SANDISK 8th Generation BiCS QLC CBA NAND
Flash memory continues to evolve through both higher layer counts and architectural innovation. For example, the 6th generation SANDISK BiCS NAND builds the memory cells with 162-layers and uses CMOS Under the Array as a single wafer while the 8th generation SANDISK BiCS NAND deploys CMOS Bonded to Array (CBA) and 218-layer memory cell to vastly improve performance and power consumption. Furthermore, 8th generation SANDISK BiCS NAND increases bit density by more than 50% over previous generations, packing more data into a smaller physical die using lateral and vertical shrink techniques.
For QLC NAND, CBA redefines what’s possible with SSDs. The combination of higher performance and power efficiency enables QLC-based SSDs to meet the growing demands in business and consumer PCs for higher capacities and higher performance for application workloads all while helping extend battery life in laptop PCs and mobile devices.
QLC vs. TLC
QLC and TLC are both important in data storage.
For OEMs and other stakeholders, the right approach depends on each technology’s strengths — and the best results for users depend on knowing how QLC and TLC compare.
Higher capacities
QLC increases bit density by storing four bits per cell, offering more space than TLC’s three bits per cell.
Cost-efficiency
QLC provides more storage per cell than TLC at a lower cost, making high-capacity solutions more accessible.
Applications advantages
QLC shines in both consumer and commercial applications — like productivity suites, content creation workflows, and even gaming because of the vast improvement in performance similar to that of TLC.
Balanced trade-offs
Sandisk has helped deliver the capacity benefits of QLC while mitigating its traditionally lower endurance and performance.
Who can benefit from 8th Generation SANDISK BiCS QLC CBA NAND?
A QLC SSD built the 8th generation SANDISK BiCS QLC CBA NAND makes for ideal storage for entry and mid-range PCs, providing a compelling combination of high capacity, strong performance, and power-efficiency. These SSDs can fuel the next generation of business or consumer applications including productivity, content creation, and even gaming delivering a user experience without compromise.
System integrators, PC manufacturers, and consumer DIYers can seamlessly integrate these QLC SSDs for business and consumer clients.
Is the 8th generation SANDISK BiCS QLC CBA NAND cost efficient?
Fundamentally, the 8th generation SANDISK QLC CBA NAND can store more bits per memory cell than SANDISK TLC NAND, resulting in 33% higher bit density. A QLC CBA NAND can provide more total density than TLC lowering the total cost per GB.
Because of this, 8th generation SANDISK QLC CBA-based SSDs can be a more cost-effective solution for system integrators, PC manufacturers, and DIYers seeking storage for their budget or simply higher a higher capacity for their growing data.

The SANDISK 8th generation BiCS QLC NAND can help PC manufacturers and consumers get QLC bit density at TLC product speeds without concerns of reliability. Users are generating more content, storing larger files, and demanding greater capacities for their PCs. Sandisk 8th generation BiCS QLC NAND helps enables our SSDs to achieve performance levels comparable to TLC SSDs in many client workloads.
See Chart: PCMark 10 results demonstrate that the SANDISK Optimus™ 5100 NVMe™ SSD, powered by our 8th-generation BiCS NAND, delivers superior performance compared to our TLC-based SSDs.
How does the SANDISK nCache 4.0 technology help QLC?
QLC SSDs can benefit from having an SLC cache to help sustain performance and improve endurance.
With the latest SANDISK nCache 4.0 technology and 8th generation SANDISK BiCS QLC CBA NAND, Sandisk SSDs combine leading edge technologies for our SSDs to help ensure sustained high performance, low power consumption, and durability for PC workloads. Here’s how:
Speed meets capacity
SANDISK nCache 4.0 features a hybrid SLC write cache technology, which writes hot data at high speeds to SLC cache before moving data to QLC, which occurs during idle time. nCache 4.0 helps optimize both burst-write responsiveness and sustained-write performance.
Smart caching
By intelligently managing how data is written to QLC NAND, Sandisk nCache 4.0 can help extend the lifespan of QLC SSDs. This helps minimize the wear on memory cells and helps protect data.
Diverse use cases
Whether you’re creating content or working on your next professional project, Sandisk nCache 4.0 provides high-speed burst write performance QLC SSDs.
Cost-efficient capacity
Sandisk nCache 4.0 paired with QLC translates to more affordable, higher-capacity drives, letting users store more without compromising on performance and reliability.
