Formatting a SD card : demystifying !


Is this something achievable by the Linux tools ?

Yes, but I think this is only relevant for FAT filesystems. Although I would be interested in a benchmark if this really does make a difference. Here is a description how to align a FAT filesystem:

I found several mentions of using stride and stripe-width to do a similar thing for ext3/4 filesystems. I ran benchmarks for a lot of different combinations of those for more than 30 hours and did not find any performance benefits (on a card that was clearly showing degraded performance when the partition was misaligned).
