I've previously installed a dual 2.5" adapter bracket inside my 2nd optical drive bay to accomodate two SSDs. Works great except I didn't know that TRIM wouldn't be enabled for the SSD connected to my SATA PCIe card. So now I've decided to move that SSD to a regular Mac Pro drive bay and then move one of my hard drives to the optical bay and connect it to the SATA PCIe card (as it doesn't need to be bootable nor have TRIM support). This would give both SSDs TRIM support. The thing I'm struggling to find is an adapter bracket (5.25") which takes a hard drive (3.5") and an SSD (2.5"). Are brackets like that available?
