SSD breakthrough means 300% speed boost, 60% less power usage... even on old drives

A breakthrough has been made in SSD technology that could mean drastic performance increases due to the overcoming of one of the major issues in the memory type. Currently, data cannot be directly overwritten onto the NAND chips used in the devices. Files must be written to a clean area of the drive whilst the old area is formatted. This eventually causes fragmented data and lowers the drive's life and performance over time.

However, a Japanese team at Chuo University have finally overcome the issue that is as old as the technology itself. Officially unveiled at the 2014 IEEE International Memory Workshop in Taipei, the researchers have written a brand new middleware for the drives that controls how the data is written to and stored on the device. Their new version utilizes what they call a 'logical block address scrambler' which effectively prevents data being written to a new 'page' on the device unless it is absolutely required. Instead, it is placed in a block to be erased and consolidated in the next sweep. This means significantly less behind-the-scenes file copying that results in increased performance from idle, during intensive jobs and a longer lifetime for the drive as SSDs have a finite number of possible write operations.

Há algumas inconsistências na informação que se encontra no artigo, especialmente tendo em conta que o artigo é relativamente novo. Diz que as velocidades actuais dos SSD são de 500MB/s. Actualmente, os SSDs já vão tem taxas na ordem dos 3GB/s em leituras e mais de 2GB/s em escritas, com PCIe.

EDIT: Já agora, aumentar a performance em 300%, significa aumentar 4 vezes e não 3 vezes. Aumentar 100% = 2x mais rápido.
