Discover How To Improve The Performance of SSDs to 300%
- October 23, 2014
A team of researchers from Japan Chuo University has made an important discovery, through it would be possible to improve the performance of the SSDs up to 300%, further reducing consumption by 60%.
Sounds good, right? So it is best that this milestone is that, its implementation would occur through a firmware upgrade, allowing even relatively old SSDs can get to benefit from this discovery. That said I do not expect more, sure you are dying to know how this improvement can be done as more as possible, so I offer an explanation as simple as possible.
Today SSDs cannot directly overwrite data in a memory area, which means that the new data should be written in a different area until the previous is completely invalidated, that is eliminated. This topic TRIM plays an important role within the SSD, as it tells the operating system data blocks that are no longer used and can be deleted, but does not prevent performance degradation that will be produced gradually with the simple use of SSD. Yes, you have right, occurs a kind of fragmentation, which is negative not only for the performance of the SSD, but can also reduce the life. Well, with these remarks in mind we can better understand the discovery.
The key is a middleware (software that helps an application to interact with other applications) as amended which controls the way in which you write and store data on the drive, using what is known as “logical block address scrambler”. This “logical block address encoder” prevents data from being written to a new area, enabling a kind of overwriting and placing the data in a block can be erased in the next step. The above means fewer pages data on the disk and reduces the cycles of write-erase up to 55%, increasing the lifespan of the SSD. But this is not the only benefit, as well a performance boost of up to 300% and a reduction would be achieved consumption of 60%. If we consider an SSD with a speed of 500 MB / s would be talking about an impressive increase, and we would go up to 1.5 GB / s and, as anticipated, all thanks to a simple update.
