linux kernel 5 (ubuntu 18.04)
Use case is writing 100K files (50KB) in bursts, file system half 500million of files (per folder can be a small number if needed) and deleting old files all of the time.
Writing on SDDs
Requirement is performance (especially of the write) and stability
I've read about xfs, ext4, reiserfs, btrFS and F2FS
I don't have time to benchmark all so would appreciate to thin the list with the best file systems for my use case.
For instance reiserfs is good for many small files but is 50KB small? Since it is ssd will F2FS be a real advantage in this case?
