Another issue I have is--how to migrate my debian system from the old original SSD to the new larger SSD? As for macOS [1], it should be easy. There is a macOS application called Time Machine that allows to backup macOS from the old SSD and to restore it to the new SSD. This would work with a

Hi, I've got a compatibility question regarding SSDs. I run debian 9.6 on a MacBookPro12,1 (Early 2015, 13"). I'm thinking of upgrading the stock 128 GB SSD [1]. Specifically, I'm considering the Trascend JetDrive 850 [2]. The original SSD uses a PCIe 3.0 x4 interface and the AHCI protocol.
