I'm sure I'll sound like a noob on these questions but being new to the fusion drive technology. Is there any way (or an app) to determine what's currently on the flash portion of the drive? Also is anyone tempted to split up the fusion drive and run a traditional physical layout, i.e., one flash drive and another hard drive arrangement. If so what's the advantages of that? So far I'm happy with how my iMac is performing, and the 2TB Fusion drive is fairly quick - other then running it in windows. Booting up on that is SLOOOOWWWW, but that makes sense since the OS is sitting on the 5400 rpm drive.
