<p>
The type of drive cache used by <code>PERSISTENT_1</code> file systems that are provisioned with HDD storage
devices. This parameter is required when <code>StorageType</code> is HDD. When set to <code>READ</code> the file
system has an SSD storage cache that is sized to 20% of the file system's storage capacity. This improves the
performance for frequently accessed files by caching up to 20% of the total storage capacity.
