Amazon doubles data rate of EBS storage

Summary:Shifting data between servers and Elastic Block Store volumes faster should mean applications will be more responsive.

Amazon has doubled the guaranteed data rate that customers can buy for storage attached to their rented Amazon servers.

The upgrade to Amazon's Elastic Block Store (EBS) technology gives customers the ability to dial up the data ingest and egress rate of provisioned 'IOPS EBS volumes' to 2,000 input-output operations per second (IOPS) per volume.

For perspective, a 15,000 RPM hard drive is capable of around 200 input-output operations per second. The faster data transfer rate means customers can shift information between their servers and their EBS volumes faster, which means applications will be more responsive. 

"This is an order of magnitude more IOPS than you can expect from a high-end 15,000 RPM disk drive," Amazon wrote in a blog post announcing the upgrade. "If you've been RAIDing multiple volumes together for even higher performance, you may be able to achieve the desired level of performance with far fewer volumes."

The provisionable IOPS service was originally launched in August. EBS has come in for a good deal of criticism from Amazon users: Amazon's most serious recent outage began with degraded performance in a few EBS volumes stemming from a bug in an EBS software agent. Some early customers of the new technology include SAP, which uses EBS to host its in-memory HANA data platform.
