Connect a 2.5-inch SATA hard disk or SSD to a computer via USB 2.0 SATA to USB 2.0 Conversion Cable Features: Allows you to connect a 2.5-inch SATA hard disk or SSD to a computer via USB 2.0. The cable length is approximately 42cm. The USB cable is split into two, providing a stable power supply and preventing power shortages. (One of the split cables is for data + power, the other is for power only) The USB output from a computer is 500mA, but by using the split cable, it becomes 500 + 500 = 1A. On computers with a good power supply, it can operate with only one USB connection. This product is exclusively for 2.5-inch SATA hard disks or SSDs. It cannot be used with IDE, SCSI, or other hard disk/SSD standards. 3.5-inch hard disks require 12V power and cannot be used. (This product only supports 5V from USB bus power.) While it can be used with most hard disks and SSDs, it cannot be used with hard disks that require more than 5V1A of power.
