I'm so sick of this TRIM. Constant configurations needed because of it, constant care like "this thing you better don't do on SSDs". And then problems like this.
Do you think there'll ever be SSDs that don't need it?
I remember started incorporating SSDs into their computers and didn't support TRIM. Windows users were telling Mac users their Macs were practically obsolete because it couldn't do this one thing that was enabled for Windows. of course they sent that back to Apple and Apple replied, for years, you don't need it.
Eventually, they relented and enabled it on their SSDs. I'm pretty sure the marketing and engineering butted heads over this one stupid bullet point.
Except without TRIM you'll fill all your blocks and kill performance of your fancy $1500 Apple when the SSD is performing a dozen operations to create a space to perform writes instead of one operation on a properly TRIM'd drive.
Apple didn't do this because of "windows users whining" but because they knew they didn't want an angry mob of customers wondering why their drive is 10x slower than it was on day one.
Arguably, idle GC was "good enough," for some use cases but probably not for drives that aren't sitting idle all the time and on many hours a day. Even then, Apple probably didn't want to tell its customers "let it sit out overnight" to regain performance when supporting plain-jane TRIM was a trivial addition.
On-board GC + OS-driven TRIM are considered the optimal solution for SSD's.
