Key Specs
- Storage Capacity: 1000 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.)
- Interface(s): SATA (Refers to the types of connections that devices use to interact and communicate with each other.)
