Hey there,

 

I am wondering which file system would be best, in terms of speed, for booting and running OS natively from new USB 3.0 flash drive. From what I underrstand, it is 4K read speed, that is most important(unless OS is stored as one big file) for running smoothness. I don't care about compatibility, as this is purely synthetic question. Wikipedia produces whole list of flash drive specific file systems:

 

http://en.wikipedia....sh_file_systems

 

Then we got those flash drives that reach 200MB/s read times(15MB/s for 4K), which is already better than non-SSD hard drives. The question is, how fast those are with files systems designed specially for them?

JFYI, it's not *only* about filesystems, it is also about OS drivers for the given filesystem, compare:

http://www.msfn.org/...d-on-usb-stick/

 

Most probably the most "useful" filesystem would be exFAT, since it can be also used to boot with grub4dos (at least a few OS's/tools), see:

http://reboot.pro/to...ated-usb-drive/

and also:

Regarding new samsung flash drive filesystem designed for linux(kernels 3.8+), here are some benchmarks:

The whole point is - it is being still actively developed and many newer kernels bring updates.

You may tray UDF format, It is not only for optical disks,  (I started looking for it since Wonko mentioned that some where in the forum)

 

I sugest to read this: http://serverfault.c...rd-drive-as-udf

 

• Windows Vista or later: "format x: /fs:UDF" (don't use /q ! )
• Linux: "mkudffs --media-type=hd --blocksize=512 /dev/sdx"

Of curse it's good to read to the end of page, there are several tips on it. Like "Do not forget to zero the MBR first" or "it is faster than NTFS"

 

I'm going to make some tests using this format, and I'll post my findings, first will be check if Grub4dos works on it.

 

Best Regards
