Model: PCE8SAT-M01, Master: Fit for Marvell 88SE92xx+JMB5XX, Interface: PCI-E 1X 2X 4X 8X 16X, Support System: Fit for 7/8/XP/10 Fit For Ubuntu, Expansion Interface: 8 x SATA3.0 Interfaces. Key benefits - Expand storage with 8 x SATA3.0 ports for desktops and workstations, enabling additional drives for data, backups, or media libraries. - Flexible PCI-E compatibility across slots from 1X to 16X, supporting a wide range of motherboard designs. What it offers - 8 x SATA3.0 interfaces for direct drive connections, plus full compatibility with SATA 3.0, and backward compatibility with SATA2.0 and SATA1.0. - Supports communication speeds of 6.0 Gbps, 3.0 Gbps and 1.5 Gbps; supports Gen 1i, Gen 1x, Gen 2i, Gen 2m, Gen 2x and Gen 3i. - Supports AHCI1.0 mode and IDE mode, native command queue (NCQ), FIS based on port multiplier switch or command switching, and hot plug. Setup and compatibility notes - BIOS / motherboard setting: SATA mode should be set to AHCI. Some PCI-E 2.0 boards do not enable the Gen2 high speed mode by default and require manual activation. In PCI-E 1.0 mode the speed is typically 200–250 MB/s; PCI-E 2.0 mode can be below 350–400 MB/s. If these limitations are unacceptable, consider a different motherboard. - Wide compatibility: PCI-Express v2.0 compatible and backward compatible with PCI-Express v1.0; compatible with SATA6G, 3G and 1.5G drives. For best results, use a SATA3.0 data cable. Use scenarios - Add multiple drives to a desktop PC to increase data storage, backups, or media libraries without changing the motherboard. - Upgrade older systems with limited SATA ports by providing eight additional SATA connections while maintaining compatibility with AHCI and NCQ. - Install in workstations or home servers that require hot-plug capable storage expansion with broad speed support.
