[Galaxy S 4 i9505 Original Android Development] broodplank1337:
Thanks, indeed its very stable I find! and yes thats what I think as well. thats why the PreFinal stage is now going on, the next official release will be 100% stable.

You're welcome, and btw it's just me who makes this rom ;)

broodROM team is there though

If anyone wants to do a speedtest (for write test on all partitions) on device use this script:

#!/system/bin/sh
mount -o remount rw /
mount -o remount rw /data
mount -o remount rw /system
mount -o remount rw /cache

echo "performing write test in /data"
busybox dd if=/dev/zero of=/data/testfile0 bs=1M count=100
rm /data/testfile0
echo
echo "performing write test in /sdcard"
busybox dd if=/dev/zero of=/sdcard/testfile0 bs=1M count=100
rm /sdcard/testfile0
echo
echo "performing write test in /system"
busybox dd if=/dev/zero of=/system/testfile0 bs=1M count=100
rm /system/testfile0
echo
echo "performing write test in /cache"
busybox dd if=/dev/zero of=/cache/testfile0 bs=1M count=100
rm /cache/testfile0
echo
echo "performing write test in root"
busybox dd if=/dev/zero of=/testfile0 bs=1M count=100
rm /testfile0

place in /system or so, give chmod 755.

my result:

only mmcblk0p29 is f2fs (/sdcard)
