> The PCIe interfaces SSDs that Apple's been using allow really fast speeds of upto 3Gbps, which is almost double those offered by other interfaces like M2 or even more faster than SATA. Nonsense. NVMe is an industry standard, M.2 supports it, just like many SSDs. A Samsung 970 Pro SSD does 3.5 GB/s (not Gbps; SATA II already did 3 Gbps well over ten years ago). Incidentally, Samsung 970 Pro SSDs come at a fraction of Apple's upgrade costs.
