A method is disclosed for performing high speed disk I/O operations on PM data collected from a telecommunications system, including the steps of maintaining predefined tables in RAM, each having rows of logical disk blocks representative of predefined contiguous data locations in disk corresponding to the PM data for components and/or functions of the telecommunications system and one or more monitoring intervals, presenting the tables to a telecommunications application, receiving, from the application, a signal requesting a range of rows from one of the tables on which to operate a read or write, locking, in response to the request, the range of rows at the table level, ensuring that the requested logical disk blocks encompassing the range of rows is in a cache, locking the requested logical disk blocks in cache for a read and/or write operation, performing the read or write operation from the cache, automatically unlocking the requested logical disk blocks, and placing the requested logical disk blocks in a queue of the cache for later flushing to disk.
