Key Features:
4-Port SATA III (6Gbps) Expansion
Adds four high-speed SATA III ports to a system via a PCIe x1 slot.
Supports SATA III (6Gbps), SATA II (3Gbps), and SATA I ( 1.5G bps) devices.
PCIe x1 Interface
Connects to a PCIe x1, x4, x8, or x16 slot (backward compatible).
Uses a single PCIe lane (v 2.0 or higher recommended for full bandwidth).
Hardware RAID Support
Supports RAID 0, 1, 5, 10, and JBOD (varies by controller chip, e. g., ASMedia or Marvell).
Optional RAID functionalitysome cards may require software RAID (OS-dependent).
Performance
Max theoretical bandwidth per port: 6Gbps (~600MB/s).
PCIe x1 (v 2.0 ) provides ~500MB/s total bandwidth, which may bottleneck all four ports at full speed.
Compatibility
Works with HDDs, SSDs, and optical drives.
OS Support: Windows (7/8/10/11), Linux, macOS (driver-dependent).
Additional Features
Low-profile bracket may be included for small-form-factor PCs.
Plug-and-play in non-RAID mode.
Use Cases:
Expand storage in PCs with limited onboard SATA ports.
Create a RAID array for performance (RAID 0) or redundancy (RAID 1/5/10).
Ideal for NAS, servers, or workstations needing extra SATA connectivity.
