ext3 and ext4 is much much better and faster. But it is only work only on Unix OS. lol..I guess everyone is brained washed by MS to make such terrible format standardised at the first place.
ext has its problems. Its not perfect.

Hey all I've conducting a test with my eMMC benchmark.
Got this screenshot for you all to look at.

1. eMMC

2. Adata Class 6 8G card

I use this tool.
Flash Memory Toolkit.

Benchmark may be vary on different machine. This machine of mine is very slow. eMMC seems to be faster at smaller files but slower at larger file. But very consistant Write speed.

I have created this thread from twenty-three posts that were formerly a sub-thread within "Firmware 1.3 on its way????" Please continue discussion of flash defragmenting and defragmenters here, in this thread.

Don't know how the benchmark works, but generally, for writing whole files (say a big AVI file), your eMMC should be around 3 times faster than that (about 17MB/sec)

If anything currently in use is worse than FAT, I can't think of it.

So being a Linux-only kind of chap, I went through the process of re-formatting my MicroSD as ext3 and having the N900 mount it automatically. I forget the thread but with a bit of tweaking it's possible.

Performance seemed better and it was nice being able to store symlinks & files larger than 4 GB.

But I could not find a way of solving the UID/GID permissions problems. The N900 user has one UID, my desktop has a different one, files & directories do not always have universal read/write access and I don't want to permanently change my umask on either N900 or Desktop PC. I also don't want to manually change permissions of everything I copy back & forward.

So until there is a filesystem flag to ignore ownership, I'm back to crap old FAT32 for my Linux-to-Linux transfers .

Warning: any reformatting should use a default block size for this flash device. In this case you can get a top write performance. If you use something different then performance may fall down dramatically. The right block size during flash formatting has a biggest effect on performance in comparison with VFAT/EXT3 issue.

Yeah I used default block size when I format. Just a default format windows one. Not sure if the performance may increased if a file larger than 700Mb being copy but it is depending on host machine as well. Beside that the device is pluged into a cable and is not directly from the card to the computer. I think this is why the performance dropped.

Not that I have spent a lot of time on it, but I have never got mine to mount automatically on boot.

I also got an additional 500MB free space on a "8GB" card when I dumped its contents, reformatted to ext2, and restored contents.

I use scp to transfer, but sshfs should do what you want. I haven't messed with sshfs in a long while, and never used it much, so I don't remember all the details.
