WD RED series NAS drives are close to bulletproof; though, that is not a literal statement; so, please don't test the validity. Run these drives in a 4bay Synology DT Server, and they are awesome. Not super fast, but not slow either. Use four others as safe-stored backups...just in case. Used them for years, gazillions of read/writes over a dozen users...never had one fail. I don't have anything to compare them to because I haven't had a reason to try anything else. These do the job well.

Good inexpensive drive
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I am using this drive with WD Acronis TrueImage Backup software in an external dock connected to my desktop with USB 3.0 containing slots for 2 SATA drives. The highest speed as per the Acronis software was 884MBps. The other drive in the same dock I used is 2TB SATA SSD.

Gets the job done, BUT this is the SMR Model
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.If you know anything about hard drives today. Manufactures came out with a 'newer' technology called SMR vs. the older tech CMR. You would assume the 'newer' tech is better; but that is kind of wrong and is misleading. SMR was developed to create more space on less platers. but sacrifices performance. CMR drives currently will perform better (faster) then SMR drives. SMR drives also have issues with file systems such as ZFS. Also, SMR drives have can take a lot longer (like 3x, 4x, +) to rebuild a failed drive in an raid array or unraid array. Keep in mind longer the rebuilding process takes, more likely another drive could fail. Simply put, if any of this is a concern to you, stick with CMR drives.

Hopefully Reliable for my Desktop Second Drive
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I never have enough space. I backup like crazy, sometimes I have so many duplicates I get confused as to what is master and what is a backup. I hope this helps. I chose the 4TB WD Red (NAS) for reliability. 5400 RPM almost stopped me from the purchase but all is PLENTY fast. I think this would be a SUPER 2nd drive for those of you going the SSD route. I'm waiting on a sale to pick up another. Remember, I backup everything.

Q: QuestionWhat's the difference between this drive and the WD40EFRX?
Asked by Anonymous.
- A:Answer None, that is what this drive is inside the packaging. This is the retail kit. See my attached screenshot from my NAS showing the two I just picked up recently.

Q: QuestionWill these red drives work in computers themselves or is there something in programming or something that'd make them incompatible? An extra 20.00 for 24/7 build thought doesn't sound too bad to me compared to the green, black is more expensive than these
Asked by Eugene.
- A:Answer In simple terms, these can be used in regular PCs, but you are paying for features that you will not use or not very helpful for regular PC user. In fact, one could argue that one of the features supported by these drives is actually (mildly) harmful to ordinary user. Now the long explanation. RED drives are meant to be used with RAID controllers. RAID controllers manage error recovery differently and therefore need disks to limit the time they spend recovering data from platters. Thus there drives will not try as hard as they could try to recover data when something goes wrong. This feature is called TLER (time limited error recovery) NAS drives have TLER supported and usually turned on by default. It may be possible to turn it off. However why would you pay for this and other features (like vibration tolerance/sensors etc) and not use them? Note that desktop drives usually do not have TLER and you should not put them in a RAID enclosure.

Q: QuestionIs this SMR or CMR Drive? P.S. BestBuy should include this in every HDD product discription.
Asked by VoidDilation.
- A:Answer A little bit of researching shows it's SMR (shingled magnetic recording), as are all WD RED. WD Red Plus & WD Red Pro are CMR (conventional magnetic recording) source - https://blog.westerndigital.com/wd-red-nas-drives/

Answered by MacChiyuan
Q: QuestionWill this drive work in Apple Macintosh G3 running Mac OS X 10.4.11?
Asked by mdsmithx69.
- A:Answer WD Red drives are optimized for NAS usage. You should probably go with a blue series or black if you want higher performance. Those are optimized for desktop use.
