Most hard drives and card readers that you'll get thrown at you as a digital loader will be USB3 or Thunderbolt. The drives from client will need to be formatted as Mac OS Journaled 99.99% of the time.
In terms of software, you'll be expected to have and be able to run at a minimum Shotput Pro, Adobe CC, Final Cut Pro X, and Davinci Resolve 12. Once you get onto bigger jobs, there will be other software solutions expected like Silverstack.
Expect to also purchase a 600-1500w UPS, a Sonnet Expresscard SxS Thunderbolt reader, a USB3 CF/SDHC multi-card reader, a USB3 CFast reader, extra Thunderbolt cables, extra USB cables, Thunderbolt to FW800 and Ethernet adapters, some sort of eSATA solution, and a 25' stinger. If you go on to do some DIT work and require SDI output out of the laptop, a Blackmagic Mini Monitor is a good thing to have in the bag.
So just get a top spec 15" Retina MacBook Pro with maxed out RAM. Or a 13" if you're really on a budget. Anything else is not worth the hassle. Once you get into real DIT work with transcoding, creating looks and LUTs, and require a calibrated SDI monitor, you'll need to upgrade to a Mac Pro or two.
