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

Oh I did not realize that. Is that why 11.2 is faster for raid? But on the other hand 12.7 is much faster than 11.2 with a single drive.

I don't know the exact reason, but I suspect, that the Intel RST driver v11.2.0.1006 has been optimized for Intel RAID0 systems.

But on the other hand 12.7 is much faster than 11.2 with a single drive.

The measurable performance differences are quite small, if you compare different Intel RST and RST(e) drivers in AHCI mode, but remarkable, if you do the same with a RAID0 system.
I have posted such a comparison of different AHCI and RAID driver version within the second post of >this< thread.
