Last year, Apple made an important change to 80 percent of their Mac line-up, including the new iMac, MacBook Pro, Mac Air, and Mac Pro, that changed the type of flash storage of each of those systems to incorporate a PCI Express (or PCIe)-based storage system. It’s a much faster technology than the Serial ATA based storage Apple was using before, but there’s a rub: it also uses a non-standard connector, making upgrading any of these Mac’s flash storage impossible up until now.
At CES this year, however, it looks like Other World Computing (OWC) has made important strides to cracking the problem. They showed off flash storage prototypes that should enable users to upgrade their newer Mac’s SSDs.
