A. Supports mission rates of SAS/6.0Gbps, 3.0Gbps, 1.5Gbps. B. Offers a throughput of up to 5Gbps when used with a USB 3.0 host and device, which is 10 times the capability of USB 2.0. C. Only SFF-8482 SAS hard disks are supported, and SFF-8639 U.2 hard disks are not supported. D. The card requires a 12V/3A DC5.5x2.1mm plug power supply. The power supply is not included in the package and needs to be purchased separately if not available. E. This adapter has a built-in chip that can convert a SAS disk to the USB interface of a common motherboard, allowing USB computers to use the SAS disk without the need for any SAS card. F.
