## Remarks

A DirectStorage queue holds entries until the title calls
[Submit](https://docs.xbox.com/reference/system/dstorage/interfaces/IDStorageQueueX/methods/idstoragequeuex_submit.md) on the queue, or one of the Enqueue methods
fills more than half of the queue's capacity since last submission and triggers
an automatic submission. All entries in a DirectStorage queue complete in the
order they are enqueued.
