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 mean like any other technology purchase :(

I know it's a little late, but for your next apple purchase (if there is one) be sure to check:

They generally stay on top of most of the rumors surrounding new product launches. Well enough to know if it's worth waiting for a few months before buying the new model or holding out till the next big Apple event.

Semicolons!

What a missed opportunity for a semicolon after "Samsung", and what a confusing sentence as a result.

Four times the speed not twice.

"Twice the lanes, twice the speed"...man someone doesnt understand the PCIe standard or how to do simple math. Its actually twice the lanes, FOUR* times the (theoretical) speed. 2x500MB/s vs 4x985MB/s * rounded up
