Sony Contributes ~73%+ Performance Improvement For exFAT Linux Driver

[Vermilion]

Very nice, but if its going to be used on 5.19 it will not affect a lot of mobiles. Most likely they have to backport it down to...3.x? or 4.19? dont know which one is currently used for Android phones. But usually its quite old old long long stable.

Forget the improvements in 5.19, the exFAT driver itself was introduced in 5.4 so Android requires backporting or out-of-tree drivers anyway.

I never used that filesystem to be honest. What are its advantages? It's open source? It comes from Microsoft, right?

as very well pointed out by jacob it is the only filesystem able to be used adhoc by mac, win and linux without any size restriction. Perfectly for USB drives or smartcards. The imporatnce of this filesystem is quickly overseen since USB thumbdrives have reached sizes >4GB.

I'm wondering how this compares to the performance of ext4, ext3, ext2. Maybe even without journaling.

It is open source and has one HUGE advantage: like (V)FAT it offers perfect interoperability by being supported by everything and everyone. But unlike (V)FAT, it's 64 bit so it doesn't suffer from the same volume size limitations. I think (but don't take my word for it) that it also got rid of that horrible hack in VFAT that allowed long file names on top of the old 8+3 format. Instead it supports long file names natively.

It's also the only Filesystem natively supported by both Wibdo s and MacOS allowing easy transfer or use of files between them

That percentage figure is strangely inverted and not intuitive at all. I'd be saying it's four times faster!

That's good too, but I have to save it somewhere as I will not remember it.

mkfs.exfat --help

That's why commands have a --help switch.

It is compatible with windows and that's about it. It may be the least bad option out of fat32 ntfs and exfat.

Danny3: Not GUI but the mkfs.exfat command has a --cluster-size=size option to specify the size.

That's good too, but I have to save it somewhere as I will not remember it.
Thank you!
