To characterize storage performance from a host perspective, we enter into a
multidimensional discussion involving considerations that include: throughput (IOPS and
MB/s); read or write; random or sequential; block size; and response time. Here are a couple
of rules that will help characterize these terms:
Throughput or bandwidth is measured in two separate and opposing metrics: Input/Output
operations per second (IOPS) and data transfer rate (MB/s). Generally, random workloads
are characterized by IOPS and sequential workloads by MB/second.
Maximum IOPS ar ...
