SSD Partitioning and Wear Levelling

Hi

 

I've just installed a 480G Pro drive on an old laptop and partitioned the drive 78/368 for OS & data respectively.

 

Will partitioning the drive reduce the ability of TRIM to implement wear levelling on each partition or is wear levelling done across the drive regardless of partitions?

 

Cheers - Andy

TRIM and wear leveling are two different things that are not really related. Wear leveling is done by the SSD controller and will be done regardless of the partitions.

Hi.

 

OK thanks for that.

 

Having done a bit of reading; will partitioning the drive degrade the ability of the drive to optimize it's life through wear levelling?

Re: SSD Partitioning and Wear Levelling

wear leveling is done at a lower level than the partition table so it should not have any effect on wear leveling.

Yep, drives have no awareness of the file system as far as I know. Else you'd have to actually buy a drive supprting your file system.
