Context: <response>: ```Firstly, dem bin think am and still dey use am till today for optical storage devices (CD-RW drives, DVD drives, etc.), plenty manufacturers dey offer external portable USB hard disk drives, or empty enclosures for disk drives. Dem dey offer performance wey dey compare to internal drives, but e dey limited by the current number and types of attached USB devices, and by the upper limit of the USB interface (in practice about 30 MB/s for USB 2.0 and potentially 400 MB/s or more for USB 3.0). These external drives typically include a "translating device" wey dey bridge between a drive's interface to a USB interface port. Functionally, the drive dey appear to the user much like an internal drive. Other competing standards for external drive connectivity include eSATA, ExpressCard, FireWire (IEEE 1394), and most recently Thunderbolt.```
