With most applications and workloads, storage traffic is typically 70% reads. There are applications that generate all reads or all writes, but the average is a 70/30 read/write ratio. VDI is typically 70-80% writes during steady state, as demonstrated by the test results. It is important to configure the storage array to accommodate the higher write ratio.
