To clarify, I'm talking about using the firmware RAID, built into the motherboards.
AMD Chipset platforms:
According to my knowledge there is no TRIM in RAID0 support for AMD RAID systems.
Intel Chipset platforms:
TRIM is
natively passing through the Intel RAID Controller into the SSD RAID0 array, if
a) the system has an
Intel Chipset from 7-Series up,
b) within the mainboard BIOS there is an
Intel RAID ROM resp. EFI SataDriver from v11.x.x.xxxx up and
c) an Intel
RST RAID driver from v11.x.x.xxxx up is running.
Users with an old
Intel Chipset system from P965 (ICH8R) up can benefit from the TRIM in RAID0 feature as well, if they have inserted an
especially TRIM modded Intel RAID ROM/EFI SataDriver module into their mainboard BIOS.
