As i can see Antergos uses continous TRIM by default, or does CNCHI any check and choose depending on the SSD information?
Reading here: https://wiki.archlinux.org/index.php/Solid_State_Drives#TRIM
Warning: Unfortunately, there are wide quality gaps of SSD’s bios’ to perform continuous TRIM, which is also why using the discard mount flag is recommended against generally by ext filesystem developer Theodore Ts’o. If in doubt about your hardware, apply #Periodic TRIM instead.
Note: Before SATA 3.1 all TRIM commands were synchronous, so continuous trimming would produce frequent system freezes. In this case, applying #Periodic TRIM less often is better alternative. Similar issue holds also for a number of devices, for which queued TRIM command execution was blacklisted due to serious data corruption. See Wikipedia:Trim (computing)#Shortcomings for details.
So may on some SSD Devices it would be better to use Periodic TRIM
Theodore Ts’o say: …For these two reasons, on Linux the recommended way to use TRIM is to use the fstrim command run out of cron, so that during an idle period the TRIM commands can be issued for all of the unused areas on the disk.
After reading all this it is a bit confusing what should be the one option to use…
But may it would be better to have a checkup what to use???
Because that C-TRIM can caus system freeze is reminding me on a lot of Posts on system freeze here in the Forum, i do not check may there are mostly with SSD Systems??
Me i get system freezes before with no real log to reproduce what it is caused by… After changing to P-TRIM i get not one FREEZE again like this (system freezes unexpected, only cursor is working)
