Paragraph Number

241

The performance of garbage-collection-based systems may be impacted by the availability of free storage space. Block-based storage protocols, such as SCSI and/or SATA, however, presume that every block is allocated, and that the contents of the blocks need to be preserved. As such, these blocks may not be considered to be free space. As a result, reserve space may be set aside to create free space. However, setting aside the reserve space may reduce the available capacity of the storage device, and the reserved space may not be large enough to allow the garbage-collection system to operate efficiently.
