Hi, thank you for your reply. I am aware about IT mode being requested to get Trim functionnality but I was asking more specifically about Trim availability in conjunction to Raid 10 (when IT mode, P16 bios and deterministic reads after TRIM SSDs are used).

Does older HBAs firmware ( p16) in addition to SSD DRZAT support only makes Trim work in JBOD mode or can it also work with other RAID modes such as RAID10 ?
