3Mb * 14000 = 44040192000
Yep.
Also, CCR and RAID5^W, with a cluster/page inefficiencies:
3mb * 14000 * 1.2 * 2 = 105696460800 / 1Gb = 98.43.
A base 7200 FC head in 2014 cost ~$40k for 8x1.2Tb SAS 10k (PROMO, retail was $78k), so
40000/(7*1200) = $4.76/Gb (RAID5 of 8 disks)
So the cost of just storing a completely unneeded ONE E-MAIL which wasn't even read by 99% of personnel:
4.76 * 98.43 = $468.52 (at least)
NOT including tape backup costs, satellite transfer links, storage on the local machines, costs of receiving the message on handsets in roaming.
Edit: I don't remember the specs (we had 1 head with 3 JBODs?), but back when I counted I got around $2k for this. I repeat: for storing ONE e-mail.
