I bought a Samsung EVO 860 1tb SSD last fall to use in my MacBookPro (15”, late 2011), which is now dying, and now my iMac (27”, late 2012) needs a new HD, so I thought I would take this drive out of the MBP and use it in the iMac. I have the iFixit kit for iMac SSD installation, so the last step is confirming which SSD to use.

Before installing, I wanted to do some testing using Black Magic Disk Speed Test, here are the results:
iMac Fusion Drive (HDD+SSD):
Write: 150-200mb/s
Read: 250-400mb/s
Samsung 860 EVO:
Write: 30-50mb/s
Read: 220mb/s
So my question is, what’s going on here? It makes no sense at all that the fusion drive tests results are beating the pants off the EVO, which is giving worse results than just about any HD I can recall testing. I did test the speed via Thunderbolt 1 using Target Disk Mode, but also got similar results directly on the MBP that houses the EVO. The SSD is pretty full, would that have a drastic affect on the speed? Is this thing just bad?
