Supports SAS data transfer rates of 6.0Gbps, 3.0Gbps, and 1.5Gbps. Offers a throughput of up to 5Gbps when used with a USB 3.0 host and device, up to 10 times the capability of USB 2.0. Compatible only with SFF-8482 SAS hard disks; SFF-8639 U.2 hard disks are not supported. The card requires a 12V/3A DC 5.5x2.1mm plug power supply (not included); power supply must be purchased separately. Built-in chip enables conversion of SAS drives to standard USB interface, allowing USB-enabled computers to use SAS hard disks without requiring a SAS controller card. Connect the adapter to your USB interface to directly read and write SAS hard disks; compatible with Windows 7, Windows 10, and Windows 11. After conversion, SMART information for the SAS hard disk may display incompletely or not at all, but this does not affect normal read and write operations.
