- Key Specs
- Storage Capacity: 18000 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: 7200 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: 272 megabytes per second (The greatest speed at which the device can read information; for example, opening files.)
- Maximum Write Speed: 272 megabytes per second (The greatest speed at which the device can write information; for example, saving files.)
- Form Factor: 3.5 in.
- Interface(s): SATA (Refers to the types of connections that devices use to interact and communicate with each other.)

Works great, smidge noisy
Hard drive works great. It has been running 24 hours straight since I purchased. Subtle noise, but annoying but otherwise fine.

Good drive
A little slow to spin up. A little noisy at first. Other than that, I have no other issues. Speed is good. Works great with my NAS. Tons of space. I’ve always trusted WD drives.

Excellent NAS Drive - Waited for price drop
I have been using WD drives for over 15 years with no issues. Therefore, I was not surprised to find that this 18 TB drive is an excellent drive. However, the first drive I received was defective and could not be formatted, which caused Windows Explorer to freeze. The second drive I received was without fault and now have it running in my home NAS.
