Feature Comparison between Ext4 and Btrfs
We will compare the file systems based on the given features:
- Type: It could be Journaling or Copy-on-Write.
- Deduplication: A method with which a file system can remove duplicate copies of some data so as to be storage efficient.
- File-System Compression: The method with which the data automatically gets compressed when it is written in the file system.
- Checksum: Ensures Data Integrity and avoid corruption of user’s data.
- Snapshot: It is a sub-volume that shares all data along with the information related to the specific data(metadata) with another sub-volume.
- Storage Efficiency: With the help of Block Suballocation and tail-packing methods a large file is stored in blocks and in the tail space in the last block it stores some part of another file block. It also helps in increasing the system’s performance.
- Maximum Number of Files: Number of Files we can store in respective filesystems.
- Maximum File Size and Partition size: Maximum Size of File and Partition we can create in the respective filesystems,
Difference Between Ext4 VS Btrfs Filesystems in Linux
In simple terms, the filesystem is a database containing physical locations of files and data for easy retrieval at the time when it is needed. With the help of the Filesystem, the operating system controls how the data is stored and retrieved. File System usually contains files separated into groups known as directories which can hold files and furthermore directories in them. Also helps the system to store the files in the most efficient way possible.
Example:
- Ext4 and Btrfs Filesystems are pretty much well known for their performance in Linux environments.
- NTFS and FAT are known in Windows environments.
