So, let's say you don't have TRIM available on your external 500.GB USB3 connected SSD. Let's also say your 500.GB SSD is filled up, but it has 10.GB of over-provisioning. You then delete a 30.GB ...

If TRIM is implemented correctly it makes all data unrecoverable (!), but therefore you need to tell the internal controller that every bit on the whole SSD (!) is not needed anymore.

A feature activated by default in Windows 11 Pro causes a significant reduction in SSD performance. Here's how to fix it.
