I use full drive encryption (FDE) w/ TrueCrypt on my laptop. I have a 2nd gen I7 with AES instruction support, so honestly I can't even notice a speed change on the system with it on.

My question, is for those who know about SSD's a lot. I previously (early 2011) read articles about how software encryption will negate the speed benefits that an SSD provides - because of the need for the SSD to send a delete command, then a write command, for every encrypted write - instead of just writing over data like a regular HDD would (or something like this...honestly I can't remember...ha!).

Anyway, any improvements in this field? Is it pointless for me to grab an SSD if I'm using FDE?

Thanks all.
