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.
thanks, this helps... I guess I probably have more questions than I started with now. haha. So, what hard drive is the ideal SSD for using FDE w/ True Crypt? Would love some precise models.. I don't mind software encryption (vs. hardware) - because the I7 handles it fine. Beyond that, it sounds like I'm looking for one that does NOT use wear leveling - but what is the life I can expect out of this - half of normal?? – Shackrock – 2011-11-16T18:09:41.993
We don't like to give specific shopping recommendations on Super User, but any non-SandForce drive should be fine. Even if you could find an SSD that didn't use wear-levelling, this would be a very bad idea. Not only will blocks start to fail relatively quickly, but the drive's performance will drop off. – sblair – 2011-11-17T13:34:07.777
ok. So, any non-SandForce drive that DOES use wear-leveling is a keeper? – Shackrock – 2011-11-17T14:42:19.860
Yes. There are other things to consider, such as overall performance, warranty length, and cost (obviously). So, as always, it's best to check a review or two before buying. – sblair – 2011-11-17T15:01:33.653
