FIO-New!
FIO is an I/O tool meant to be used both for benchmark and stress/hardware verification. it has support for 13 different types of I/O engines (sync, MMAP, libaio, posixaio, SG V3, splice, null, network, syslet, guasi, solarisaio, and more ), i/O priorities (for newer linux kernels), rate I/O, forked or threaded jobs, and much more. it supports Linux, FreeBSD, NetBSD, OS X, opensolaris, Aix, HP-UX, and windows.
