WD Red 4TB WD40EFRX NAS Hard Drive

These hard drives are made for 24hr use in a Network Hard Drive systems. Well manufactured to stand the rugged environment of 24/7 abuse. Highly recommended.

Great WD Quality

These two 4 TB WD Red drives went into a Synology 216+II NAS also purchased through Jet. I expect years of trouble free service from WD brand drives. Never had one fail yet. Delivery was amazing from Jet. Standard free shipping arrived in two days. [This review was collected as part of a promotion.]

Excellent Value

I was looking for a 4TB hard drive with good rating on reliability, the search lead to a WD Black. Ordered one from Amazon, but it was a DOA. Returned it, decided to try WD Red from WalMart.com. It was smooth installation and tested out good. Highly recommended.

Great Buy

I'm building a Nas and these were a good bang for the buck.

Best deal in town for this hard drive

Good product and best deal in town

Western Digital drives are the best!

Reliable, good price, and great quality. [This review was collected as part of a promotion.]

WD Red 4TB

I researched this drive as well as others before deciding on this one. My reseasrch started because I had a Seagate 3TB external that failed. While reading about the backup drive I duscovered the model and serial number of my drive had a 32% failure rate. That is not a typo. 32%. Further investigation revealed that the backup drive was only intended to spin when in use. I had mine plugged into a USB 3.0 port and was always on and never thought about it again until it failed. If you have a external drive go to the settings and set a two or three minute spin down when not in use. So my research for a new drive focused on drives and manufacturers that had a good track record and reliablity in server configurations which do spin all the time. I chose the 4TB here based on customers reviews in server use. I decided on the internal because you really dont know what drives are installed in the external setups.

Great Drive

Great drive for a reasonable price if you are using it for home or small business applications.

Not what I expected. Lot better.

I did not expect Walmart to carry this item. Just did a search on the website. Wow! So I ordered two of them. Glad I did my search. No issues. Items were delivery a few days early than expected.

Get the 5TB & 6TB versions with 1.2TB platters...

I've researched quite a bit for about 6 weeks and ended getting a sweet deal on the QNAP TS-453 PRO on Walmart.com. Thought I was getting a sweeter deal ($1,490) for a 20-pack, but it was too good to be true...It must have been a misprint. I just received one 4TB Red NAS for $149. Anyway, I returned the 4TB version and ended up getting 2 6TB version for RAID 1. Same NAS 3.0 firmware, but the denser platters (1.2TB) seemed to perform better thus far in terms of transfer rates etc...Really quiet and cool.
