No! SMART information goes through IRST 10.* (and older) because it implements CSMI (Common Storage Management Interface) which includes pass-through functionality for ATA commands. This nice feature allows Intel SSD Toolbox (and third party tools like smartmontools) to access SMART info and provide other functionality (optimizer, firmware update) even for drives in a RAID configuration.
My question was whether this is still the case for the IRST 11.2.* version you recommended.
