Actin filaments and microtubules lengthen and shorten by addition and loss of subunits at their ends, but it is not known whether this is also true for intermediate filaments. In fact, several studies suggest that in vivo, intermediate filaments may lengthen by end-to-end annealing and that addition and loss of subunits is not confined to the filament ends. To test these hypotheses, we investig...

In this paper, we examine two modern enterprise Flash-based solid state devices and how varying usage patterns influence the performance one observes from the device. We observe that in order to achieve peak sequential and random performance of an SSD, a workload needs to meet certain criteria such as high degree of concurrency. We measure the performance effects of intermediate operating syste...
