The breakthrough in SSD promises to significantly increase their speed by overcoming one of the main limitation of NAND-memory. Currently, the data cannot be directly saved to the memory cells already used by the device. The files are saved at the available section of a drive and the outdated files are formatted. Such approach leads to the data fragmentation, decreases the SSD useful life and its efficiency.
The Japanese specialists of Chuo University announced the solution of such problem. At the IEEE International Memory Workshop in Taiping, they presented the main software controlling the data saving and storing process. It uses the scrambling addresses of logical block which prevents the data recording at the new page until it is absolutely necessary. Instead, the data are saved at the delitable block and they are consolidated in case of deleting whereby preventing the file copying and increasing the work efficiency and the reliability.
The new technologies tests showed the reduction of data recording and deleting by 55% and improved efficiency by 300%. For the current SSD with SATA III interface, it means the efficiency of 1,500 GB/sec. and electricity consumption of 60% of current electricity consumption. The most significant part of the new technology is that the improved efficiency can be used by the current users as a result of simple firmware upgrade. Another question is whether the producer want to upgrade such SSD and to hinder the sales of SSD with PCI Express interface.
