PCIe vs NVMe
Hi All,
I've been a PC guy since 1984, but I'm planning to switch to Mac later this fall or perhaps next spring, depending on when the MBP is updated with Skylake, and I'm trying to figure out Apple specs. Perhaps you can help.
As you know, the current MacBook Pro has "PCIe-based Flash Storage," whereas the new MacBook has the brand new NVMe specification to access the SSD, which is apparently much faster. Or so they say. Does anyone have any numbers to show how much faster? And how fast is the current PCIe standard in a Mac?
For example, in my old PC using AHCI to access an SSD, data transfer tops out at about 500 MBps because of the AHCI bottleneck. The SSD is much faster, but it's limited by the AHCI controller. NVMe is coming online now and I've read it will transfer data at about 2 GBps which removes the bottleneck because it's faster than the SSD. Way cool! So how fast is PCIe on a Mac and how fast will NVMe be when it arrives in the MacBook Pro, which I'm guessing will be soon?
Any advice or explanations will be greatly appreciated. Many thanks.
Cheers,
Dave
