Disadvantages of Disk Compression
- Performance Overheads: Encoding and decoding data during writes and reads imposes additional CPU and memory loads affecting I/O performance if systems are underpowered.
- Compression Incompatibility: Inability to access compressed data across alternative OS platforms if proprietary algorithms were employed not supported elsewhere
- Encryption Inefficiencies: Already encrypted data offers minimal additional space savings when compressed due to high entropy. Combining the two increases resource loads.
- Fragmentation Inefficiencies: Heavily fragmented filesystems reduce compression effectiveness due to discontinuity in detectible redundancy patterns. Defragmentation improves results.
- Decreased Reliability: Minor corruption or lost encoded data can sometimes prevent full file recovery compared to uncompressed files which are more fault tolerant.
- Increased Complexity: Additional software and computing complexity like allocating resources, managing inconsistencies etc. increases administrative overheads.
What is Disk Compression?
Disk compression refers to the process of encoding data on disk drives in a compact form that reduces storage volume requirements. Understanding what disk compression entails and how it works can help manage rising data needs. In this article, We will understand the process of disk compression, the uses of disk compression, and more.
