Problems solved by technology

However, there may be costs or detrimental effects associated with data compression, which can result in reduced or degraded overall performance (e.g., in terms of die area consumed by compressed components, throughput, power consumption, etc.)
Therefore, there is often a trade-off between the costs or penalties associated with data compression and the benefits that compression has with respect to mitigating write amplification
Therefore, compression has been tried in SSDs, but is still not widely used in SSDs considering the higher cost and adverse effects of compression

Abstract

The present invention facilitates efficient and effective information storage device operations. In one embodiment, a method comprises: receiving a first amount of original information associated witha first set of logical storage address blocks; condensing the first amount of original information into a first amount of condensed information wherein the size of the first amount of condensed information is smaller than the first amount of original information and the difference is a first capacity saving; storing the first amount of condensed information in a first set of physical storage address blocks; tracking the first capacity saving; and using at least a portion of the first capacity saving for storage activities other than a direct bonding address coordination space for the first amount of original information.

Description

technical field [0001] The present invention relates to the field of information storage capacity adjustment management. Background technique [0002] Various electronic technologies, such as digital computers, calculators, audio devices, video equipment, and telephone systems, help to increase productivity and reduce costs in analyzing and communicating data and information in most fields of business, science, education, and entertainment. These activities often involve the transfer and storage of large amounts of information, and the complexity and cost of the networks and systems that perform these activities can be enormous. Solid state drives (SSDs) are often used to provide fixed storage space (eg, similar to how some hard disk drives (HDDs) are used) in various environments (eg, data centers, server farms, in the cloud, etc.). [0003] NAND flash SSDs generally facilitate relatively quick access to stored information, but tend to have other characteristics that may a...
