Choosing a File System Block Size
Choosing a File System block size is an important decision, as it affects performance, storage
size, and efficiency of storage utilizations:
•
A 32 KB File System provides higher throughput when transferring large files. However,
4 KB File Systems will perform better than 32 KB File Systems when subjected to a large
number of smaller I/O operations.
•
If the File System contains lots of relatively small files, a 4 KB File System will be much
more efficient in terms of space utilization.
•
For instance, with a 32 KB file system block size, a 42 KB file would take up two 32 KB
blocks (2 x 32 KB = 64 KB). This wastes 22 KB of space. To avoid this scenario, eleven 4
KB file system blocks (i.e. 11 x 4 KB = 44 KB) can be used to accommodate the 42 KB
file. With a 4 KB file system block size, only 2 KB of space is unused.
•
The maximum size for a Silicon File System depends on the relationship between the file
system Block Size and Titan memory size. Blocks sizes can be either 4 KB or 32 KB, and
Titan memory sizes can be either 2 GB or 4 GB. The table shown below shows the
maximum file system size for different combinations of block and memory sizes.
