065 EBS Volume Types
6 Types
- gp2/gp3
- io1/io2
- stl
- scl
General Purpose SSD
- Cost effective
- low-latency
gp2
- previous version
- size of the volume and OPS are linked
gp3
- new version
- can increase IOPS and throughput independently
- 3000~16000 IOPS
- 125~1000 MiB/s
Provisioned IOPS (PIOPS) SSD
- Critical business apps
- Great for DB
io1 (~16TiB)
- can increase PIOPS independently from storage size
- Max PIOPS: 64,000 for Nitro EC2, 32,000 for other
io2 Block Express (~64TiB)
- sub-millisecond latency
- Max PIOPS: 256,000
Supports EBS Multi-attach
Hard Disk Drives (HDD)
- cannot be a boot volume
- ~16TiB
st1 Throughput optimized HDD
- big data, data warehouse, log processing
- Max throughput 500 MiB/s
- Max 500 IOPS
sc1 Cold HDD
- for data that is infrequently accessed
- when lowest cost is important
- Max throughput 250 MiB/s
