Data Sheet
Features
• Global Wear Leveling – Advanced algorithm to enhance the Wear-Leveling Efficiency
Global wear leveling ensures that every block has an even erase count. This helps to extend the life expectancy
• Advanced Garbage Collection
Transcend’s SSDs have a perfect garbage collection mechanism to help improve performance. Advanced Garbage
collection can efficiently improve memory management to ensure the SSD’s stable performance. With Transcend
advanced flash management, the drive can still keep high performance even after a long operating time.
LDPC ECC
The LDPC ECC engine executes parity generation and error detection/correction features, and enhances decoding
throughput and data reliability. With LDPC of correction 1e-2 RBER, the hard and soft decoding mechanism provides
powerful error correction. Hence the controller can enhance the endurance and retention of TLC NAND and extends the
SSD lifespan.
RAID Protection
In case of uncorrectable errors occurring within a superblock (a pre-defined area which consist of a particular set of
blocks across physical NAND units), the RAID engine recovers the uncorrectable error chunk by using a certain storage
space of parity bits. Incorporated with LDPC, the RAID ensures a comprehensive level of data integrity while providing a
broad range of RAID overthead protection
Enhanced S.M.A.R.T. function
Transcend SSD supports S.M.A.R.T. command (Self-Monitoring, Analysis, and Reporting Technology) that allows the
user to read the health information of the SSD. Transcend also define some innovated S.M.A.R.T. features which allows
the user to evaluate the status of the SSD in a much more efficient way.
DEVSLP (optional)
DEVSLP is a new host-controlled SATA interface power state which together enables a SATA host and device to enter
an ultra-low interface power state, including the possibility of completely powering down host and device PHYs.
