EBS Type
Type
gp2/gp3(SSD)
General purpose SSD volume that balances price and performance for
a wide variety of workloads
io1/io2(SSD)
Highest-performance SSD volume for mission-critical low-latency or
high-throughput workloads
Used case
• Critical business applications with sustained IOPS performance
• Or applications that need more than 16,000 IOPS
• Great for databases workloads (sensitive to storage perf and consistency)
io1/io2(4G-16TB)
features
• Max PIOPS: 64,000 for Nitro EC2 instances & 32,000 for other
• Can increase PIOPS independently from storage size
• io2 have more durability and more IOPS per GiB (at the same price as io1)
• io2 Block Express (4 GiB – 64 TiB):
Sub-millisecond latency
• Max PIOPS: 256,000 with an IOPS:GiB ratio of 1,000:1
st1(HDD) - Throughput optimized
Low cost HDD volume designed for frequently accessed, throughput- intensive workloads
Big data, Data Warehouse and log processing
MAx throughput 500MiB/S
Max IOPS is 500
sc1 (HDD)
Lowest cost HDD volume designed for less frequently accessed workloads
For data that is infrequently accessed • Scenarios where lowest cost is important • Max throughput 250 MiB/s – max IOPS 250
RAID 0
RAID 1
