- Key Specs
- Storage Capacity: 20000 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: 268 megabytes per second (The greatest speed at which the device can read information; for example, opening files.)
- Maximum Write Speed: 268 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.)

- Memory
- Cache Buffer Size: 512 megabytes (The data capacity of the cache buffer (or disk buffer) that acts as temporary memory for the drive. The cache holds the most recently and frequently used data to save the drive the extra step of pulling it from permanent storage every time it's needed, which helps increase the drive's overall speed.)

Great for Synology NAS
It's been a few months running 4 of these HDDs in my Synology 923+ and so far no issues. Health checks come back perfect and haven't had any issues.

Unreliable?
Whenever I buy HDs, I always run a "check for bad blocks" long test. I bought four of these during the Black Friday sale to use in a TerraMaster F4-212 NAS. Each one aborted an extended (long) S.M.A.R.T. test ran through the NAS GUI, ssh, and even Western Digital's Dashboard software (used with an Insignia hard drive dock). Now, upon trying to re-test the boot drive, it fails to start up and is caught in an endless loop of the read grind. How can four brand new drives be defective?
