1.3. ATA/ATAPI-6 Standard
The Industrial 2.5” PATA (IDE) SSD disks are fully compatible with the ATA/ATAPI-6 standard.
1.4. Technology Independence - Static Wear Leveling
In order to gain the best management for flash memory, the Industrial Rugged Metal 2.5” PATA (IDE) SSD supports
Static Wear-leveling technology
to manage the Flash system. The life of flash memory is limited; the management
is to increase the life of the flash product.
A static wear-leveling algorithm evenly distributes data over an entire Flash cell array and searches for the least used
physical blocks. The identified low cycled sectors are used to write the data to those locations. If blocks are empty, the
write occurs normally. If blocks contain static data, it moves that data to a more heavily used location before it moves the
newly written data. The static wear leveling maximizes effective endurance Flash array compared to no wear leveling or
dynamic wear leveling.
