Are Self Encrypting Drives Useful For Data Security?


Hello Alden.

I'd like to outline the advantages of self-encrypting drives first:

1.  There is negligible performance hit as compared to software-based encryption due to the encryption being at the firmware level.

2.  Users can sometimes tamper with software-based encryption by turning it off without notifying their network administrators.  With self-encrypting drives, this will not be possible.

On the other hand, here are the disadvantages:

1.  It is costly because enterprises will have to replace their current hard drives.

2.  There is currently no way to centralize management of these self-encrypting drives.

To answer your question, yes, it can be said that self-encrypting drives are more secure than conventionally-encrypted hard drives.  However, the cost of ownership hinders its adoption.

Hope this provides you with some useful insight.
