• Appearance of the drive also has a role. Beautiful device looks stylish on the table and will attract a lot of curious looks.
• As for speed, there is no need to buy the high speed. A standard 52 speeds enough “eyes” on all occasions. Especially that recording at high speeds is often incorrect. Yes, and the drive motor may quickly fail if abused too often work at high speed.

The manufacturer – here is a clear no recommendations. In principle, all companies today produce good quality external drives. Every company has a good and not too model. But frankly bad today is not found.
