For those using Microsoft’s exFAT file-system under Linux for the likes of flash drives and SD cards, a new patch series posted today aims to enhance the read performance. The new patches are shown to improve performance by about 10% while also having lower overhead.

Chi Zhiling with the Chinese Linux distribution Kylin OS posted the patch series today for adding multi-cluster mapping support to Linux’s exFAT file-system kernel driver. This multi-cluster mapping allows for faster read performance, especially for sequential reads when using small cluster sizes.
