96-Layer 3D TLC Reaches Embedded & Industrial NVMe SSDs: Transcend Reveals MTE662T

Though, as always, it takes some time for newer technologies to filter down into the conservative embedded/industrial market, the time has finally come for 96-layer 3D TLC NAND. SSD maker Transcend recently introduced its high-performance MTE662T SSD, one of the world’s first 96-layer 3D TLC-based NVMe drives aimed at commercial and industrial environments. And with sequential read speeds of up to 3400 MB/s, the drive is among the fastest in the segment.

When it comes to SSDs for applications that work 24/7 and/or in harsh environments, predictability and reliability are two things that matter the most, so the devices use appropriate components, are tailored for a particular use case, and have to pass rigorous tests. Transcend’s MTE662T M.2-2280 SSD is designed for embedded or ‘mild’ industrial applications, so it can handle operating temperatures between 0ºC and 70ºC for prolonged periods, can survive 5% ~ 95% RH non-condensing humidity, and endure 2.17 G (peak to peak) vibration with a 10 Hz ~ 700 Hz frequency.

The Transcend MTE662T carries 256 GB, 512 GB or 1 TB of 96-layer 3D TLC BiCS4 memory from Toshiba. The SSD is controlled by by an undisclosed high-end controller with eight NAND channels that supports NVMe 1.3 feature set, an LDPC-based ECC as well as DRAM caching. As far as performance is concerned, the drive promises up to 3400 MB/s sequential read speeds, up to 2300 MB/s sequential write speeds (when pSLC cache is used), as well as a peak read/write random IOPS rating of 340K/355K.

When it comes to endurance and reliability levels, Transcend’s MTE662T SSDs can handle from 550 TB to 2,0 TB written over a three-year warranty period, depending on the drive's capacity. This is not a particularly high rating, but far not all embedded and commercial applications are write intensive. As for MTBF, Transcend has rated the drive for 3,000,000 hours.
