I guess that this boils down to "always use full-disk encryption".  Just
remember to benchmark your CPU to make sure you're using hardware-accelerated
AES or you're going to lose a lot of performance from this SSD...

TRIM is not meant to be a security feature.  It is optimized for reducing write
amplification and improving performance.  It could have been implemented to be
more secure while trading off on performance.

Quoted from the article:

More SSD drives appear to follow the Deterministic Read After Trim (DRAT)
approach defined in the SATA standard a long time ago.  This in turn means that
a quick format is likely to instantly render deleted evidence inaccessible to
standard read operations, even if the drive is acquired with a forensic write-
blocking imaging hardware immediately after.
