Western Digital 4TB WD Red Plus NAS Internal Hard Drive HDD - 5400 RPM, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5" -WD40EFPX

Why did you pick this product vs others?:After years of faithful service, my original NAS drives were starting to get long in the tooth. Between signs of wear and ever-growing storage needs, I knew it was time for an upgrade—and the WD Red Plus 10TB hit the sweet spot.I’ve used WD Reds in my NAS for years and they’ve always been rock solid. This drive is no exception—quiet, fast for a spinning disk, and stays cool even under constant access. I appreciate that it uses CMR (not SMR), which is essential for proper RAID performance and long-term reliability.Installation was plug-and-play in my QNAP, and it was recognized instantly. It’s also noticeably quicker than my older 5400 RPM drives thanks to the 7200 RPM speed and 256MB cache.If your NAS drives are starting to show their age—or you just need more space—this is a great way to breathe new life into your system. WD Red Plus continues to deliver the kind of reliability I trust with all my critical data.

Works well and quick in my ugreen dxp2800 Nas. Easy to use and install, and the price per TB isn't too bad. 4tb is a good starting capacity for a server/Nas. I do like that it specifically shows that it is for a nas on the front, unlike some brands, and it looks nice.

I recently added the Western Digital 14TB WD Red Pro NAS Internal Hard Drive to my home NAS system, and it has proven to be a stellar addition to my storage setup.

The user-friendly nature of the WD Red Pro series makes it accessible for those looking to establish emergency backups for crucial family information or simply expand their storage capabilities.Having opted for a total of 4 drives for my NAS, the storage capacity has proven more than sufficient for my data needs.

It's a trusted brand that excels in the field of storage solutions.In conclusion, the Western Digital 14TB WD Red Pro NAS Internal Hard Drive is an excellent choice for anyone seeking a high-capacity, reliable storage solution.

These took under a minute each to install into my Synology DS920+ NAS. Since it was all new gear, I let it do a through drive check as part of initializing which took a long time. I think it may ave been about two days. In theory, I could have used it during this time, but I just started it and ignored it.During installation, the 920 whines about any accessories (memory, drives) that aren't Synology's own and that included these. On the 922, they change from whining to much more obnoxious contrived incompatibilities, but this combination was chosen because exactly once, during insteallation, it warns you that its not a supported combination and that's that. Probably if there were a support issue involving data loss, they'd remind you of that oath you took to not complain, but in reality this is a very common combination that works quite well.Fan and normal noise is quite minimal. There was a noticeable clunk during a head seek. I reduced this by offlining the unit so I could remove power then applying the fuzzy half of a hook-and-loop fastener to the bottom of the bottom rail. That gave it support and a little bit of padding so the metal cage didn't serve as a drum skin for the oh-so-tiny motion that got amplified when transferred to the sheet metal.I'm looking forward to getting many, many years from these drives, like I did from the 4TB WD these are replacing. Those drives have no reading errors. Size grows and no drives are infallible, so I opted to replace them on my schedule (OK, and on Amazon Day special. :-) ) instead of letting the drive pick its own replacement day, taking my data with it.
