Chosen Solution
What maximum speeds can be achieved by changing the SSD to for example, Samsung 970 EVO 500 Gb to M.2 in iMac 5k 2014 using adapter e.g. Sintech NGFF M.2 PCIe SSD. Thank you
The fastest SSD you can use on your Mac is an external unit! via Thunderbolt2. OWC ThunderBay 4 RAID Loaded with Samsung SSD’s! I get 1 TB of throughput! If you want something internally, then the fastest drive is Apple custom Samsung SSPOLARIS PCIe 3.0 x4 interface SSD It uses the same flash chips and controller the 970 EVO uses! I really don’t recommend using M.2 SSD’s and these adapters. I’ve got a drawer full of dead ones I’ve pulled out of systems. Given the amount of work to open an iMac I really recommend sticking with a real Apple unit or go with either OWC or Transcend SSD’s which are designed to work in your Mac. In a MacBook Pro that at least is an easy replacement.
Thanks for the details. But simple question is, I need max SSD speed from a late 2014 iMac. What is the fastest solution? The Apple drive seems not support or more likely will run at 1/2 speed since there are 2 lanes. Not sure how TB2 (even raid) could reach those speeds. Please clarify.
