CES 2026: Kioxia launches new BG7 SSDs with improved efficiency
At CES this week Kioxia is launching its BG7 series SSDs at CES 2026, marking the first client‑focused drives to use the company’s eighth‑generation BiCS Flash paired with its new CMOS‑Bonded‑to‑Array (CBA) architecture. The update targets thin‑and‑light notebooks, compact desktops and OEM systems, promising stronger performance and improved power efficiency over the previous BG6 generation.
The move to BiCS Flash Gen 8 brings a notable uplift in throughput. Kioxia rates the BG7 for up to 7,000MB/s sequential reads and as much as 1,000,000 IOPS in random workloads, translating to roughly a 10% improvement in random performance and around 16% in sequential reads compared to BG6. Power efficiency sees the biggest generational jump with sequential‑write efficiency up by approximately 67%. This improvement is achieved through a combination of CBA‑enhanced memory cells, refined control circuitry and an updated SSD controller.
The BG7 series also expands the physical formats available. Alongside the familiar M.2 2230 and 2280 options, Kioxia is adding a new M.2 2242 model to support a wider range of OEM designs and space‑constrained systems. NVMe 2.0d support has been introduced as well, giving system builders finer control over power states and device behaviour.
As with previous entries in the BG line, the BG7 remains a DRAM‑less design, relying on Host Memory Buffer (HMB) to keep costs down while maintaining responsiveness. Capacities span 256GB, 512GB, 1TB and 2TB, and the drives connect over PCIe 4.0. Security‑conscious deployments can opt for models supporting TCG Opal 2.01 self‑encrypting drive functionality.
KitGuru Says: With DRAM being in short supply for consumer-oriented products at the moment, DRAM-less SSDs should become more prominent across the consumer market.
