19 There's no option to increase the reliability of the system. The options
20 are all there to match the file system to suit your specific data.
21 Things like number of files vs average size of files, how many inodes
22 will you need, block size, what is your reading and writing profile, do
23 you create and/or delete many files at one time, etc etc
24
25 There's not much people on this list can do to help you with this beyond
26 explaining how options work. I recommend you get out the ext4 man pages
27 and read them all from beginning to end several times. Then analyse your
28 own data needs and make a decision.
