that was the question really.. should it work with RAID.
please read the question carefully - it says - the controller is in RAID mode. and this is because I have RAID1 connected to it. The SSD is single drive not RAID but it connected to the controller which is RAID mode....
should I expect TRIM to work in this configuration or not?
I did read the question carefully.
What I was unsure of was whether your SSD and Hard Drives were on SEPARATE controllers. In other words, could the Hard Drives be setup as RAID and your SSD be setup on a separate controller as AHCI?
My Asus Z77 Sabertooth has the main controller setup as RAID because I have a 3xSSD setup (older SSD's). There are SIX SATA connections here. My Samsung 840 PRO also falls under this "RAID" setting for the Intel controller even though the SSD isn't setup as RAID. This design is intentional by INTEL for maximum flexibility.
However, my Samsung Magician software complains that my SSD isn't setup in AHCI mode (I can't do that and have a RAID setup on the same Intel Controller).
Windows does report my Samsung 840 PRO is using TRIM, and my benchmarks are proper so everything's fine, just a little confusion due to the Intel requirement to have the RAID heading.
*My Intel Controller supports AHCI and RAID (probably IDE as well) but I have to choose AHCI or RAID. I have SIX SATA connections under this:
#1 - SSD#1 3xRAID0
#2 - SSD#2 3xRAID0
#3 - SSD#3 3xRAID0
#4 - 2TB HDD
#5 - 3TB HDD
#6 - Samsung 840 PRO SSD
So as per the ABOVE, in the BIOS I have RAID selected for the entire group. The Samsung Magician software then does not see the SSD as AHCI despite everything working properly.
*Again, if Windows reports TRIM then it is.
