Key Specs
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.)
Interface(s): SATA (Refers to the types of connections that devices use to interact and communicate with each other.)

Bought Two
Researched replacing my two terabyte drives. Thought about sticking with Western Digital but for the price and performance these drives were a better deal. Cheaper, better performance and excellent warranty. I bought two drives both are performing very well.
