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 :(
You bought a Haswell-based MBP knowing full well that Broadwell had been released and would work its way into the MBP line shortly.
You also ignored the fact that Apple has been updating the Retina MacBook Pros like clockwork.
If you're miffed, be miffed at yourself. Nobody hid this from you.
What a missed opportunity for a semicolon after "Samsung", and what a confusing sentence as a result.
I'd check the benchmarks on real work you might be doing. Unless you're doing some very specific unusual tasks, doubling the continuous write and read speeds over an already fast SSD won't gain much.
Doubling performance of one subsystem only counts as 'doubling performance' against specific workloads(of which there are some, hence the enthusiasm among users of Big Serious Databases for buying SSDs that cost substantially more than this laptop, or even a pallet of these laptops, once you get the whole storage system up and running); but your usual laptop activities probably won't be quite as dramatic.
What is somewhat notable about this change is that these days are the first time in ages that storage systems(outside of contrived scenarios involving hanging gigantic fiber channel arrays off the lousiest PCI-X HBA you can find, then adding a cheapie PCI device to the same bus just to cut the bandwidth further, or similar silliness) have actually been bottlenecked by their connection to the rest of the system, rather than by their own inadequacy.
With HDDs, and the earlier SSDs, the alleged link speed was a mostly theoretical value that determined little except how fast you could access the drive's cache RAM. Now, it seems, adding a couple of extra PCIe lanes can actually double performance. Not bad at all.
So you can hook up to an external monitor OR charge your Iphone OR make a powerpoint presentation! In 2016, it will be even lighter when they reduce the number of letters in the alphabet for the keyboard.
