    • Consistent speed (CMR), quiet 5400rpm, TOP rated lifespan
Capacity: 8TB Style: Red Plus
My go-to for quiet, dependable, consistent speed storage. The 5400RPM is great for setups where you don't want to hear loud drives all the time. I also like the fact that it is a CMR drive, so speeds are consistent when writing large amounts of data. I needed a drive where I could offload finished video projects long term. Even though I have a separate drive for Time Machine backups, which backs up my Mac AND this drive, this WD Red Plus has my full confidence. Top-rated for long-lasting and dependable storage. I wouldn't use anything else. ... show more

    • Perfect NAS Replacement - RAID Rebuild Success
Capacity: 10TB Style: Red Plus
I picked up this 10TB WD Red Plus as a replacement for a failing drive in my NAS, and it performed exactly as hoped. The unit successfully rebuilt the RAID array using this drive - yes, it took quite a while since I'm running consumer-grade equipment, but that's expected with a 10TB rebuild. The 7200 RPM speed and CMR technology really shine in NAS applications compared to SMR drives that can struggle during rebuilds. Everything is running smoothly now and my data feels much better protected. The 256MB cache and SATA 6 Gb/s interface keep up well with my network demands. WD Red Plus drives are specifically designed for NAS environments, and it shows - no compatibility issues, proper vibration handling, and built to run 24/7. Worth every penny for the peace of mind, especially when replacing a failing drive. If you're running a home NAS, don't cheap out on drives - this is exactly what you want protecting your data. ... show more

    • Solid, Reliable Upgrade for My Aging NAS Drives
Capacity: 10TB Style: Red Plus
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. ... show more

    • As advertised. Deployed into Synology DS920+ with minor (artificial) kink
Capacity: 16TB Style: Red Pro
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. ... show more
