SanDisk claims new SSDs will raise speed, endurance

ExtremeFFS will improve two weaknesses in solid-state drives, company says

SanDisk on Wednesday announced a new flash memory management system called ExtremeFFS that it says will dramatically improve two of the main weaknesses today in the emerging technology of solid-state drives (SSDs).

ExtremeFFS should boost the speed of writing common types of data to SSDs by as much as 100 times, said Don Barnetson, senior director of marketing for the Milpitas, Calif., memory maker's SSD business unit. ExtremeFFS also allows data to be written to disk without erasing and rewriting nearby stored data, Barnetson said. That, along with the ability to move data around to ensure that the physical memory blocks wear out evenly, should boost the longevity of SanDisk SSDs introduced next year, he said.

The first generation of SSDs garnered praise for using less power and generating less heat. But despite claims that SSDs were faster than mechanical spinning hard drives, many customers found SSDs performed slower than conventional disks, especially when writing data.

Barnetson agreed. While SSDs are fast at writing large files and at reading either large or small files, they tend to be far slower than mechanical hard drives at storing small slices of data, what Barnetson called "random writes."

As a result, SSDs that were introduced in notebook computers last year performed at a speed equivalent to a conventional hard drive spinning at 1,000 revolutions per minute (RPM), Barnetson said. The slowest notebook drives today spin at 5,400 RPM.

A push for standards

To help overcome lingering customer concern over SSD performance and endurance, SanDisk also proposed the industry adopt two easy-to-understand metrics.

One, called Longterm Data Endurance, or LDE, would measure the total amount of data that can be written to an SSD before it fails.

For instance, a drive with an LDE of 40 TBW (terabytes written) should be able to last almost 11 years if the user writes an average of 10GB per day.

LDE would be an average figure, similar to a car's mile per gallon (MPG) rating, or the number of miles a set of tires are expected to last, Barnetson said. Vendors are free to tout a lower-range LDE for warranty or guarantee purposes, he added.

SanDisk has already submitted a proposal to JEDEC, which develops standards for the SSD industry.
