The new High Speed Gen2 solution is based on hardware that includes SSD disks with NVMe interfaces. The performance allocation is progressive and linear (30 IOPS allocated per GB and 0.5MB/s allocated per GB) with a maximum of 20k IOPS and 1GB/s per volume. Your IOPS and bandwidth performance will increase as you scale up your storage space. With the High Speed solution, performance is fixed. You will get up to 3,000 IOPS per volume, regardless of the volume size. High Speed performance is theoretically best for volumes up to 100GB. Above 100GB per volume, you will get enhanced performance with a High Speed Gen2 volume.
