"The price of SSD continues to fall — although it is still an order of magnitude or two above that of the hard drive. But vendors seem to get it now, and they appear to understand how to present the concept so it sells itself.

"Lou Przystas, a senior advisory consultant at the corporate executive briefing center of EMC in Hopkinton, Mass. served up a good example of how vendors WILL entice everyone to jump aboard the SSD bandwagon very shortly.

"He laid out an example within an array to highlight how SSD will initially replace Fibre Channel (FC) disks initially — at least to some degree. And helped somewhat by SATA, too.

"The original 55 TB configuration of the array consisted of 244 FC disks, each of 300 GB (FC) disks and running at 15k rpm. By reducing the number of FC disks to 136, adding 32 x 1 TB SATA disks along with 8 SSDs (each of 73 GB), you arrive at the same 55 TB capacity. On top of that, however, you get a whole lot more lot more performance, lower power consumption and reduced cost."
