#Is the solid state drive for macbook pro faster full

A nearly full solid-state drive will have much slower write operations, slowing down your computer. The reason why lies in the way SSDs and NAND Flash storage work.įilling the drive to capacity is one of the things you should never do with a solid-state drive. Fill your solid-state drive to near-capacity and its write performance will decrease dramatically. The benchmarks are clear: Solid-state drives slow down as you fill them up. More importantly, all the above combines to something like a perfect storm on all SSDs, as they fill up: Why Solid-State Drives Slow Down As You Fill Them Up This should not be that much noticeable, though. Then all currently sold SSDs age and get indeed slower over time. On an original Apple SSD trim should be enabled.

Without trim it gets harder and harder to know which cells to use next as the wear leveling is designed to use each cell ideally equally compared to the others. Next it depends on whether you have trim enabled or not. Why is it important to keep lots of freespace on OSX? What is the impact? and How much hard drive space to leave free? To name just one reason connected to the filesystem.

If the free space falls below 25% things start to get complicated and the directory structure gets more and more inefficient.

If the filesystem is HFSplus, then the free space usually needs to be above a certain percentage to ensure smooth operation. The first reason connected to that is inherent to the filesystem macOS uses. While this is certainly not the only reason you may experiencing a slow down, a filled up SSD is one possible reason for slow downs.
