reads and writes per second

Hi folks,
How to calculate number of reads/sec and writes/sec for a particular database? Are there any system stored procedures to view these values? any easy method to know these for databases and also for sql server? Thanks in advance,

select DB_NAME(database_id), [file_id],io_stall_read_ms
,num_of_reads,cast(io_stall_read_ms/(1.0+num_of_reads) as numeric(10,1)) as ‘avg_read_stall_ms’
,io_stall_write_ms,num_of_writes,cast(io_stall_write_ms/(1.0+num_of_writes) as numeric(10,1)) as ‘avg_write_stall_ms’,io_stall_read_ms + io_stall_write_ms as io_stalls,num_of_reads + num_of_writes as total_io,cast((io_stall_read_ms+io_stall_write_ms)/(1.0+num_of_reads + num_of_writes) as numeric(10,1)) as ‘avg_io_stall_ms’from sys.dm_io_virtual_file_stats(null,null)order by avg_io_stall_ms desc
