File system for SD card to be used as /
I've got an old server that is used for file server and some other stuff.
I'll replace the / disk by a SD card in order to have a more silent computer with less power consumption. Data is in another disk.
For the SD card filesystem what can be the best choice?
Ext4 with no atime? without other options?
UBIFS? What options should be best?
I just don't want the SD card to get worn out very quickly.
