1. Difference between General Purposed IOPS and Provisional IOPS in performance

    1. In Snapshot to Volume,

         General Purpose IOPS  Min size = 1GB  to Max 16384GB

         Provisional IOPS  Min size = 4GB  to Max 16384GB    ( increased performance)

 

2. Difference Between

General Purpose (SSD)
Provisioned IOPS (SSD)
Magnetic      

 

	General Purpose (SSD)	Provisioned IOPS (SSD	Magnetic
Use cases	Small to medium sized databases	Large database workloads, such as: MongoDB Microsoft SQL Server MySQL PostgreSQL	Scenarios where the lowest storage cost is important
Volume size	1 GB - 16 TiB	4 GiB - 16 TiB	1 GiB - 1 TiB
Maximum throughput	160 MB/s	320 MiB/s	40-90 MiB/s
IOPS	up to 10,000 IOPS	up to 20,000 IOPS maximum	Averages 100 IOPS
