Promise Technology manufactures ATA and SATA (RAID) controllers, which usually feature Promise chips for the device interface and nearly always no RAID CPU, therefore they are "soft-RAIDs" (except the higher-priced models).

Stay away from the Promise-based (PDCxxxxx) IDE-Controllers under Linux (and probably other Opensource OS too). They WILL cause (mostly silent) data corruption. Get a Silicon Image based controller instead (Dawicontrol DC-133 for example).
