Local SSD
Google Cloud Platform’s Local SSD provides ephemeral storage designed for scratch data and caches. It delivers the lowest latency and highest performance among available options. This service is ideal for workloads requiring rapid access to temporary files or high-speed caching mechanisms without persistent data retention requirements.
Choose this solution when you need maximum IOPS for short-lived data. Be aware that there is no free tier available for this storage type. You will incur costs immediately based on a pay-as-you-go model, so monitor usage closely to avoid unexpected charges for high-performance ephemeral disks.
