Hello,

I'm going to setup F20 with a new SSD disk (256gb Samsung 840 PRO) and was wondering about best practices for Over Provisioning during partitioning.

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 guess it's really depending on what SSD you are using. I'm not sure though, that's why I'm asking.

I am doing some more reading on the wiki and found one article (https://fedoraproject.org/wiki/Acer_Aspire_One) that discourages using swap on the SSD becuase of slow write times.  Is that still true?

Also discourages using LVM.  I have often wondered why I use LVM on my notebooks; I don't see the gain over just plain EXT4 partitions.  I have read a number of articles and I can't find any solid advantage.

 

I chose the M500 over the 840 based on price and reviews.  The M500 uses MLC NAND compared to the 840 using TLC NAND.

840 PRO is using MLC NAND
