Volume Configuration Examples

Users often purchase NAS devices to store a combination of documents, media, and backups.

The following table compares the advantages and disadvantages of creating one large volume or multiple smaller volumes.

Requirement

User Goal

Single Volume

Multiple Volumes

Simplicity

Store files

Users create one large thin volume if they want to use snapshots, or one large static volume if they do not. They then create three shared folders on the volume, for documents, movies, and backups.

Users create three separate volumes for documents, movies, and backups. Users must decide how much space to initially allocate to each volume.

Speed

Edit video and audio files

Users create one large single static volume on the NAS. The files are backed up daily to another NAS, or to an external disk.

Users create a thick volume to store the movies files. Random-write performance is sightly lower than a single static volume.

Containerizing storage space

Copy a large number of movie files to the NAS

Users copy the movie files to the movies shared folder. However, they must pay attention to how large the movies folder is. If they copy too many files, the NAS becomes full and unable save any more files.

Users copy the movie files to the movies volume. When the volume becomes full, they can increase the volume size.

Multiple snapshot schedules

Protect document files using snapshots

Users create a daily snapshot schedule for a single volume. The snapshots record all changes made to document files. However, the snapshots also record changes to movie and backup files which wastes resources and storage space.

Users create a daily snapshot schedule for the document volume only.

File system repair

Fix file system errors

QTS must scan the entire single volume, which takes a long time. The volume is not readable while the scan is in progress, making the entire NAS unusable.

QTS only needs to scan the volume that has an error. Each volume is small, so scanning is relatively quick. Users can still access files on other volumes while the scan is in progress.
