Transforming the Economics of Storage

Intel® 3D NAND Technology extends our leadership in flash memory with an architecture designed for higher capacity and optimal performance, a proven manufacturing process providing accelerated transitions and scaling, and rapid portfolio expansion for multiple market segments.

Storage Capacity Empowered by Intel® Innovation

Intel introduces the world’s first PCIe* SSDs with Intel® QLC Technology. Intel® QLC 3D NAND Technology provides up to 33% high areal density1 than its 3D NAND predecessor. It also uniquely features PCIe* acceleration, to deliver a reliable mix of performance, capacity, and value-making it a smart storage solution for both datacenter and client markets.

Intel® QLC Technology leverages current 3D NAND, with a proven 64-layer structure, and adds an additional bit per cell that provides 4bits/cell (QLC), making it the world's highest-density flash memory. Additionally, this technology uses a floating gate cell because it is a reliable, low-cost storage method. Last, Intel® QLC Technology was paired with PCIe*- (NVMe*) technology, to provide up to a 4x performance benefit over SATA interfaces.2

Prepare for the future with Intel QLC-built on reliable Intel® technology and backed by Intel manufacturing leadership.

Finally, SSD Performance Meets Big Business Value

For datacenters, Intel® QLC 3D NAND Technology radically shrinks HDD system footprints.3 Fewer systems to maintain lead to power and cooling savings4, while also reducing operation and capital costs associated with drive replacements.5 And while footprint goes down, performance goes up.6 PCIe* acceleration blasts through SATA bottlenecks7, unleashing the full power of QLC. When coupled with optional Intel® Optane™ technology, Intel® 3D NAND Technology datacenter products deliver even better performance2, accelerating access to data needed most.

Do more, store more, and save more with Intel® QLC Technology featured in the Intel® SSD D5-P4320 SeriesIntel® SSD D5-P4326 Series, and Intel® SSD D5-P4420 Series. Currently shipping in limited quantities.

Amazing Is Now Affordable

Intel® QLC 3D NAND Technology enables consumers to tackle today’s storage needs and prepare for the growing demands of tomorrow. These client SSDs pack in more data than TLC-based storage, allowing up to 2x more capacity in identical footprints.1 Only Intel coupled this game-changing technology with PCIe* to deliver affordable PCIe* performance.

Architected for Capacity and Reliability

Intel® 3D NAND Technology is an innovative response to the industry’s growing demand for data storage capacity. Compared to other available NAND solutions, Intel® 3D NAND Technology is designed on floating gate architecture with a smaller cell size and a highly efficient memory array, which enables higher capacity solutions and high reliability with strong protection from charge loss.

Innovation Leadership

64-Layer Breakthrough

Intel has applied 30 years of flash cell experience to transition NAND from 2D to 3D, multi-level cell (MLC) to tri-level cell (TLC), and 32-layer to our breakthrough 64-layer technology. All of this is done to deliver the highest areal density8 and rapidly grow storage capacities in 3D NAND solutions.

Expansive Portfolio

Built on a Proven Process

With 3D NAND technology, Intel delivers innovative, high-value capabilities into a broad product portfolio. Our experience of designing this architecture into SSD solutions enables us to rapidly improve performance, power consumption, performance consistency, and reliability with each generation.

Manufacturing Scalability

Enabling Disruptive Opportunities

Intel is using manufacturing processes proven by decades of high volume output to build 3D NAND technology. With strong generational synergy across our factory network, Intel expects to grow 3D NAND capacity faster than the market, enabling us to deliver disruptive total cost of ownership and application acceleration to our customer base.
