That's at $20K per TB and quad PIII-1GHz are faster than quad SPARCs, for
the money.

Do you have 5M users?

Let's take your user figures and the RAIDZONE prices;

50TB x $20K = $1M
$1M / 5M = $0.20 (20 cents per user, or 2 cents per MB)

If you can't make "keystone" then that's a clear indication that your market
will not support the service.

Many of those "free" email boxen are underwritten by advertising revenue. In
case you hadn't noticed, that market is collapsing. Others are bundeling
that service with other services. Incremental cost factors still contribute
to COGs and COGs should be no mkore than 60% of retail price, or you
shouldn't be offering the service. No wonder many ISPs are going under.
