I just returned an OCZ Agility 2 that I had installed in an opti-bay. Unfortunately I could not update the firmware. When you take the optical drive out and put it in a USB enclosure the optical drive behaves differently and is no longer a bootable device (restarting and holding option or C). You also can't seem to be able to use a USB flash drive as well. Just wondering if there is a manufacturer out there that offers an OSX firmware updater that does not require windows and bootcamp (I just cant afford another operating system just to update firmware). I was thinking OWC, but apparently there solutions require you to boot into windows using bootcamp. Funny, because they offer the data doubler. I guess the only solace with them is that they say they haven't needed to update the firmware of the Mercury Extreme pro 3g for over a year. The whole reason I had to return the OCZ is that I was using it as a scratch disk in CS5 and it was giving me a pinwheel doing the simplest of tasks (working with low resolution images, never happened before with the traditional hdd).
