However, I'm not too sure about your concern of BTRFS on SD cards. I run my main RPi on a Kingston Class 10 4G micro SD card (With adaptor) and have never had any issues with it - I also remember that @CurlyMo and others have not had issues with good quality sd cards. There seems to be a good reason to go for micro SD cards, as they tend to use better hardware.

Personally I wouldn't keep anything critical on a SD card that has constant I/O (Not without multiple backups - of which I keep many (Full image once a month (Or when things change) - /home bi-weekly)

If you're having issues with your SD card - Get a Kingston 8G USB3 USB Drive from Amazon for about £5 and use the xbian-config to clone to it. Job done. No more I/O on SD card after booting.

The "Ideal" solution would be a SD card to USB adapter where you plug the adapter into the RPi and then plug your drive into that.

ext4, btrfs, F2Fs which is better? Who knows. Is an Audi better than a VW or a BMW?

Out of curiosity, what makes you think F2FS is any better than BTRFS?

No mate you miss my point here... i only want to extend a little more the "life" of the SDcards i use since i have Pi's running 24/7 (no point in shutting them down since they only consume 15W each with my current power converters/PSU).

Of course i make backups... that is not my concern here.

I don't know much about F2FS but i know how limited is the write cycles on a flash based memory (NAND, NOR makes little difference), and for what i've read about f2fs its designed to limit the "stress" on the same addresses over and over... (now i might be wrong... i dont know if i got that right).

If f2fs actually reduces continued stress on the same addresses (i mean memory map addresses of course) it would in theory give a little more time to live to my current setups... i use 8 GB Sandisk SDcards and i dont store anything else besides Xbian and its components, so if the OS continues to write and delete (that is a write cycle on flash mem) on the same addresses over and over without using the rest of the space, it will "kill" the transitional gate faster on that part of the flash... or so i think... i might be wrong... i really dont know how the FS deals with the write cycles and when that sector/address fails if it reallocates to another address like on a magnetic storage device.

dont know if i'm explaining myself correctly.

thks.
