JP Research Team develops SSD middlewear that improves speeds by 300%

During May 18-21st at the 2014 IEEE International Memory Workshop in Taipei, Taiwan, a research team from Japan led by Professor Ken Takeuchi from Uochi University unveiled a middleware technology for SSDs that improves the NAND flash memory write performance, reduces power consumption and the overall lifespan of devices.

 

 

Current NAND writing process:

With NAND flash memory, it is not possible to overwrite data on the same memory area, making it necessary to write data on a different area and, then, invalidate the old area. As a result, data is fragmented, increasing invalid area and decreasing storage capacity. Therefore, NAND flash memories carry out "garbage collection," which rearranges fragmented data in a continuous way and erases blocks of invalid area. This process takes 100ms or longer, drastically decreasing the writing speed of SSD.

And the change:

 

..

Specifically, instead of writing data on a new blank page, data is written on a fragmented page located in the block to be erased next. As a result, the ratio of invalid pages in the block to be erased increases, reducing the number of valid pages that need to be copied to another area at the time of garbage collection.

In a simulation, the research team confirmed that the new technology improves the writing speed of SSD by up to 300% and reduces power consumption by up to 60% and the number of write/erase cycles by up to 55%, increasing product life. Because, with the new method, it is not necessary to make any changes to NAND flash memory, and the method is completed within the middleware, it can be applied to existing SSDs as it is.

Great so up to a 55% longer lifespan, now lets make NAND affordable and do away with mechanical drives completely.

Sweeeet.

They are already barely making any money/making it at a loss. Shhhh. It's honestly fine where it is.

*f***ing magic*

Now if we could get some of that for GPUs and CPUs.

Yeah, imagine what it would do for CAD and Simulation programs! Imagine editing a video... :-)
