Right, *consumer grade* SSD prices were coming down thzat much. But I am 
sure the appliance Jatin is building up (while he uses the @cisco.com 
mail domain) is intended for enterprise usage and has to have enterprise 
grade hardware components. Just like he used an enterprise grade HDD 
(though a SATA and not a SAS model with only 7.2krpm which is, as John 
pointed out, not a good choice for a virtualization host) to build the 
machine.

Investigate about SSDs made to be used in servers, SLC and not MLC type 
of chips, SAS interface. Then lets speak again after you have checked 
their prices.
