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|
|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.
