Features

 Global Wear Leveling – Advanced algorithms to enhance wear-leveling efficiency

(1) Record the block erase count and save this in the wear-leveling table.

(2) Finds the static-block and saves this in the wear-leveling pointer.
(3) Checks the erase count when a block is pulled from the pool of spare blocks. If the erased block count is larger than

 ECC Algorithm

 Bad Block Management

 Advanced Garbage Collection

Transcend’s Garbage Collection mechanism improves SSD performance. Advanced Garbage Collection can efficiently

improve memory management to ensure stable SSD performance. Transcend’s advanced flash management can

maintain the drive’s high performance even after an extended operating time.

 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)

which allows users to evaluate the health status of their SSD efficiently.



Advanced Power Shield

The controller uses an internal intelligent power shield circuit to prevent SSD from damage in the event of a sudden

power outage. The SSD’s internal power detection mechanism can monitor power provided by host. Should a sudden

power outage occur, the SSD can execute the advanced power shield mechanism to protect data in the SSD.

 Hardware Purge and Hardware Write Protect

The SSDs have optional features such as hardware trigger for quick data erase and write protection. These features

may be enabled by simply connecting a switch to the designated pins.

Global wear leveling ensures every block has an even erase count. By ensuring all spare blocks in the SSD’s flash chips

are managed in a single pool, each block can then have an even erase count. This helps to extend the lifespan of a SSD

and to provide the best possible endurance.

There are three main processes in global wear -leveling:

the Wear Count (WEARCNT), then the static blocks are leveraged against the over-count blocks.

The controller uses a BCH 40 Bit ECC algorithm per 1024 bytes depending on the structure of the flash. BCH40 may

correct up to 40 random bit errors within 1024 data bytes. With the help of BCH40 ECC, the endurance of the

Transcend SSD is greatly improved.

When the flash encounters an ECC, program or erase failure, the controller will mark the block as a bad block to

prevent use of this block and cause data loss in the future.

 StaticDataRefresh Technology

Normally, the ECC engine corrections take place without affecting normal host operations. Over time, the number of

bit errors accumulated in the read transaction exceeds the correcting capacity of the ECC engine, which results in

corrupted data being sent to the host. To prevent this, the controller monitors the bit error levels during each read

operation; when the number of bit errors reaches the preset threshold value, the controller automatically performs a

data refresh to “restore” the correct charge levels in the cell. Implementation of StaticDataRefresh Technology

reinstates the data to its original, error-free state, and hence, lengths the data’s lifespan.
