The WD Red 4TB carries a heavy workload and is on sale for just $90 at Newegg

The WD Red 4TB internal hard drive is down to $89.99 at Newegg with code EMCDGFN29. The code is temporary, but I'm not sure how long it will last. Save while you can. The drive is $117 without the code, and it goes for a lot more than that at other retailers. It's $129 at B&H and $150 at Best Buy. We have shared deals on the 4TB drive before, but it has never gone lower than $90, which makes today's deal a match for its lowest ever. This deal makes the 4TB drive $15 cheaper than the 3TB version, so you're getting a whole extra terabyte and paying less.

The drive is designed for network-attached storage devices, so it can support up to 180 TB a year in data transfer. Can work 24/7 in an NAS environment. Includes firmware to ensure compatibility. Has a three-year warranty.

The WD Red hard drives are specifically designed for network-attached storage devices, which means they are great for building your own media server. Luckily, Black Friday is also a good time for NAS deals. Grab the Synology DS218+ DiskStation while it's on sale for $254.99 from a street price around $300. This is a two-bay system so you'll want two of the WD Red drives to fill it.

Thanks to the huge 4TB capacity, you'll be able to create your own media server with all the music, movies, and other data you could possibly want. Paired with one or two more in a network-attached storage device, you can create a system where each drive backs up the other so your media is never lost. Because NAS devices are designed to serve as backups, you'll probably want to get more than one drive, and that's why deals are the preferred way to buy them.

They've been tested to perform reliably in a 24/7 always-running environment like you would have with a NAS. They also have a heavy workload rate and can handle up to 180 TB a year. WD backs these hard drives with a three-year warranty.
