sharing and expecting to learn :)
I am wondering about the partitioning of my new external memory card manufactured by Samsung Electronics.
The very same manufacturer initially develop F2FS, the Flash Friendly File System for the Linux Kernel.
F2FS was expected to be the fastest F.S. for solid-state disks, eMMCs, and SD cards.
Initial tests confirmed it. Nevertheless posterior tests reveal that ext4 beats F2FS (...).
My guessing is that not enough research/test have been done in the matter.
Im going to set the following layout in order to test the speed for each partition:
1._ 34,7G EXT4 -> pictures, movies, backups, etc... AND/OR moved: APPs by hard/sym links; DATA by folder mount
2._ 65,0G FAT32 -> pictures, movies, backups, etc...
3._ 19,5G F2FS -> moved APPs by hard/sym links; moved DATA by folder mount
Depending on the results (specific for my phone and configuration) included in the reports from Antutu, A1SDBenmarch (possibly others too), I will most likely either:
1._ format whole microSD as F2FS -> roms,apps,data,pics,movies,etc; access using the phone (adb, usb, wifi)
2._ format whole microSD as EXT4 -> roms,apps,data,pics,movies,etc; access using any type of linux and many others
3._ format 32G as F2FS -> apps; format 64G as EXT4 -> roms,data,backups,movies; format 32G as FAT32 (any file smaller than 4G I want to be directly accessed from any device through any card reader using any OS)*
* I won't use fat32 as ext4 read/writes speeds are bit faster and i dont need to access the sd using any device
My goal is to format the external microSD card as F2FS and internal storage. F2FS is not only supposed to be better in performance but also it is supposed to expand it's lifespam
Note: Regarding partitioning the microSD in the computer, only linux will allow resizing F2FS filesystems; windows software doesnt recognize it yet, therefore it treats the partition as unformatted, neveertheless it's possible to move it.
Note2: there are programs that allow the user to mount linux partitions and read/write data on them.
Phone: Samsung Galaxy Note 3 SM-N9005, rooted, resurrection remix 5.6 (current,next5.8)
Card: Samsung EVO Plus 128Gb microSDXC UHS-I Class 10 U3 Card
ROM: Resurrection Remix v5.6 (Marshmallow)**
S.Soft: Apps2SDpro: Linked -hardlinks/symlinks- apps to F2FS partition on ext.SD. App data (TuneIn Radio recordings) moved -foldermount- to F2FS partition on ext.SD.
** I am currently designing the multiROM layout which will probably include the current ROM, plus Resurrection Remix v5.8 (Nougat) kali and some others
