LogicalDisk|PhysicalDisk\Split IO/sec

Reports the rate at which the operating system divides I/O requests to the disk into multiple requests. A split I/O request might occur if the program requests data in a size that is too large to fit into a single request or if the disk is fragmented. Factors that influence the size of an I/O request can include application design, the file system, or drivers. A high rate of split I/O might not, in itself, represent a problem. However, on single-disk systems, a high rate for this counter tends to indicate disk fragmentation.
