    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.

    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.

    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.

    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.
