Amazon EBS General Purpose SSD (gp3) volumes balance price and performance and are recommended for most general-purpose workloads, including virtual desktops, medium-sized single-instance databases, development/test environments, and boot volumes. gp3 volumes also let you provision IOPS and throughput independently from capacity at a lower price per GB than gp2.
Provisioned IOPS SSD (io1/io2) volumes deliver consistently high performance for mission-critical, I/O-intensive databases but cost more because you pay separately for each provisioned IOPS. Cold HDD (sc1) volumes are optimized for infrequently accessed, throughput-oriented data and currently offer the lowest price per GB of all EBS volume types. Magnetic (standard) volumes are previous-generation, low-performance options suited to small datasets that are rarely accessed and are not the cheapest choice today.
