- Key Specs
- Storage Capacity: 4000 gigabytes (Measured in megabytes (MB), gigabytes (GB) and terabytes (TB), this is the amount available for storing files, music, movies, photos and more. The total includes the capacity of the hard disk drive and solid state drive if both are included on the computer.)
- Storage Drive Type: HDD (Traditional, mechanical hard disk drives are the most common type of storage because they're relatively inexpensive and offer huge capacities. However, they also generate both noise and heat. Solid state drives, also known as SSDs, are many times faster than hard disk drives and have no moving parts to wear out, but typically offer less capacity for the same price.)
- Rotational Speed: 5400 revolutions per minute (The rate at which the hard drive spins its platters. The higher the rotational speed, the faster the drive can read and write data.)
- Maximum Read Speed: 175 megabytes per second (The greatest speed at which the device can read information; for example, opening files.)
- Maximum Write Speed: 175 megabytes per second (The greatest speed at which the device can write information; for example, saving files.)

Western Digital... ALWAYS!
You see this? You want this. You know why? It's a Western Digital, start there. It's a Red Plus = Fast, reliable, NAS. It's the right price. AND It's the actual best model offered... It's the WD40EFPX model, meaning... - It's a CMR drive (not the cheaper, less reliable and slower SMR drive). - It has a 256mb buffer (not 128mb) - It's a PLUS series... Faster than Red, slower than Pro, still super fast for an HDD. - It's built to last... for servers, RAID and home use. Oh, and it's almost the same price as a Blue (entry level). Bottom line, for backup and daily access... GET THIS!!!

WD Equipment & Support are very dependable
I recently purchased 4 of these to replace the old drives in my 7 yr. old EX4100 NAS configured to RAID 5. I hope the new ones hold up just as well. Had issues backing up loads of data and then uploading. I believe the bugs were not in the drives but issues with the other devices and wifi. WD support was excellent and attentive. Take pics of the serial numbers before installing.

Reliable NAS drive for home server
I bought the WD Red Plus 4TB for my home NAS running TrueNAS, and it’s been rock solid so far. The drive runs quietly, stays cool, and has been working 24/7 without any issues. I’m using it in a RAID setup, and the performance is great — good read/write speeds and all SMART values are healthy. If you’re building a home server or upgrading storage, this is a solid choice. I’m already planning to grab another one to expand my array
