5. Block Diagram and Function Explanations 5.1 Block Diagram 5.2 Function Explanations 5.2.1 Global Wear Leveling Function Global wear leveling ensures that every block has an even erase count. This helps to extend the life expectancy of an SSD. There are three main processes in global wear leveling: (1) Record the block erase count and save this in the wear-leveling table. (2) Find the static-block and save this in the wear-leveling pointer.
the controller monitors the error bit levels at each read operation. When it reaches the preset threshold value, the controller automatically performs data refresh to “restore” the correct charge levels in the cell. This implementation practically restores the data to its original, error-free state, and hence lengthening data life. 5.2.
through the host. The encryption key is also stored on the device (commonly AES is utilized). (1) Features boot authentication: When the user starts the device, the shadow MBR will conduct a pre-boot identification; where the user is cleared, the normal boot process will begin and connections to the devices are to be made. (2) Sector specific permissions: The device manager may create a logical block address (LBA) range and assign different permissions for each LBA range.
6. Technology Term Explanations 6.1 TBW Terabytes Written (TBW) directly measures how much you can write cumulatively into the drive over its lifetime. Essentially, it just includes the multiplication conducted above in the measurement itself. For example, if your drive is rated for 365 TBW, that means you can write 365 TB into it before a replacement is required. If its warranty period is 5 years, that works out to 365 TB ÷ (5 years × 365 days/year) = 200 GB of writes per day.
7. Installation Requirements 7.1 SSD Installation Regarding the system assembling, the torque force of mounting screws should not exceed more than 2 Kgf-cm of torque. For SATA cable connection, the cable should not longer than 1 meter and well-connected is necessary to avoid signal transmission error. The standard 2.5 inch SATA interface has a separated connector for power connection. For the connection detail, please refer chapter 4.
