Desktop Drives vs. WD Red Plus

Do right by your NAS and choose the drive pur-pose-built for NAS with an array of features to help preserve your data and maintain optimum per-formance. Take the following into consideration when choosing a hard drive for your NAS:

• Compatibility: Unlike desktop drives, these drives are specifically tested for compatibility with NAS systems for optimum performance.

• Reliability: The always-on environment of a NAS or RAID is a hot one, and desktop drives aren’t typically designed and tested under those conditions like WD RedTM Plus drives are.

• Error Recovery Controls: WD Red Plus NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system.

• Noise and Vibration Protection: Designed to operate solo, desktop drives typically offer little or no protection from the noise and vibration present in a multi-drive system. WD Red Plus drives are designed to thrive in multi-bay NAS system environments.

Rating Breakdown












  • WD Red Plus Drives are very dependably.
    Verified BuyerReviewed by Anonymous reviewer - 13 novembre 2021

    I installed 2 of these WD RED Plus 10TB drives in my WD My Cloud Ex2 Ultra and set them to Mirror RAID. I reloaded 6 TB of data which took 7 days and the drives worked flawlessly. These drives are quiet, fast and well worth the money. If you have a lot of data to store, I highly recommend these drives for you. My old WD Red 6TB drives worked for 6 years, until I ran out of space, with no problems so, I trust the WD Red drives to hold my data and so should you.

  • Really fast and incredibly quiet.
    Reviewed by Xulonn - 30 juin 2021

    My 10TB WD Red in a new single bay light blue NAS replaced a 4Tb HDD in a different 3-y/o single bay NAS. With no other changes or tweaks to my system, my Intel NUC Corei7-8955U transfers large files to the NAS at around 40MB/s compared to 9-10MB/s for my old NAS. Plus, the WD Red is so quiet that I can barely hear it compared with the loud clunking noises of my old NAS HDD.

  • Quiet, works with Synology DS1812+ *
    Reviewed by Synology Owner - 9 octobre 2021

    Arrived on time, packaged well. I was searching for replacement NAS drives to replace the failing ones in my Synology DS1812+, which can occupy 8 drives. Synology's Qualified Vendor List (QVL) lists Enterprise drive models that are impossible to find in new condition. After reading about Western Digital's collaboration with NAS-makers and the fact that this 10TB drive works in many 8-bay storage systems, i rolled the dice and won. Backing up multiple Terabytes of data is no picnic! Once I got it done and rebuilt my RAID arrays using these drives, the first thing that struck me was how quiet they are. My older 4TB drives roared and hummed. * * * NOTE : FOR OWNERS OF SYNOLOGY DS1812+ * * * I had to make one minor modification to the drive trays to allow these drives to sit flush with the bottom: Cut off one of the plastic nibs, which usually aligns with the threaded holes on the bottom of the drive. The drives work swimmingly well. I've successfully installed DSM, created RAD5 and restored 12 TB of data.

  • Works great for my NAS
    Verified BuyerReviewed by Anonymous reviewer - 12 novembre 2021

    I have nothing but praise for this hard drive. This is my second one just with higher capacity. I use it to stream my movies, music, tv shows through plex and never had any issues. Love it. Thanks

  • Great for Unraid Server
    Verified BuyerReviewed by Anonymous reviewer - 10 novembre 2021

    Excellent drive. Have 2 10TB drives in an Unraid server (so 10TB usable). Since my server didn't have much cooling, I added a fan to the hard drive to keep it around 40C.
