The Wait Is Over in SSD Power-On Scenario

The allure of solid state disk (SSD) technology is getting a big boost thanks to new technology that promises to eliminate the wait time involved in accessing data following a shutdown or power loss.

Texas Memory System’s (TMS) Instant-On Input-Output (IO²) lets enterprises gain instant access to data from RAM-based SSDs once a unit is powered on. Prior to the innovation it could take up to two hours to access a half-terabyte of data from SSD memory.

“The downtime has always been a concern, whether it was part of a maintenance effort or a power outage,” Jamon Bowen, sales engineers, told Another benefit is that the technology enables much higher capacity to RAM that right now is typically held down in scope due to access time issues.

“The wait time has always been holding us back from increasing the capacity and now we’re looking at building new bigger systems,” said Bowen.

TMS has been manufacturing SSDs since the late 1970s and began developing flash-based SSDs just about a year ago. At this point it has no plans to license the technology but Bowen didn’t dismiss the option either.

SSDs are used to accelerate enterprise applications that handle very high transactions volumes as well as increasing concurrent users without having to add servers, RAID or conduct database tuning.

Last July, an IDC report predicted
that the technology’s performance and mobility-related requirements will push SSD revenues from $373 million in 2006 to $5.4 billion by 2011.

RAM- and flash-based SSD are gaining prominence though high costs when compared to magnetic media have limited enterprise adoption. Solutions based on RAM are typically much more pricey than flash offerings, however, with prices at about $700 per gigabyte compared to a $150 range.

“Solid state disks are becoming more important in the data center as users demand faster application performance,” Mike Karp, senior analyst at Enterprise Management Associates, stated in a release.

“As these systems achieve faster time to performance as well as greater capacity, the ROI calculation begins to shift much more favorably in favor of using SSDs with critical applications,” Karp added.
