I am running out of space on my computer's internal storage (only about 2.2Gb left), which is rather a shame, since I have spent the afternoon taking photographs in the local park, and have nowhere to put them. What in the way of additional storage do people here who use additional storage prefer - an additional internal hard drive (I currently only use an SSD for performance and noise reasons), external hard drive(s), and, if the latter, USB, e-SATA or ethernet connected? I already have a backup drive connected via ethernet , but that is needed for backup: if I were to use that for primary storage of anything, I should have no backup should that medium fail. Also, I use Lightroom: how, especially if an external USB or e-SATA drive were used, would one go about telling the catalogue that many photographs were moving? How do those with external hard drives organise things?
