For all its merits, SSDs have a limited resource on the number of read-write cycles, but still there was no universally accepted measure that would allow an objective comparison of different device models and manufacturers. Although for a single flash memory chip similar indicator definition has long mastered the producers, it can not be mechanically transferred to the SSD-drives in general, as in this case, the additional influence the specifics of the implementation of the controller unit and some other factors. SanDisk is proposed to introduce an industry standard setting “long-term stability data» (Longterm Data Endurance, LDE), allowing us to reduce the expected lifetime of an SSD to a single number.
As planned by SanDisk, LDE index will primarily be based on the total amount of terabytes, which can take on record SSD-drive during the period of its operation (Terabytes written, TBW). In addition to other information in its announcement of SanDisk has a curious figure, obtained by researchers of Bapco, a description of the activity of the “professional PC user,” followed by a record 87 GB per week.
The industry, in particular – the company Seagate, taking active part in the work of the group Jedec JC-64, supported the need to introduce some kind of uniform characteristics that can display the “endurance» SSD-drives. However, there is no certainty that as this characteristic will be adopted this LDE.
