Amazon FSx for Windows File Server, a service that provides fully managed file storage built on Windows Server, now provides 14% higher levels of I/O operations per second (IOPS) for throughput capacity levels of 4 GB/s through 12 GB/s at no additional cost, bringing the new maximum IOPS level to 400,000. The increased IOPS levels enable you to improve price-performance for IOPS-intensive workloads like SQL Server databases and optimize costs for workloads like periodic reporting jobs with IOPS requirements that vary over time.
