The number of I/O operations per second (IOPS) that the volume supports.
The volume size, in gibibytes (GiB). This can be a number from 1 - 1024. If the volume type is EBS-optimized, the minimum value is 10.
The throughput, in mebibyte per second (MiB/s). This optional parameter can be a number from 125 - 1000 and is valid only for gp3 volumes.
The volume type. Volume types supported are gp3, gp2, io1, st1, sc1, and standard.
