Is it OK to add larger sized partitions on an SSD?

I read somewhere that it would shorten the life of the SSD and that the Over Provisioning will only benefit the last partition. I have a 250GB Samsung 840 Pro and the OS only needs about a 60GB partition.

Don't bother with the over provisioning.

Just make it all one partition. Over provisioning is the practice of SSD manufacturers putting extra capacity in the drive so that if a block of NAND fails, it can be swapped to a fresh block. Your SSD is listed as a 250GB drive, the actual NAND is 256GB - so you have 6 extra GB of blocks in there.

As for it only benefiting the 'end of the drive' that's completely inaccurate. The drive has a wear leveling algorithm so that the block writes are rotated around so that any single set of blocks isn't preferred over another set. This extracts maximum use from all the blocks.

Just make a single 250GB partition, let the drive controller worry about wear leveling, and don't worry about the spare area.

I like to keep just my OS on a 60GB partition so that it's easier to backup and restore. I then store my data on the additional partition.

Well, that'll work too.
