That's a little harsh! Even the MMC on the original 70GB SSDs wasn't 
even close to that. It was high for sure but nobody would even purchase 
maintenance if you had to repurchase theme every month!

Also to Franz' immediately prior reply at least in the U.S. (I do 
realize that things are often different by country) that the actual 
price paid for the drive is generally about 1/2 of the list price. Why 
do they price it that way? I do not understand but they do.

Another consideration with SAN storage is that you pay software charges 
per drawer in many cases. So you acquire a drawer that holds 24 drives 
and you can choose to fill that with SSDs of various sizes or with 
Spinny drives. The biggest fast spinny was only 900GB so that limited 
capacity in the drawer to about 12GB as I recall. Go beyond that and you 
needed not only to purchase an expansion drawer (not so expensive) but 
software for it AND SWMA for that software! So that 25th drive was Very 
expensive indeed!! So you reconsider those SSD prices again because they 
since they can be so very much larger you can put them all in the same 
drawer. And SSD prices tend to be quite linear with capacity. We've seen 
a four drawer spinny option fit all into one drawer easily with SSDs and 
was cheaper to acquire as well as cheaper to maintain. The additional 
plus is only 2U space and about 1/3 the total power draw (and thus heat 
generation) as well.

Bottom line is you can't look only at the price of the drive itself you 
MUST look at the total package!
