when i first setup my computer about a year ago, i left it at the default AHCI when i installed windows 8. after doing so i was told by a computer tech that i should've just used RAID. i was confused as i am used to thinking of RAID in terms of RAID 0 (striping) or the other method i've used in the past is RAID 5, but never even thought of it for one solid state drive.
he explained that AHCI was a subset of RAID anyhow, but not the other way around, and it had to be done at the very beginning, before installing the OS or anything, so i should keep it in mind for when i do a reformat/refresh.
so here i am, ready to redo my rig, and i'm still not sure why i should be using RAID.
- do i not lose the ability to TRIM with RAID?
- at what point would i 'tell' the computer i want it formatted as RAID? In the BIOS?
i made the mistake of doing a clean install without designating any format, as i don't recall there being a choice. then after it installed, i went into the BIOS and changed it from AHCI to RAID - and it did not like that of course! :) so i switched back to AHCI, and no issues.
so i just want to make sure i do this right, from the beginning.
what should i use for putting windows 8.1 x64 on my SSD: RAID or AHCI?
thank you very much for any assistance.

The reason to use RAID (when you don't have an array) in the first place is in case you want to add other drive later to form a RAID array. If you setup as RAID in the first place, you won't need to reformat to enable RAID later. – Ƭᴇcʜιᴇ007 – 2014-09-03T20:55:25.327
