Noam is right in most of his text.

But I have to add that the following sentence should be taken with some grain of salt.
 
> If the index is on a separate drive, though - e.g. index on SSD, data on HDDs - mirrorarenas can be used to keep the arenas in sync between multiple (sets of) HDDs, so that if one fails, venti can use the working drive while continuing to use the index on the SSD.

You are better off putting the arenas on SSD, not the index, if you don't want to stress your SSD. Of course, index on SSD looks good at 1st sight for performance, but the  buckets have to be rewritten and reordered at each addition .

If you want the performance gain, and have enough main memory , you should better try my mventi (which uses standard arenas and no index file). -> see other thread
