Software full-disk encryption absolutely kills performance. I wonder if this hardware solution is any faster? Has Seagate released any '5400 vs 5400 w/encryption' speed tests?
It's really not that bad. We use PGP at work, and I would say that it only cuts 'performance' by about 10%. We are using old laptops too, so any newer computers should be hardly noticeable.
The initial encrypt takes ages though--but you can use the computer while it is encrypting. So, it's not so bad.
We have a couple of the hardware encrypted drives at work for testing. We have seen no overhead on the drives. They encrypt constantly. Even during an initial OS install. The only thing the software does for the drive is allow you to configure the authentication. They appear to be a good alternative to software whole disk encryption for any users who have issues with the overhead of software based encryption. We only have two drives, so I'm not sure how painful management will be long term.
