Apple Doubles MacBook Pro R/W Performance

Lucas123 writes Benchmark tests performed on the 2015 MacBook Pro revealed it does have twice the read/write performance as the mid-2014 model. Tests performed with the Blackmagic benchmark tool revealed read/write speeds of more than 1,300MBps/1,400MBps, respectively. So what's changed? The new MacBook Pro does have a faster Intel dual-core i7 2.9GHz processor and 1866MHz LPDDR3) RAM, but the real performance gain is in the latest PCIe M.2 flash module. The 2014 model used a PCIe 2.0 x2 card and the 2015 model uses a PCIe 3.0 x4 (four I/O lanes) card. Twice the lanes, twice the speed. While Apple uses a proprietary flash card made by Samsung, Intel, Micron and SanDisk are all working on similar technology, so it's likely to soon wind up in high-end PCs.

You can upgrade your 2014 MBP

[Chaset]

According to this: http://blog.macsales.com/25878... OWC put a 4x PCIE SSD from a mac pro into a 2014 MBP and got the extra performance gain. i.e. the 2014 MBP has 4x PCIE wired to the connector, but by default ships with a 2x PCIE SSD. They expect to ship SSD upgrades for MBP "soon", so you're not out of luck if you have the previous model.
