KIOXIA EG7 Series SSDs Bring QLC Storage to Mainstream PCs

Client SSD  ◇  Consumer

KIOXIA America has unveiled the EG7 Series, a new family of client SSDs that brings its BiCS FLASH generation 8 QLC with CMOS directly Bonded to Array (CBA) technology to this segment for the first time. KIOXIA says the new series is designed to help PC manufacturers bring high-performance, power-efficient storage to a wider range of systems at a more accessible price point. Capacity options will include 512GB, 1TB, and 2TB models.

KIOXIA EG7 Series Performance and Main Features

The EG7 Series uses 4-bit-per-cell (quadruple-level cell) NAND flash. QLC storage is typically used in lower-cost systems, though it has long faced skepticism about whether it can keep pace with TLC-based drives in everyday performance. KIOXIA is positioning the EG7 Series as a response to that skepticism, saying the new SSDs can deliver TLC-level performance while lowering the total cost of ownership for PC makers building mainstream and more price-conscious systems.

For performance, the drives offer up to 1,000 KIOPS for random reads and writes. Sequential read speeds reach up to 7,000MB/s, while sequential write speeds go as high as 6,200MB/s. This places the EG7 Series in the range of modern PCIe Gen4 client SSDs.

The EG7 Series also supports the NVMe 2.0d specification, which KIOXIA says will provide PC OEMs with added flexibility in device management and overall system design.

KIOXIA EG7 Series Form Factors, Design, and Security

KIOXIA is offering the drives in several M.2 form factors: Type 2230, Type 2242, and Type 2280. That range allows the EG7 Series to fit in compact devices with tight board space, as well as in more conventional notebook and desktop configurations. The smaller 2230 and 2242 formats are important because thin-and-light systems and compact PCs often use shorter SSD layouts.

Metric 512GB 1024GB 2048GB
Sequential Read 6,400 MB/s 7,000 MB/s
Sequential Write 5,000 MB/s 6,000 MB/s 6,200 MB/s
Random Read 550,000 IOPS 850,000 IOPS 1,000,000 IOPS
Random Write 850,000 IOPS 950,000 IOPS 1,000,000 IOPS

The EG7 Series also uses a DRAM-less design. Rather than relying on onboard DRAM, the drives use Host Memory Buffer (HMB) technology, which taps into a portion of system memory to help manage SSD functions. This design is common in more budget-conscious storage products, and can help lower the total cost of ownership and reduce power use without sacrificing responsive performance.

The drives support TCG Opal version 2.02 self-encrypting drive functionality, which is important for business systems that require hardware-based security.

Storage vendors are pushing higher-density flash into a wider range of devices as manufacturers seek more capacity without adding significant system costs. So, the EG7 Series gives OEMs another option for mainstream PCs that need to balance performance, power efficiency, and affordability.

KIOXIA EG7 Series Availability

The EG7 Series is currently sampling with select PC OEM customers. Systems with the new SSDs are expected to begin shipping in the second quarter of 2026.
