Why Flash Storage Is Reaching the Tipping Point Against HDDs

By Chris Preimesberger

South Korea-based giant Samsung is ahead of the pack in terms of the development of 3D NAND flash memory. The IT device giant has cranked up mass production of 3D NAND flash for both consumer electronics (mostly for netbooks and the hot-selling Android smartphones) and enterprise applications such as embedded NAND storage and SSDs.

Reportedly, Samsung also is ready to turn on (sometime in 2014) a new 12-inch fab plant in Xian, northwestern China, which then will perform much of the 3D NAND production.
Toshiba recently started construction on a new fab plant at its Yokkaichi operations in Japan, with the go date expected in summer 2014. This factory will produce 3D NAND memory, as well as chips based on more advanced node technologies. Toshiba, which is currently sampling 3D NAND flash among its best customers, is expected to reach mass production of 3D NAND flash in 2015, according to industry sources.

Micron the U.S.-based NAND Flash Leader
U.S.-based Micron recently said that the company would start handing out 3D NAND flash samples to customers in the first quarter of next year.

So why has the enterprise market experienced such a change in a relatively short span of time of five years, since SSD options started ramping up in enterprise storage? Simple: The performance and financial numbers are turning the way of solid state.

Back in 2008 and 2009, when the world’s macroeconomy was depressed, enterprises were hesitant to invest in more expensive flash arrays if their HDDs were working well enough. Those HDDs are still working well enough, but now, in many use cases, that 2008-09 “well enough” isn’t good enough for current big-data production use cases that require faster analysis and reporting. Plus, budgets are coming back, and enterprise money execs and boards of directors are realizing that IT must be refreshed in order for businesses to stay competitive.

It also turns out that non-volatile, non-mechanical memory based on NAND flash media has matured to the point where the disks are lasting as long, if not longer, than HDDs, which average less than three years in continuous use. Some flash storage makers are now offering five-year garantees on their disks.

Main Problem, Load-Balancing, Is All But Solved

Having no mechanical movement, thus no mechanical breakdowns, the main difficulty NAND flash storage faced historically was load-balancing, and that problem has all but been solved by new software that utilizes the flash surface to its maximum potential. 

"NAND flash has truly permeated our lives; this technology has been a game changer, making the world a different place and making many of the products we use today possible," said Scott Nelson, vice president of the Memory Business Unit at Toshiba America Electronic Components.

"The cost/performance of NAND flash continues to stand the test of time."
