What I would suggest is buying a 3DS AC adapter for your region, fully charge your system, and see if you notice anything weird about the battery life.
So, I have an iMac 21.5" late 2013 with a 1 TB hard drive. If I install a PCIe 2.0 x4 flash array in the empty PCIe slot on the logic board, what additional steps are needed to have the iMac treat the HDD and flash as a single fusion drive?
