Frequently Asked Questions (FAQs)
1. What is a SATA external hard drive?
Introduced in 2003, SATA (or Serial Advanced Technology Attachment) is the default interface for most desktop and laptop hard drives. They are referred to as SATA hard drives, but they are actually rotary hard drives with spinning platters and a moving needle that writes data to consecutive sectors on each platter.
2. Can we use SATA hard drive as external?
Can an internal drive be used externally? Yes. Hard drive caddies - or enclosures - are effectively SATA-to-USB converters and allow you to turn an internal SATA hard drive into an external one that you can use for storing or backing up files, or to keep a library of videos that you could leave attached to your TV.
