"Violin looks like a much better way than Ramback to use it. The reason is that it better
answers my mistrust of the battery, hardware, and Linux. I can put multiple Violins in a RAID
array and when the battery, hardware, or Linux fails in one, I don't lose data. And it looks
roughly as fast as Ramback."
It is exactly as fast as ramback, because it is ramback. Ramback was written to provide the
Violin box with stable backing store. It is just a nice bonus that ramback happens to be
useful for ramdisks in general, and for my code hacking workstation in particular.
