Industrial-grade 112-Layer 3D TLC SSDs extend to 8TB
Industrial-grade 112-Layer 3D TLC SSDs from Innodisk have the world’s highest capacity up to 8TB and PCI Gen4 support

Innodisk has launched a new range of industrial solid state disks based on 112 layer 3D NAND chips for densities up to 8Gbytes

The 112-layer SSDs include the SATA 3TG6-P and 3TE7 series, as well as the PCIe Gen3x4 and Gen4x4 series. Compared to the previous 96-layer technology that offered a maximum of 2TB storage, the new 112-layer PCIe Gen 4x4 series increase the capacity to 8TB for U.2 SSD, the highest in the industry, while increased the capacity to 4TB for M.2 (P80).

Beyond capacity increases, 112-layer is also faster, with the PCIe Gen 4x4 series reaching speeds up to 7500/6700 MB/s (8CH) and 3800/3000 MB/s (4CH). The increase in performance meets the growing needs of AIoT applications and industries in 5G, edge computing, deep learning, smart surveillance and smart medical where speed and higher capacity support are critical.

Reliability is paramount, so a two-pronged approach of ECC correction by LDPC within a page and RAID between blocks provides a double layer of protection for greater data security in the 112 layer chips that use three bits per cells.

Consistent and stable linear performance is implemented through a direct write mode that reduces performance drops and WAF. The 112-layer series also features better endurance, greater data security with built-in iDataGuard and iPowerGuard, enhancing compatibility and protection in critical power environments and ensuring sudden power loss data integrity.

Innodisk estimates mass production of 112-Layer 3D TLC series in Q3 2021 to worldwide customers with industrial lifetimes.
