What is data compression?
Data compression is the process of encoding information so that fewer bits have to be stored on the drive.

Is there a performance gain with data compression?
Yes. Data compression via encoding algorithms enables a solid state drive (SSD) to write less data, which in turn yields higher write bandwidth. With a significant amount of data being compressible, performance benefits can be substantial.

Note Not all data is compressible, and data compression technology is not always used in an SSD. See the product specification for your Intel® Solid State Drive to get more details about data compression and performance.

What are some benefits of data compression besides performance?
Data compression reduces write amplification, which can increase the endurance of an SSD.

What are examples of compressible and incompressible data?

  • Compressible data: user applications, operating systems, computer utilities, and some computer games.
  • Incompressible data: encrypted files, movies, music, pictures, and zipped or compressed files.
