Features

Wear-Leveling algorithm

The controller supports static/dynamic wear leveling. When the host writes data, the controller will find and use the block
with the lowest erase count among the free blocks. This is known as dynamic wear leveling. When the free blocks ‘erase
count is higher than the data blocks’, it will activate the static wear leveling, replacing the not-so-frequently-used user
blocks with the high erase count free blocks.

Bad-block management

When the flash encounters ECC fail, program fail or erase fail, the controller will mark the block as a bad block to prevent
using this block and cause data loss in the future.

Enhanced S.M.A.R.T. function

Transcend’s SSDs support the innovative S.M.A.R.T. command (Self-Monitoring, Analysis, and Reporting Technology)
that allows the users to evaluate the health information of their SSD in an efficient way.

StaticDataRefresh Technology

Normally, ECC engine corrections are taken place without affecting the host normal operations. As time passes by, the
number of error bits accumulated in the read transaction exceeds the correcting capability of the ECC engine, resulting in
corrupted data being sent to the host. To prevent this, 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 the life of the data.
