The restaurant that Curtis and Paul meet up at is the same set for CC Jitters from The Flash.
Felicity says that the pocket data device captured a petabyte of data from Chase's mother's computer in a matter of a couple of minutes. A petabyte is 1 Million Megabytes, or 1 Thousand Terabytes. As of the time this episode was produced, disk drives of about 8 terabytes are about the largest commercially available, and memory sticks of about 2 TB are the present norm. So the target computer would have about 125 disk drives (not counting overhead for RAID), the pocket device about 500 thumb drives, and the data transfer would take a little over 18 minutes if it could be done at the full theoretical max Wi-Fi rate of 8 bonded 802.11 channels (ignoring any limitations of the data bus on the computer/device). So the devices used in the episode appear to be DAIFM technology.
