Now that PCIe flash is being rolled out in an Apple desktop, one industry pundit said it is likely to come soon to the company's notebook computers. "This is a machine unlike anything we've ever made, both inside and out," Apple CEO Tim Cook said during his WWDC keynote today. By comparison, a top-rated laptop solid-state drive using a SATA II interface tops out at about 550MB/sec, about half that of the PCIe flash Apple will be rolling out. There's no translation layer required.Īpple, which announced that Mac Pro upgrade at its Worldwide Developer's Conference, said the new flash internal storage will offer astoundingly fast 1.25GBps reads and 1.0GBps writes. PCIe-based flash has far better performance than more typical SATA- or SAS-connected solid-state drives (SSD) or flash because of the direct connection to peripherals. PCIe, or peripheral component interconnect express, is a high-speed serial expansion card format that uses a point-to-point architecture. The new Mac Pro (right) design compared to older models Apple's new Mac Pro desktop computer, unveiled today, will be available later this year in a vastly smaller, and cylindrical box that adds PCIe flash storage technology, an upgrade that promises to boost performance by 10 times over the hard drives in current models.
