The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method of increasing operational life time of SSD RAID and a storage equipment using same, the method including: configuring a data storage device to have a plurality of storage areas, each storage area including a plurality of stripes, and each stripe including an individual block of a plurality of solid state disks, where at least one block in each stripe is a check bit block, the other blocks are data blocks, and configuring two neighboring stripes in each storage area to form a composite stripe according to a plurality of index combinations in a mapping table, where the composite stripe includes two neighboring blocks in each solid state disk, and the composite stripe is divided into a stripe writing area and an empty stripe area, so that each solid state disk in each storage area has a reserved space.”

The patent application was filed on June 9, 2020 (16/896,851).

Managing backup data
Qnap Systems, Inc., New Taipei, Taiwan, has been assigned a patent (11,269,739) developed by Hsu, Chin-Hsing, New Taipei, Taiwan, for “method and system for managing backup data.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for managing backup data units stored in a data server is provided. The backup data may include a first backup data unit established by copying a source data unit into the data server in response to a data backup command received at a first time point. The method includes: acquiring a specified storage space in response to a data backup command received at a second time point, copying the first backup data unit to the specified storage space in a lightweight copy manner, writing differential data contents between the source data unit presented at the second time point and the source data unit presented at the first time point into the lightweight-copied first backup data unit in the specified storage space, and defining the resulting data stored in the specified storage space as a second backup data unit, wherein the second time point is later than the first time point.”

The patent application was filed on September 4, 2020 (17/012,094).

Data prefetch method in dynamically adjustable amount
Qnap Systems, Inc., New Taipei, Taiwan, has been assigned a patent (11,249,650) developed by Su, Jing-Wei, and Cheng, Chin-Tsung, New Taipei, Taiwan, for a “data prefetch method in dynamically adjustable amount.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method of prefetching data in a dynamically adjustable amount is executed by: determining a specified number of data blocks according to an averaged data transmission rate and a predetermined fetching index, sending out a data request command to obtain a requested data, wherein the requested data is included in a specified data and consists of the same number of data blocks as the specified number, and receiving and storing the requested data as a prefetch data consisting of the same number of data blocks for prefetch as the specified number. when the specified number is equal to or greater than two, one of the data blocks for prefetch is designated as a launch block for prefetch, and when the launch block for prefetch is read, the fetching index is optionally adjusted according to a predetermined rule.”

The patent application was filed on January 20, 2021 (17/152,826).
