# AWS HealthOmics now supports ephemeral storage for private workflows

**[AWS](https://daily.dev/sources/aws)** · 2 min read · 0 upvotes · 0 comments

## Summary

AWS HealthOmics now supports ephemeral storage for private workflow tasks, providing dedicated scratch space mounted at /tmp. Each task gets 16 GiB by default at no extra cost, configurable up to 3,072 GiB per task via WDL, Nextflow, or CWL directives or the StartRun API. This benefits I/O-heavy bioinformatics workloads like genomic sequence alignment, BAM sorting, and variant calling by isolating scratch I/O from shared run storage. All ephemeral volumes are encrypted and automatically deleted on task termination. The feature is available across all regions where HealthOmics operates.
