The reviews of the M1 MacBook Air and Pro show a dramatic increase in SSD read/write speeds over the 2020 Intel models.
- kllrnohj 6y agoDo you have a link? MKBD just said it was "slightly faster" than his comparison system and the numbers for the M1 appear to be around 3GB/s reads and 2.7GB/s writes in disk speed test, which is pretty typical of a last generation NVME drive (current pcie gen4 drives are hitting 7GB/s reads & 5GB/s writes)
- chongli 6y agowhich is pretty typical of a last generation NVME drive Those numbers are about 2-3x as fast as what my 2020 Intel-based MacBook Air gets.
- kllrnohj 6y agoThen sounds like Apple put some really garbage SSDs in the 2020 Intel-based Air, not sure what you're looking for here? But 2-3x won't change swap from grinding to a halt to perfectly smooth, either. It's still over 20x slower than RAM. More significant for swap usage though is random reads and read latency, neither of which are going to be particularly impressive on the M1's SSDs. You need something like Optane to make that a compelling case.
