Twochannel PCI Express 2.0 based SATA controller card Key benefits Enables storage expansion with two SATA interfaces operating at speed, suitable for adding fast storage to a desktop or workstation. Supports SATA 6 Gbps devices (SATA 3.0) while remaining backwards compatible with SATA 1.5 Gbps and 3.0 Gbps devices. Provides programmable transmitter signal level for flexible signal integrity tuning. Includes IDE and AHCI programming interface registers support for controllers, enabling broad compatibility with existing software and drivers. Complies with Serial ATA 3.0 specifications for messaging and interrupts, ensuring reliable communication with compatible drives. Uses a PCI Express 2.0 bus to deliver solid performance with modern SATA devices. Key specifications Interface: 2channel PCI Express 2.0 Data transfer capability: up to 5.0 Gbps total (up to 2.5 Gbps per PCIe channel) Supported controller interfaces: IDE programming interface registers; AHCI programming interface registers Signal handling: Programmable transmitter signal level Drive compatibility: Supports SATA 6 Gbps devices in line with SATA 3.0; backwards compatible with SATA 1.5 Gbps and 3.0 Gbps devices Compliance: Serial ATA Specification 3.0; supports Message Interrupts What this card does Provides two SATA channels via a PCIe 2.0 bus, enabling additional speed SATA storage connections without upgrading the motherboard. Delivers reliable AHCI or IDE mode support to match differing controller requirements and software environments. Compatibility and performance considerations Works with SATA III (6 Gbps) drives for maximum throughput, while maintaining compatibility with older SATA speeds (1.5 Gbps and 3.0 Gbps). Designed for use in desktop and workstation environments where additional storage capacity or performance is needed without changing existing PCIe configurations. 23 practical use scenarios Desktop performance upgrade: add two speed SSDs to accelerate the operating system, applications, and boot times in a gaming or productivity PC. Home or small office storage expansion: attach additional drives to a compact workstation or home server to increase available storage for backups, media libraries, and data archiving. Content creation and editing workflow: connect extra SATA drives for media asset storage, cache, or project files to improve performance in video or audio production environments.
