EC2 Volume Types
In this, we will learn about EC2 Volume Types.
A robust, block-level storage device that you may attach to your instances is an Amazon EBS volume. You may utilise a volume as if it were a physical hard disc after attaching it to an instance. EBS volumes can be changed at any time. On live production volumes, you may dynamically increase volume size, alter provided IOPS capacity, and change volume type for current-generation volumes attached to current-generation instance types. Amazon EBS volumes
- is a block-level storage device
- can attach to a single EC2 instance
EBS volume types, differ in performance characteristics and price, and are briefed below
- SSD storage is optimized for transactional workloads for high IOPS. 2 SSD volume options
- EBS Provisioned IOPS SSD (io1) – For latency-sensitive workloads, requiring minimum-guaranteed IOPS. Pay separately for provisioned IOPS
- EBS General Purpose SSD (gp2) –For general use. Balance between cost and performance.
- HDD storage for throughput-intensive workloads. 2 types
- Throughput Optimized HDD (st1) –For frequently accessed, throughput-intensive workloads.
- Cold HDD (sc1) – For less frequently accessed, throughput-intensive workloads.
| Solid-State Drives (SSD) | Hard Disk Drives (HDD) | |||
| API Name | gp2 | io1 | st1 | sc1 |
| Volume Size | 1 GiB – 16 TiB | 4 GiB – 16 TiB | 500 GiB – 16 TiB | 500 GiB – 16 TiB |
| Max. IOPS/Volumes | 16,000 | 64,000 | 500 | 250 |
| Max. Throughput/Volumes | 250 MiB/s | 1,000 MiB/s | 500 MiB/s | 250 MiB/s |
| Max. IOPS/Instance | 80,000 | 80,000 | 80,000 | 80,000 |
| Max. Throughput/Instance | 1,750 MiB/s | 1,750 MiB/s | 1,750 MiB/s | 1,750 MiB/s |
| Dominant Performance Attribute | IOPS | IOPS | MiB/s | MiB/s |
The default EBS volume type is gp2.
