Your options now depend on whether or not Apple¡¯s implementation of TRIM works on your SSD, and, if so, if TRIM is enabled.
You can find out from the manufacturer of your SSD if your model supports Apple¡¯s implementation of TRIM. ?
You can find out if TRIM is enabled by:
Apple menu ¡ª> About This Mac ¡ª> System Report ¡ª> Hardware ¡ª> NVM Express or SATA/SATA Express ¡ª> scroll down until you find TRIM Support ?If it says ¡°Yes" then TRIM is enabled.
Thanks for that nice summary. I¡¯m hoping you can comment a bit more. My SuperDuper Clone resides on the Thunderbolt controller enabled 1 TB SSD stick from OWC. Here¡¯s what System Report says about IT:

My questions relate to two items in that table, the first being?
what is meant by ¡°Detachable Drive¡±? (Would that related to a multi-disk caddy rather than something that can be plugged in and removed from one of the computer¡¯s Thunderbolt port(s)
And the second:
the same question as it relates to ¡°Removable Media.¡±
Thanks so much,
