The N342 NGFF (M.2) Series SSD (solid state Drive) fully consists of semiconductor devices using NAND Flash Memory which provide high reliability and high performance for a storage media. The case-less NGFF (M.2) design is significantly smaller than a 2.5-inch Hard Disk Drive. This design makes it ideal for small form factor computing platform such as notebooks.

The N342 NGFF (M.2) Series SSD product electrically complies with the SATAIII standards and is electrically compatible with a serial ATA disk drive. In order to meet the high quality, the NGFF (M.2) Series SSD products utilize Multi-Level Cell TLC/MLC/3D NAND Flash Memory.

Moreover, to ensure the data integrity, many advanced technologies are used such as dynamic bad block management, dynamic and static wear-leveling, and error correction code (ECC). The NGFF (M.2) Series SSD drastically outperforms conventional Hard Disk Drives. In addition, the NGFF(M.2) Series could also provide rugged features in industrial PC under an extreme environment with a high MTBF.

Reliability Specification

(1) LDPC ECC Descriptions

The LDPC ECC engine executes parity generation and error detection/correction features, and enhances decoding throughput and data reliability. With LDPC of correction capability 1e-2 RBER, the hard and soft decoding mechanism provides powerful error and correction. Hence the SM2258XT can enhance the endurance and retention of TLC NAND and extends the SSD lifespan.

(2) RAID Protection

In case of uncorrectable errors occurring within a superblock (a pre-defined area which consists of a particular set of blocks across physical NAND units), the RAID engine recovers the uncorrectable error clunk by using a certain storage space of parity bits. Incorporated with LDPC, the RAID ensures a comprehensive lever of data integrity while providing a broad range of RAID overhead protection.

(3) Data Security

Security commands can be used to lock and unlock the drive by password or through a hardware switch. For those users who require the highest level of security. the MCU provides an enhanced data security option. By utilizing the latest data management techniques such as AES, the full data encryption on SSD can eventually ensure the security of confidential data and information.

(4) SLC Caching

The intelligent SLC caching algorithm enables the NAND flash memory to operate in SLC mode and hence enhances write performance of SSD.

(5) SMART

The MCU supports SMART commands that allow users to read spare and bad block information. The users can thus evaluate drive health at run time and receive an early warning before the drive life ends.

(6) Enhanced Security
Real time full drive encryption with Advanced Encryption Standard (AES). Hardware SHA 256 and True Random Number Generator(TRNG)
