dio is a commandline utility that can generate reads and/or writes to a raw device, a file, or to memory. It supports large files, variable block sizes, configurable seek lengths between I/Os, and initial offsets. Most conveniently, all sizes and offsets can be specified using simple infix expressions. All I/O operations are timed, so dio can also be used to create custom I/O benchmarks. GUI:Нет Терминал:Есть Windows альтернатива : Программные требования : Аппаратные требования :
