"A new form of nonvolatile MRAM memory with the promise to eventually replace DRAM is slowly making its way into products, but analysts said it could be a long time before DRAM technology is cast aside ..."
SSD rely on DRAM as the linchpin for there underlying technology. The problem is that power has to be available all the time. Now we learn of a new solution; "Could MRAM Ultimately Replace DRAM"? Quite possibly, but not in the near future as density and costs are not comparable to DRAM.

"It’s seen major new and maturing products and technologies, big-time venture capital funding, and catch-up efforts by major storage vendors shoehorning fast SSD into array architectures designed for much slower disks ..."
The pundits are again citing the up coming year as the breakout year for SSD; unfortunately that line has been used for the last 10 years. There is no doubt that the pricing for SSD is coming down but enough to justify 100% SSD shops? I have doubts that SSD will mean the
"End of High-End HDD Storage", just like HDD has never completely replaced tape.

"In the last few years we've seen advances in storage technology that have tremendous potential for IT customers. Some of these are enabled by investments made in developing flash solid-state drive (SSD) technology and adapting it to enterprise storage systems ..."
Go back to the early days of RAID and you find lots of pushback from the storage admins and upper management. "Storage Technology Adoption Is A Slow Process", the problem is that storage technology is not. These two conflicting points can cause a serious delay in adoption, especially these days in determining the value of data.

"Companies may want to skip using a tiered storage architecture and move directly to an all-SSD (solid state drive) architecture, according to a new report from Forrester Research. In the report, Forrester contends that while enterprise-class SSDs are vastly more expensive than hard disk drives, deduplication can reduce capacity requirements, making flash a cost-effective, better-performing alternative ..."
While tape is not mentioned specifically in the article the 30,000 foot view of data storage, protection and access has to include all three. The problem with "Skip Data Tiering, Go Directly to All-SSD Storage" is the assumption of two things. Prices for disk won't fall and the deduplication that is mentioned is not applicable to traditional disk and tape. Both are incorrect.
