The Manhattan Hi-Speed USB to SATA/IDE Adapter with power supply connects SATA, SATA-enhanced, IDE and enhanced-IDE hard disks to desktop and notebook computers using a USB port. Transferring and sharing files between desktop and notebook computers, backing up files or storing large file archives on external drives is faster and easier to accomplish. Serving as a bridge, the adapter can transfer data between SATA and IDE external drives when both are simultaneously attached. Compatibility with all types of hard drives up to 5.25" - including 2.5" notebook computer drives and standard 3.5" hard drives - makes this a versatile tool for professional and home users.
