It runs great and performs great as a second hard drive but lacks performance when used as the primary windows drive

Best value. It spin downs and sleeps too much but it's cheap and reliable. Not recommended for system drive. Best for backup and slow speed access like movies, photos, music etc.

Despite its speed of 5400 RPM, this drive performs quite well for a spinner, and stays relatively quiet. No issues here.
