Customer Ratings & Reviews

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.

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.

Installation was a breeze. Large enough to free up space so C drive had only OS and room to run much faster. Also large enough to remove 2 other storage drives for less drain on power supply. Worth the money.

I have seven of the WD Red 4TB drives and only had to exchange one as it was DOA. Drives work great in NAS enclosures or stand alone in a desktop. Highly recommended drive.

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.

I've paid full price for this but no regrets.. If I waited longer time I would have used easy store 8 TB.. but as I mentioned I've no regrets and going strong in my NAS

Needed more room on my main computer. Excellent price for 4Tb of storage. Wont' need the fast gaming speed as this drive is mainly for photos. Just plugged into the Sata and power, found the drive on systems manager and one click it was up and running. I do have an SSD drive for the OS, so this NAS drive is just for storage. I'm hoping that it should be plenty reliable.

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.

I really have no complaints with this drive great size runs just fine I've never really had any issues with Western Digital drives

I bought this is an exact replacement for a WD NAS I have after one of the mirrored drives failed after 3 years of constant usage. It's slow and fairly expensive by today's standards but is quiet, power efficient (only gets warm under heavy load), is reliable, and a quick and easy plug-n-play solution for NAS storage given its NAS firmware support.

Used it to build myself a Plex NAS and this had a great price on it. The NAS drive is meant to be running 24 x 7 with higher utilization. Recommend.

So far working well with my NAS drive for backing up photos. Crossing fingers and eyes....

I bought this to replace in a Synology NAS. My old drive was several years old, but still a WD. I'm not sure why the old one failed but this was easy to set up and works flawlessly so far. Can't complain.

Plugged it in to my server and has been working 24/7. Easy setup and install.

Solid drive, great price for the performance and size. Using it in an external enclosure for backups and general data storage. No issues and a good warranty.

Hard drives run at about 80 to 90 degrees in my NAS unit after 24 of read/ writes Nas hard drives are built better to withstand 24/7 operations Nice and quite

I have 2 Synology boxes, both run WD Red drives (4x3TB and 2x4TB systems). Very reliable so far (some are over 2 years old), and they perform extremely well.....all for a reasonable price. Very happy!

Solid harddrive for my Synology NAS with good performance at a reasonable price when on sale. No problems or errors after 8 months.

Four terabytes at a one hundred and fifty dollars was worth it, bought two for use in as a mirrored see, RAID 1. Quieter than expected.

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.
