i use sony optiarc laptop drive witha usb to sata cable. $50
I guess if internal laptop drive + faceplate + SATA to USB is a nice ghetto solution if the price is justified.
in 2015 I wanted one, so I searched on ebay and found a seller novoshipping selling. Back then less than sgd $60 so I buy. Now all quite expensive. The model I have is 5550H.
