FileVault 2 Issues and downside?

I've been researching the downside of enabling FileVault 2 (FV2) plus my own experimentation. I am aware of the performance hit and the importance of not forgetting/losing the PW and/or creation key. Also, certain 3rd party SW requires 10.7 & 10.8 to access drives locked with FV2 such as Micromat's TechTool Pro and Protogo. And I've discovered that to mount a FV2 drive as Target Drive, the computer doing the mounting must be running 10.7 or 10.8.

Is there anything else that I'm missing?

TIA.

I just finished turning off Filevault 2. For all who happen upon this thread looking for recent information, here it is.

Corsair FORCE GT 480GB 1.5yrs old. Writes on file vault 2 were under 250mb/s. Noticed the performance degradation.

Secure erased free space

repaired disk

disabled file vault 2

New write speeds are 438mb/s almost matching the read speeds at 4510 mb/s.

FileVault 2 will show you extreme performance degradation and should be avoided for all who spent the money upgrading to an SSD.
