General Information and Ratings 

This chapter contains information about the AF-70 E3 including how to identify the drive 

2.1.

 

Identifying the Drive by Model Number 

Each drive can be identified by its model number, as shown in the table below. The model number is on the shipping label and the drive 

nameplate. The model number includes the drive and any options.
