The ‘SSD & Flash Wear Leveling Warning’ that you link to is a *security* concern, not a performance or functional concern. The concern is that unencrypted (plaintext) data could be stored on a block not accessible to the Operating System – one reserved instead by the device’s wear leveling mechanism. I am simply clarifying for readers who may misunderstand.

…just take all of the space available and encrypt it with truecrypt. all i’ve read about that indicates, that it doesn’t matter at all if you decide to use all the space available…

Ok. I think I understand what you saying. I have a brand new Crucial M4 128GB SSD, never been used, I have it plugged in right now but not done anything with it. So given my scenario, what would you suggest?

Many Thanks.

with new drives like intel’s 320 / 510 series, ocz’s vertex 3 etc. this isn’t a problem anymore as manufacturers have increased spare areas to 10-15% of a drive’s capacity. if you stick with some older ones go for sth like 5-10% of drive’s capacity.

important: you first have to secure erase your SSD, then partition with that additional spare area to make it work. if you simply shrink existing partitions or delete existing ones, the controller won’t use the space as spare area…

You say you should leave some unpartitioned space for the controller to use for wear leveling, how much for an 128GB SSD, say 1GB unpartitioned space?

So this whole article can be condensed to “don’t use security products unless you need security”? Okay…

Michal, this post is titled “performance and durability”, not security BTW: security would be a very interesting topic to cover, unfortunately I’m not competent in this area.
