PCIe-based solid-state disks are all the rage these days, and a new one from a company called Angelbird offers interesting expansion potential. Simply dubbed Wings, the PCI Express x4 card starts at $239 and comes equipped with 16 or 32GB of flash memory. To that card, users can add up to four ArchWing expansion drives, which look to be little more than standalone SSDs. Those drives use SandForce SF-1200 controllers and come in 120 and 240GB capacities.
Expansion isn't limited to ArchWings, though. Users will be able to add their own 2.5" hard drives or SSDs using "universal clip & couplers" that come bundled with the Wings card. It looks like you'll have a fair amount of control over how those drives are configured using the Wings card's integrated RAID controller, as well.
Angelbird says the Wings card can boot Windows, OS X, and most Linux distros. The company makes some pretty impressive performance claims, too. With a 32GB Wings card and just one SSD, users can expect 285MB/s sustained reads and 275MB/s writes. Throw four SSDs into the mix in what I assume is a striped RAID 0 array, and you're looking at 1081MB/s reads and 945MB/s writes.
Wings cards are currently in production, but there's no word on when they might become available for sale. Thanks to Engadget for the tip.
