…The new tiered flash technology, first unveiled in June at the Dell Enterprise Forum, combines high-speed SLC flash memory with slower but cheaper MLC flash memory, said Bob Fine, director of product marketing for Dell storage.

Dell then applies its Data Progression auto-tiering software to automatically tier data between the SLC and MLC flash memory and to hard drives, Fine said.

“When data comes at it, it is steered to SLC for the best performance in writes,” he said. “The data is then moved to MLC flash, as the read performance of MLC is on par with SLC. It’s unique. No one else has it.”

He gave the example of an all-flash Compellent array with six SLC SSDs and six MLC SSDs providing 12-TB capacity at a cost of about $180,000. To get 12 TB of high-performance disk storage, a company would have to purchase 82 146-GB 15,000-rpm hard drives for a total cost of $229,000.
