1. ASM1061 PCI Express SATA-3 expansion card can use the latest and fastest 6Gb/s hard disk in the industry. At the same time, it is backward compatible with traditional SATA 1.5Gb/s or SATA 3Gb/s drives. It uses the same cables and connectors as previous of SATA to simplify integration 2. ASM1061 PCI Express is a single-chip SATA expansion card, from PCI Express to two SATA Gen III 6Gb/s channel host controllers, providing server-level functions for desktop computers 3. In addition, PCI Express 2.0 has twice the bandwidth of the existing PCI Express bus, enabling faster data throughput. It enhance system performance for every type of computer user. Each PCI Express 2.0 channel can provide up to 500MB/s throughput. It is also backward compatible with the previous generation PCI Express 1.0 technology 4. PCI Express requires a slot of V2.0 or higher. The speed of V1.0 not exceed 250M. Whether PCI Express is X1 or X16, as long as it is the V2.0 version, the free X16 slot can be directly inserted into the X16 slot. 5. Motherboard BOIS setting: SATA mode should be changed to AHCI, although some motherboard PCI-E is version 2.0, but BOIS does not enable high-speed transmission mode by default (Gen2 high speed mode) needs to be manually turned on 6. XP / Vista / Win 7 / Win 8 / Server 2003 / Server 2008 R2./Linux 2.6.x and higher, one available PCI Express slot Specification: Name: PCIe SATA 3.0 expansion card Chip: ASM1061 Data transmission speed: 6000Mbps PCB Size: 67 x 68mm Product weight: about 45g colour:Black Material:ABS+Metal Package Contents: 1 x PCIE SATA3.0 Expansion Card Only the above package content, other products are not included.
