OWC Holdings, Inc., Austin, TX, has been assigned a patent (9,798,473) developed by Standing, Timothy, Mill Valley, CA, for a "storage volume device and method for increasing write speed for data streams while providing data protection."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "The present disclosure describes a method for increasing the write speed for data streams on storage volumes, such as RAID volumes, by delaying the extra operations associated with data protection when one or more data streams are written to the storage volume. Specifically, in response to a storage volume receiving a data block for writing to the volume, the storage volume determines whether the data block is part of a larger data stream. If the data block is part of a larger data stream, the data block is written to the volume, but the steps of creating volume recovery data is delaying until a period of low activity on the storage volume in order to maximize write speed for the data stream. When a low period of activity, (e.g., below a threshold level) is detected, volume recovery data is created for the data block and written to the volume.

The patent application was filed on October 29, 2015 (14/927,383).
