# Instance Store
#cloud #aws #storage
Instance Store in AWS is fundamentally different to EBS. These stores are in the same server rack as the EC2 Servers are hosted and are high performance. These Store are Ephemeral (data are not persisted and will be lost when powered off). These store will have several differences to a normal EBS volume on the:
• Instance stores are ideal for temporary storage of information that changes frequently, such as buffers, caches, or scratch data
• Instance store volume root devices are created from AMI templates stored on S3
• Instance store volumes cannot be detached/reattached
