Torn Write Prevention (TWP) is a feature that ensures 16KiB write operations are not torn in the event of operating system crashes or power loss during write transactions. This feature is now available for customers in Amazon Web Services China Regions in Amazon Elastic Block Store (EBS), a block storage service, when attached to all EC2 Nitro-based instances.

TWP enables customers running databases such as MySQL or MariaDB on EC2 and EBS to turn off the double write operation, thereby accelerating database performance Transactions per Second (TPS) by up to 30% without compromising the resiliency of their workloads. With additional performance unlocked, customers can now support their business growth without having to over provision or scale up their clusters, saving cost.

For customers with EBS volumes attached to Nitro instances, TWP is now available in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD.
