INTRODUCTION
Gen5 SSDs represent the most aggressive jump in consumer storage performance to date, pushing PCIe bandwidth into territory that routinely exceeds 10 GB/s and demanding far more from controllers, cooling, and system design. They’re fast, power‑hungry, and built for workloads that thrive on extreme parallelism. Sitting in that new performance tier is the latest EXCERIA PRO G2 2TB Gen5 M.2 NVMe SSD by KIOXIA.
KIOXIA is a world leader in memory solutions, dedicated to the development, production and sale of flash memory and solid-state drives (SSDs). In April 2017, its predecessor Toshiba Memory was spun off from Toshiba Corporation, the company that invented NAND flash memory in 1987. KIOXIA is committed to uplifting the world with "memory" by offering products, services and systems that create choice for customers and memory-based value for society. KIOXIA's innovative 3D flash memory technology, BiCS FLASH™, is shaping the future of storage in high-density applications, including advanced smartphones, PCs, automotive systems, data centers and generative AI systems.
The EXCERIA PRO G2 is currently available in three capacities (1/2/4TB) and is based on the SM2508 NVMe 2.0 controller by Silicon Motion (6nm lithography) which KIOXIA has paired with their very own BiCS8 218-layer 3D TLC NAND flash and 2GB of LPDDR4X DRAM (2133MHz/4266MT/s) for the 2TB model. The Silicon Motion SM2508 NVMe 2.0 controller features an quad-core ARM Cortex R8 CPU with support for 4 PCIe lanes of 32Gb/s data transfer speed (Gen5 x4), 8 NAND channels with a speed of up to 3600MT/s per channel and packs various technologies including end to end data path protection, programmable firmware interface, SRAM ECC & CRC parity, Innovative LDPC ECC engine, embedded programmable RAID, real-time full-drive AES 128/256bit encryption, hardware SHA 256/384 and TRNG, secure boot for FW authentication, built-in smart clock-gating mechanism (highly efficient power consumption), ONFI 5.0 and Toggle 5.0 support and TCG Opal 2.0 compliance. Moving to endurance KIOXIA reports an MTTF of 1.5 million hours and an TBW of 600 for the 1TB capacity, 1200 for the 2TB capacity and 2400 for the 4TB capacity. Finally, KIOXIA covers the entire EXCERIA PRO G2 line with a 5-year limited warranty.
