TRIM support for SSDs used for Dashcam/Sentry?

[Mr.Slow]

Does the current firmware do wear leveling on flash drives and SSDs?

Doubtful. Too many variation (different products) for them to make an effort.

A couple things. The thread title is inaccurate.

TRIM is not wear leveling nor related to it. TRIM is a performance feature. It causes data to be deleted from a "sector" immediately, instead of simply marking a sector as available as traditional HDDs do. This is important for performance because an SSD can't write to a sector that is already populated. It must erase the sector, then write. Does this really matter for Dashcam/Sentry? Probably not. Unless Tesla starts writing much much higher bitrate video to the drive than I've seen so far.

Wear leveling is a different animal altogether. I won't go into details of how it works because there are a lot of techniques, and it can be in hardware, software whatever. But support for it, in whatever form your drive has, is definitely built into the OS Tesla is using or your drive would wear out very very quickly with constant video storage.

Doubtful. Too many variation (different products) for them to make an effort.

This is why we have standards in the hardware/software world.

Thanks for the clarification! Sorry I conflated the two!
