Home -> Community -> Mailing Lists -> Oracle-L -> Re:RE: Disk is cheap?
For about 10 years in Unix environments, I've been using the ballpark math of $1.00 per megabyte of data for TCO (Total Cost of Ownership) and it has served me very well. Disk drives have gotten bigger and cheaper per say, but we continue to advance the overall technology in ways that keep the $1.00 math alive. First we just had disks, then we added raid, then we added fiber, then we added clustering, then we added cache to the disk controllers, then we added BCV's on EMC (Business Continuance Volumes), and then we added stand-by Oracle databases. Where will technology take us from here, I won't even take a SWAG at it, but I know my $1.00 will be going with me.

Please respond
to ORACLE-L
We say that disk is cheap, but that is a relative term. Yes an individual
drive
may be inexpensive, but if your using anykind or raid or mirroring (as we
are)
then each GB of space is twice as expensive as the individual part because
you
need two drives. Also, don't forget the cost of backing up that drive and
keeping several copies thereof.

I beg to differ.
Each disk cost the disk price + 1/24 of the infrastructure costs.
