El Capitan and TRIM Support

[Tucom]

I've enabled TRIM via TrimForce officially from Apple on my install of Yosemite, and if I were to update to El Cap via the App Store (not a fresh install, but an upgrade) will my trimforce being enabled in Yosemite carry over to El Cap immediately, or will I have to go in and disable rootless temporarily and re-enable TRIM again?

It should, it did for me but remember El Capitan isn't fully cooked so anything COULD happen.

True, thanks for the reply. I'm sure there'll be a good bit of info about this when it goes gold.

It carried over for me also. I did not need to reenable Trim.

I found that on El Cap public beta 2 that one does not need to disable rootless to use the TrimForce command. Just run trimforce enable in terminal; the computer will reboot and TRIM will be active.

Awesome. What happens if you try to do this on older betas of El Cap? Like will it throw up an error via Rootless disallowing it to happen without disabling Rootless first?

Public Beta 1 was the same. Don't know about the Developer Previews.

It was easier than I thought...
It is:
fsck_hfs -fy /dev/disk# (# of your disk, no -l option)

Would this work for / need to be modified for: 2 internal SSDs in a RAID0 array used as boot volume? Thanks in advance!

I think so, as my External SSD is also 2 x 512 GB SSD in RAID 0. (LaCie Thunderbolt enclosure).
