SSD preferences

Last updated on Apr 1, 2023

On the SSD tab of the preferences dialog you can fine tune defragmentation and optimization of solid state drives (SSD) and also correct detected disk types in case some of your disks are incorrectly identified as SSD/HDD.

Unlike old school hard disk drives, solid state drives do not have mechanical parts inside and use memory chips instead to store all the data. Because of that their optimization requires special techniques. Thankfully, you don’t need to worry about that. The latest version of UltraDefrag uses a bunch of smart techniques to squeeze every bit of performance out of SSD and also prolong its lifespan during defragmentation and optimization.

First of all, UltraDefrag skips all files having less then 20 fragments during SSD defragmentation by default. Slightly fragmented files located on SSD do not affect system performance much and their defragmentation would just waste your time and shorten the lifespan of your SSD.

Then, after each defragmentation UltraDefrag executes a special TRIM command which further improves SSD performance and prolongs its lifespan.

And finally, during SSD optimization UltraDefrag performs defragmentation and trimming of the disk only by default, because sorting of files doesn’t give much performance gain in case of SSD and just wastes time and shortens the SSD lifespan.

We do recommend to keep all the default settings intact unless you want some experimentation 🙂
