OMG! OMG! You're so dumb!!I have no idea why deviant's statement was even the least bit controversial. You couldn't possibly afford a 50TB NAS storage filled with SSDs. Is it THAT hard to understand? I hate to read this stuff over and over again.

HDDs are for storage, SSDs are for the system. Intel expects NVMe to also be coming to tablets and phones in the near future.Īnother nail on the HDD cofin. Going into the future, NVMe will allow Apple's hardware to take further advantage of the performance of SSDs as well as improve battery life with less time spent transferring data. Apple has already upgraded the physical interface to the much faster PCIe connectors a number of years ago. The new protocol is not to be confused with the underlying hardware that connects the SSD to Apple's notebooks.

The result is NVMe, short for Non-Volatile Memory Express. As a result AHCI can't take full advantage of SSDs and since the future is in non-volatile storage (like NAND and MRAM), the industry had to develop a software interface that abolishes the limits of AHCI. While that doesn't rule out SSDs, AHCI is more optimized for high latency rotating media than low latency non-volatile storage. Anandtech offers a good overview between the technologies:ĪHCI (Advanced Host Controller Interface) dates back to 2004 and was designed with hard drives in mind. The NVMe software interface replaces the AHCI software interface in Apple's previous notebooks, and offers improved latency and performance over the old protocol.
