Amazon Elastic Block Store (EBS) provides block-level storage to EC2 instances in the AWS cloud. EBS offers two types of storage volumes:
- SSD (Solid State Drive) volumes – also known as gp2, provide high-performance, low-latency disk I/O for demanding workloads such as big data processing and boot volumes.
- HDD (Hard Disk Drive) volumes – also known as st1, are optimized for large, sequential read/write workloads such as big data, data warehousing, and log processing.
Choosing between SSD and HDD will depend on the I/O and storage capacity requirements of your application.
| Feature | SSD (EBS gp2) | HDD (EBS st1) |
| Performance | High I/O and low latency | Large sequential I/O for big data |
| Volume sizes | 1 GB to 16 TB | 500 GB to 16 TB |
| Throughput | Up to 10,000 IOPS | Up to 500 IOPS |
| Latency | Low | High |
| Cost | Higher | Lower |
| Use cases | Applications with high I/O requirements, boot volumes | Large sequential data workloads, big data, data warehousing, log processing |
General Purpose SSD and Provisioned IOPS SSD are two different types of solid-state drives (SSD) used for cloud storage. General Purpose SSD is designed for general use cases with moderate I/O requirements and is cost-effective, but with burstable performance. Provisioned IOPS SSD, on the other hand, is designed for I/O-intensive applications such as databases and big data analytics and provides guaranteed I/O performance with higher cost.
| Feature | General Purpose SSD | Provisioned IOPS SSD |
| Purpose | Suitable for a broad range of use cases with moderate I/O requirements | Designed for use cases with high I/O requirements such as databases, big data analytics, and other I/O-intensive applications |
| Performance | Lower cost with burstable performance (typically 3 IOPS/GiB) | Higher cost with guaranteed I/O performance (up to 64,000 IOPS) |
| IOPS | Burstable performance up to a certain limit, with average IOPS ranging from 100-16,000 | Guaranteed IOPS performance, with IOPS ranging from 10-64,000 |
| Latency | Average latency ranging from 10-20ms | Lower latency (typically <10ms) compared to General Purpose SSDs |
| Cost | Lower cost compared to Provisioned IOPS SSDs | Higher cost compared to General Purpose SSDs |
Jaiinfoway solution provides both EBS-SSD and EBS-HDD, it gives its customers the option to choose the type of storage that best fits their needs based on their specific use case and performance requirements.
EBS-SSD (Elastic Block Store – Solid State Drive) offers high performance, low latency, and high I/O operations per second (IOPS), making it ideal for use cases such as database and big data analytics. It is also suitable for applications that require high levels of random I/O access.
On the other hand, EBS-HDD (Elastic Block Store – Hard Disk Drive) offers a lower cost per gigabyte compared to EBS-SSD and is designed for use cases that require large amounts of sequential data access, such as big data warehousing and backup and archive storage.
By offering both EBS-SSD and EBS-HDD, Jaiinfoway solution enables its customers to choose the type of storage that best fits their specific requirements and optimizes their storage costs.
