xper Posted May 30, 2014 Share Posted May 30, 2014 When you need to store massive amounts of data, solid-state drive (SSD) are the best way to go. However, SSD drives have a fatal flaw that often means they don’t last as long as they should. Because of a fault with their NAND chips, they can’t overwrite data efficiently. Current SSD technology works like this: files are saved to a clean part of the drive while the other part is formatted.This means that the drive eventually becomes fragmented, which leads to lower performance over time, as well as limiting the drive’s lifespan, especially with the consideration that SSD’s can only do a limited number of writes. However, a team from Japan’s Chuo University have fixed these issues and have created technology that allows for overwriting without all the hassle, making SSD drives a lot faster, a lot more efficient, and even longer lasting.The Japanese team used a “logical block address scrambler.” This basically keeps data from being written on the clean part of the drive, unless something specifically requires it. Instead, the data is put on a block that is erased and combined in its next sweep. There's less file copying going on in the background, which means that the drive runs a lot faster.It also means that because less is going on within the drive, you don’t need as much power to make the drive run. Finally, because the drive doesn’t become as fragmented, it experiences a longer life cycle.The tests of this new technology showed remarkable results: because the drive was writing data 55 percent less than in standard drives, the drive saw a speed increase of up to 300 percent. So instead of having a device that can reach a transfer speed of a measly 500MB/s, you now have a device that can transfer data at a lightning 1.5GB/s.The craziest bit, though, isn’t the speed. You don’t even have to go out and buy a new SSD drive to get these crazy transfer speeds. The technology is completely software-based, which means all you’ll have to do is download new firmware for your drive when it’s made available. How’s that for a win-win situation?Source: Dvice Link to comment Share on other sites More sharing options...
jaclaz Posted May 30, 2014 Share Posted May 30, 2014 Well, good news but being a picky guy I cannot but underline how the given link:http://www.dvice.com/2014-5-26/your-existing-ssd-can-be-made-300-faster-and-60-more-efficient?The tests of this new technology showed remarkable results: because the drive was writing data 55 percent less than in standard drives, the drive saw a speed increase of up to 300 percent.

How’s that for a win-win situation? is "via" Neowin:http://www.neowin.net/news/ssd-breakthrough-means-300-speed-boost-60-less-power-usage-even-on-old-drivesIn tests, drives using the technology wrote data 55% less often than drives without and performance increases of up to 300% were noted. This could enable high-end devices to easily reach transfer speeds of 1.5GB/s as current models achieve around 500MB/s typically; 60% less power was also used in the lab tests due to the lack of additional drive writes.which was "via" pocket-lint:http://www.pocket-lint.com/news/129023-ssd-breakthrough-makes-drives-300-per-cent-faster-and-60-per-cent-more-power-efficientwhich finally links to the actual source Techon:http://techon.nikkeibp.co.jp/english/NEWS_EN/20140522/353388/ 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.And the actual graph of the simulation:http://techon.nikkeibp.co.jp/english/NEWS_EN/20140522/353388/?SS=imgview_e&FD=48575398&ad_q Seems like telling a different story. See also here:http://www.synergymx.com/post/2014/05/27/4x-ssd-speed-jump-not-so-fast/ IF (and when) the actual paper "NAND Flash Aware Data Management System for High-Speed SSDs by Garbage Collection Overhead Suppression." will be available, we might be able to see how much is reality and how much is hype.And IF (and WHEN) some SSD manufacturer will actually have it working, we will be able to see how it performs. jaclaz Link to comment Share on other sites More sharing options...
Guest Posted May 30, 2014 Share Posted May 30, 2014 (edited) And I thought I was the only one who actually reads the source articles of the source articles of the source articles. After so many rewrites the end result is more like rumor than fact. Nevermind that a "300% increase" does not mean "300% as fast as..." Neowin's writer doesn't do the math well, and that error was repeated in all further articles based upon it. Edited May 30, 2014 by 5eraph Link to comment Share on other sites More sharing options...
