Samsung Creates New File System F2Fs For Linux & Android

Posted by Soulskill on from the file-systems-are-for-files dept.

sfcrazy writes "Samsung has created a new Linux file system called F2FS. Jaegeuk Kim of Samsung writes on the Linux Kernel Mailing List: F2FS is a new file system carefully designed for the NAND flash memory-based storage devices. We chose a log structure file system approach, but we tried to adapt it to the new form of storage. Also we remedy some known issues of the very old log structured file system, such as snowball effect of wandering tree and high cleaning overhead."

    While the primary benefit will initially be for Android devices, this will be great news for solid state drives as well. Great job Samsung!

      I am not 100% clear on NAND tech, but Samsung had an announcement about a NAND based SSD last week. I believe this is related to the F2FS announcement today. http://www.anandtech.com/show/6329/samsung-releases-tlc-nand-based-840-ssd

    Commercial hardware companies contributing to open-source and the kernel, I mean.

    It’s nice to see that Linux and the open-source philosophy more and more just is generally accepted.

    Let's hope it.s because they have seen the advantages of humans working together, helping each other out... and not just for nefarious dog-eat-dog (aka capitalist aka "free market" aka law of the jungle*) purposes.

    * Don’t worry. I know they're not supposed to be the same. The point I want to make, is that nowadays it gets all used to describe the same thing.

    Some freezers too. They are actually involved with the development of the ELF end the enlightenment windows manager.

    I think Samsung likes Linux a lot

    Because it's legally required to trickle down perhaps?

    Considering that a Platinum membership in the Linux Foundation requires plopping down at least half a million bucks, I suspect you're probably right. :)

    Heck, Google only has a Gold membership, and we know they like Linux. Samsung is in elite territory with corporations like IBM and Intel.

    I know you're kidding, but I should point out that Linux is not a requirement for building bad interfaces (though one might claim that it helps). TV engineers in general seem to have some impressive skills at building bad interfaces. My last three TVs all had terrible interfaces, and none of them were Linux-based. :)
