Quoted: Lime Technology believes that there is a market for a new wrinkle on the old RAID technology. Our approach uses a storage organization we call unRAID™. unRAID™ is similar to RAID-4 in that for every n hard drives, there are n-1 data drives, and a single fixed parity drive. Unlike other RAID organizations, however, files are not striped across the data drives. Instead, each data drive is formatted normally with its own file system.
