In order to understand Apple’s decision to switch from the older Serial ATA (SATA) interface to the higher-performing Non-Volatile Memory Express or NVMe, we recommend reading Ramtin Amin’s excellent deep-dive into its implementation. The main advantages of using NVMe to provide SSD storage access are that by using all the available parallel operations possible with modern flash-based storage over a four-lane PCIe connection, much better I/O speeds can be achieved compared to older HDD-specific interfaces.
Kinda surprised that this needed an Apple-specific explanation. I mean, didn't all board manufacturers move toward NVMe simply because it's faster than ATA?
