Apple has it as “up to 2.6GB/s sequential read and 2.7GB/s sequential write.” That’s slower than a 970 PRO or EVO. I’d love to know the 4K IOPS at low queue depths. Thinking maybe get the 256GB option and never use it. Drop in Samsung’s and maybe even an Intel 905p for working drive. Anyone have thoughts on this? I’m sure the 256GB -> 1TB option will cost more than a 1TB 970 EVO.
