Since that i can't use TRIM, i wanted to setup in my SSD disks a free space (10%) so that the SSD's controller uses that to do the wear leveling.
How can i do that? With fdisk?
Also, i read this online:
the capacity of these Intel SSDs is about 15-20% higher than advertised, the excess space being used for wear leveling.
If this was true, i shouldn't worry about setting up this little free partition, but i would like to have a confirmation from you.
