## Remarks

A DirectStorage queue holds entries until the title calls
[Submit](/reference/system/dstorage/interfaces/IDStorageQueueX/methods/idstoragequeuex_submit) 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.

For more information, see the "IDStorageQueueX" section in [DirectStorage
overview](/build/console-features/storage/directstorage/directstorage-overview).
