Japanese company Orange Systems announced a new modular PCI Express SSD, the "Wings" series, which is a collection of products: the PCIe SSD card, its SSD subunits that have to be purchased separately, and those subunits in hard cases that turn them into 2.5-inch simple SSDs. To begin with, Angelbird has three PCIe SSD main card variants: "Lite", 16 GB, and 32 GB. These cards are basically PCI Express x4 SATA 3 Gb/s RAID cards that have SATA power+data interfaces on the card. The 16 GB and 32 GB cards have a localized SSD subunit on the board, while the "lite" variant has no localized subunit, and relies entirely on attached subunits.

These subunits are basically 2.5-inch SSD PCBs stripped of their cases, which Orange Systems refers to as Wings Expansion Cartridges, which are basically SandForce SF-1220 driven SSDs with MLC NAND flash, available in capacities of 60 GB, 115 GB, and 240 GB. When attached in pairs to the Wings PCIe SSD card, the card's main controller runs them in a RAID 0 configuration that is abstract to the host, delivering increased performance. Lastly, these "Expansion Cartridges" are available with their outer shells, branded as "Crest SSDs".The Lite, 16 GB, and 32 GB Wings PCIe cards are priced at 25,095 JPY ($327), 30,345 JPY ($395), and 36,645 JPY ($477), respectively; the 60 GB, 115 GB, and 240 GB expansion cartridges are priced at 17,745 JPY ($231), 26,145 JPY ($340), and 63,945 JPY ($833), respectively; and the derived Crest SSDs (these subunits with their cases, as 2.5-inch SSDs), cost the same for each capacity.
