Internal SSD and SMART status I just ran Etrecheck on my iMac. I got a status report on my internal 250 GB solid state drive. The report stated the drive has SMART capability but that it was disabled.  Is this an issue I should be concerned with?  Does it affect the speed or other functionality of this drive. Most of my software is located on this drive.
Is [SMART being disabled] an issue I should be concerned with? Does it affect the speed or other functionality of this drive.

SMART is a monitoring and reporting tool.
From Wikipedia:

S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology; often
written as SMART) is a monitoring system included in computer hard
disk drives (HDDs) and solid-state drives (SSDs) that detects and
reports on various indicators of drive reliability, with the intent of
enabling the anticipation of hardware failures.

It has no effect whatsoever on the performance of your SSD.
