No, sorry for the confusion. My scripts simply do : $ lzop -cd file1.lzo | process | lzop -c3 > file2.lzo With decent CPU, you can reach higher read/write data rates than what a single off-the-shelf disk can achieve. For this reason, I think that reiser4 would be worth trying for this particular usage. And in this case, I'm not interested at all in reliability. It's just temporary storage. If the disk fails, I throw it away and buy a new one.
