Erase

Erase feature is designed to remove all user data from a drive permanently. This command will put the drive back to its original out-of-box state. This will initially restore its performance to the highest possible level and the best (lowest number) possible write amplification.

The below given CLI input will perform the erase operation on the selected disk:

magician --disk -1 --erase or

magician -d 1 -E

Note: When the disk is in frozen state, the user has to unplug and plug-in the power cable and restart the erase operation.

Write amplification is an issue that occurs in SSDs that can decrease the lifespan of the SSD and impact performance. The lower the write amplification, the longer will be the lifespan of SSD.
