The data density of magnetic disk has been growing at 30% to 50% per year. However, physical limitations will slow this growth unless creative recording techniques can be found. Shingled writing is a promising technique that trades off the inability to update in-place for narrower tracks and thus a much higher data density. In this paper, we(More)
Analyzing the performance and power of Mobile Internet Devices (MID) is important for academia and industry as well as for consumers. It is important to assess the performance associated with a typical workload on MIDs so that applications and hardware can be optimized to reduce performance bottlenecks. In this paper, we present TMAPP, a benchmark developed(More)
Shingled Disks and Arrays – Disk drives have seen a dramatic increase in storage density over the last five decades, but to continue the six orders of magnitude growth seems difficult if not impossible. One promising approach to overcome the impending limit is shingled magnetic recording (SMR). It’s particularly appealing as it can be adopted while(More)
Disk drives have seen a dramatic increase in storage density over the last five decades, but to continue the growth seems difficult because of physical limitations. One promising approach to overcome the impending limit is shingled magnetic recording (SMR). It can be adopted while utilizing essentially the same physical recording mechanisms currently in(More)
