Chosen Solution
I know this is an older laptop. But, I recently found this M.2 to SATA adapter that can house 2 M.2 blade SSD’s: Dual-M-2-SATA-Adapter-RAID This got me thinking, would it be possible to install 4 blade SSD’s in two of these adapters if I were to replace my current HDD and the optical drive with the OWC Data Doubler?
Sadly a day late and a dollar short ;-{ While this is a plausible solution for the primary drive it won’t work terribly well on the optical bay. You see the your system has a limitation within the optical drives SATA port as you can see here OWC Data Doubler reference your system from here: MacBookPro8,2 You’ll see your optical drive’s listed I/O speed is SATA III (6.0 Gb/s) but needs a SATA II (3.0 Gb/s) based drive. Auto sense drives won’t work, and this adapter unit is likewise auto sense so it won’t work either. Now getting into this a bit deeper, you’ll see the unit requires the older mSATA based M.2 SSD’s which are not very fast or offer larger sizes (4-8 TB). The newer 2.5” SSD’s are faster and cheaper than these older 2230, 2242, 2260, 2280 M.2 Samsung SSD’s. And the adapter does not support the newer better M.2 NVMe or AHCI PCI-Express SSDs.
