scsiSpeedTest( )
This test initializes a block device for use with a dosFs file system. The test uses a
large buffer to read and write from and to contiguous files with both buffered and
non-buffered I/O.
scsiSpeedTest( ) runs a number of laps, and uses timex to time the write and read
operations. The speed test should be run on only one drive at a time to obtain
maximum throughput.
Invoke this test as follows:
scsiSpeedTest "scsiBusId devLun numBlocks blkOffset"
