Thank you, Everyone!
N40L with 1.02b (from the topic) worked great.
Encrypted folder speed is 50mb/s, looks like this encryption algo sucks a lot, what can we do? Plain 2xhdd raid0 gives 200mb/s
How to make it write at 100mb/s the encrypted folder?
How to mount fresh ext4 drive?

[ 6346.064135] EXT3-fs (sda1): error: couldn't mount because of unsupported optional features (2c0)
What is the right way to upgrade from 1.01?
