Direct PCIe Connections Help MacBook Air SSDs Tout Blazing Read/Write Speeds
Aside from Apple touting the ďall-dayĒ battery life that comes alongside the upgrade to Intelís Haswell processors in the new MacBook Air, one of the major improvements is the adoption of PCIe-based flash storage for much faster performance. The new PCIe flash will be coming to Appleís radically designed Mac Pro as well later this year and Apple is likely to introduce it in other Macs as well going forward. The folks over at AnandTech have taken a closer look at the flash storage performance and other benchmarks for the new MacBook Air, finding that read/write speeds are approaching a whopping 800 MB/s. They had the following to say regarding the matter:
Available in capacities up to 512GB, this next-generation flash storage is up to 9x faster than a traditional 5400-rpm notebook hard drive. And itís up to 45 percent faster than the flash storage in the previous-generation MacBook Air. So when you flip open MacBook Air, itís ready to go right away. Even after a month in standby mode, the screen springs to life.
The drive in my system uses a Samsung controller, although I've heard that SanDisk will have a PCIe solution for Apple as well. A quick run through Quick Bench reveals peak sequential read/write performance of nearly 800MB/s.
This is a pretty big deal, as it is probably the first step towards PCIe storage in a mainstream consumer device that we've seen.
Seeing such benchmarks being achieved definitely brings a warm fuzzy feeling to any techieís heart!
