Raid0 and TRIM Support on Intel 11.5 OROM and Latest v11.5.0.1184 RST Drivers ?

[Marc HFR]

The simpliest way to verify if TRIM is working is with WinHEX

1/ Copy a JPEG file (for example) to the root directory of your RAID
2/ Open WinHEX then press F9 (Open Disk) then choose your RAID partition
3/ Choose your files and look at his content, note the first cluster / offset
4/ Then delete the file under Windows
5/ Under WinHEX press F9 to reopen your partition and choose "Take a new one"

=> When you choose your (deleted) file you must see 00 00 00 or FF FF FF (etc.) instead of the old content. If the content did not change then TRIM is not ok.
=> If the file is not here use alt+g or ctrl+g to go to the good location and see if you got 00 00 00 or FF FF FF (etc.) or the older data

One SSD, AHCI, RST 11.2 : ok

Two SSD, RAID 0, RST 11.5 : bad

But for the moment i don't have a bios with ROM raid 11.5.0.1414 for my motherboard
