In this article, we present a deeper understanding of everyday data cultures in regards to personal information management practices. We draw on a study involving 14 in-depth interviews with users of portable hard drives and USB portable flash drives in Melbourne, Australia, to examine participants’ reflections on their management of personal information on USB portable devices. In examining participant use of these devices, we consider how they kept (stored) and organized (arranged) information on these devices. We also examined device and data sharing. We conclude by thinking about their increased use within cross-tool information management, including the nexus of portable hard drive/USB use and cloud storage. The argument of this article is that portable hard drives and USBs, due to their miniaturization, ease of portability, affordability and storage capacity, add considerable complexity to established understandings of personal information management practices.
