Over at TekRevue, Jim Tanous has revisited the use of a RAM disk on two new Macs, a 2013 Mac Pro and a 2014 MacBook Pro. He reports that, "The 2013 Mac Pro features extremely fast PCIe-based flash storage, but it’s no competition for the speed of a 32GB RAM Disk. The internal flash storage hits around 1,200MB/s reads and just shy of 800MB/s writes, but the RAM Disk peaks at 4,800MB/s reads and 5,100MB/s writes. 5.1 Gigabytes per second. Nice." Of course, the RAM disk eats into the available RAM so it's geared for specialized applications that can really use the boost. But it's also volatile, so reboot or lose power and it goes poof. Even so, check out TekRevue's tantalizing tutorial and amazing benchmark tests.
