pls help this is pretty urgent.
i would like to know the max capacity of ext hard disks being sold that's just plug-and-play and without needing any ext power supply.
if i'm not wrong it's 2.5" ones only. i've checked out challenger and the max seems to be 250gb.
are there those with even more storage? and what are the prices like? where should i get it from? sim lim?
all help appreciated thanks!
