Ext 2 Vs Ext 3

lyf sci

Hi Experts,

The ext 3 is disabled in the kernel compilation and tried to boot the default SDK 6 in the AM335x EVM but the kernel doesn't boot up.

How to decide which file system will better for my application ? Like among Ext2/3/4 ?

What is the standard metrics I could use to differentiate the performance ?

Hi Lyf,

You can do google for that as per your requirement.

If you are using flash based memory like NAND, NOR flash etc.,

Then you can use "ubifs" filesystem.

If it is eMMC or MMC then you can use "ext3" or "ext4"

Hi Lyf sci,

Good question.

Which filesystem is better, EXT2 or EXT3

EXT2 wins on performance and EXT3 wins on reliability. EXT3 uses journaling and is more power failure safe. But EXT4 has proved to be better than EXT3 in all ways. Refer Linux EXT FAQ from kernel.org. Wikipedia also has a good article on Filesystem Comparison

And also, you will find some performance benchmarks of different filesystem versus the storage devices in TI WIKI pages. One is here: http://processors.wiki.ti.com/index.php/Managed_NAND

Regards,

Shankari
