The best way to accomplish the department's goals is to transfer the existing data to an external eSATA enclosure, which is a device that connects an external hard drive to a computer using an eSATA port. This will allow the accounting department to retain the current data for quick read-write access, as eSATA provides high-speed data transfer rates and supports hot-plugging. Unlike USB 3.0, eSATA does not share bandwidth with other devices, which can improve performance and reliability. Verified References: [eSATA vs USB 3.0]
