Hello...
Im considering moving my index-files to a RAID1. How big do these files get? What should I plan for?
Thanks, Tobias
since 1 july 2007 i store all mails to this list in 1 folder (Maildir-format)
the size of this (and the indexes) is: 31M cur 80K dovecot.index 6.8M dovecot.index.cache 44K dovecot.index.log 136K dovecot.index.log.2 4.0K dovecot-keywords 164K dovecot-uidlist 4.0K new 4.0K tmp
so, on average maybe 20%-30% of the size of your messages ?

That's actually quite a lot. Consider you run 100k+ mailboxes (1GB each) and you would move to Dovecot this will be a huge chunk out of your storage. Is using dovecot index files really that much faster than running ":INDEX=MEMORY" ? Where could I find some benchmarks about this?
Cheers,

I think a lot would depend on your average message size. Here's another data point. At my old company's server:
43,438 messages 2,350,260,769 bytes per-message ~ 54K
~3,000 folders: 486 dovecot-keywords 2675 dovecot-uidlist 2967 dovecot.index 2456 dovecot.index.cache 2967 dovecot.index.log 183 dovecot.index.log.2 251 maildirfolder 26 subscriptions
total non-message file sizes: 93,010,227 bytes / 2,350,260,769 bytes =~ 3.9 percent
And, taking into account what Timo wrote about it being client-dependent, most of the users there are using Outlook.
Best, Ben
