s Sakkura stated. Only count the time from "Start loading OS" to time to open first program. (Omit any time "on hold" waiting for a pass word.
Yes, Installation should be done with ALL other HDDs disconnected, and BIOS set to AHCI.
Recommend Downloading AS SSD benchmark, do not need to run benchmark, just open the program and look at upper left. It should show:
.. SSD make/FW version/formated size. Should always have the latest Firmware for the SSD, and it is also recommended that the latest system Bios update be used.
.. Will show driver, should initially be msahci, if This is intel based system down load the latest Intel chipset driver (iaSTor) which is slightly better than the defaul MS driver. If it is in IDE mode it will show pcide=BAD, which says it all.
.. Should also show partition alignment = OK.
Just as a side note, ignore comments about sata II vs Sata III. The Agility III is really (performance wise) a SATA II SSD cloaked in a SATA III dress. That is it performance is NO better on SATA III than it does on SATA II. This was addressed in a Review, and I confirmed on my systems - Have two 120 gig Agility IIIs.
