hmmm. I just ordered a Crucial M500 256GB SSD for my new install. I
thought I would have it all to work with (currently using a 320GB HD, so
that is a 64GB reduction already). Are you implying here that you need
to not use all of the SSD drive so that it has some swap around?
I chose the M500 over the 840 based on price and reviews. The M500 uses
MLC NAND compared to the 840 using TLC NAND.
