F2FS File-System Runs Great On SDHC Storage
Phoronix: F2FS File-System Runs Great On SDHC Storage
Earlier this week I performed some F2FS file-system benchmarks on the Linux 3.8 kernel with an Intel X25 Solid-State Drive (SSD) compared to the EXT4, Btrfs, and other file-systems. Out today are benchmarks of the Flash-Friendly File-System from an SDHC card on Linux.
no random 4k published - so what for is this test on a SDHC card useful
Yes I think a random 4k test (read/write) would be quite a nice to have to. This is where I have experienced serious problems or severe performance degradation on such as USB sticks or SDHC orCF cards in the past when running filesystems like ext4.

This is excellent engineering. But hardly a surprise, conidering that F2FS has been excplicitly designed for Flash based devices, keeping in mind all the quirks.
And AFAIK, Ext4 and BTRFS are more HDD based in their design. They have to perform well in each type of storage.
Seems to be about ~50% faster on average in many cases. Not bad! Is this the final version, or do they still have more time to improve it?
he didn't test it against exfat or fat32
Yeah this is pretty incomprehensive. I can understand EXT4 against others, but the Butter? It's meant for a multitude of mass-storage devices. A low-end replacement entreprisish item and not for singular removable flash discs. FAT and Co, NTFS, EXTies all would have been far more appropriate for removable media benchmark comparison. If time permitted then, yeah sure throw in BTRFS. Does the F2FS even come close to the featurefullness and record keeping/redudancy capabilities of BTRFS in a oranges for oranges 'default' comparison?
There is no mainline exFAT support in the Linux kernel.
