Intel® QLC 3D NAND SSD with PCIe* Large, Affordable Capacity. Reliable Storage.

Intel delivers the industry’s first PCIe* QLC 3D NAND SSD for the Data Center1 – a new generation of large, affordable, and reliable drives.

The Intel® SSD D5-P4320 and D5-P4420 deliver big, affordable, and reliable storage to the warm data tier. With 33% more bits per cell than TLC,2 the Intel® QLC 3D NAND SSDs enables 3x storage consolidation3 compared to hard disk drives (HDDs), leading to lower operational costs. As the industry’s first PCIe*-enabled QLC drive for the data center, the D5-P4320 provides the ability to scale to large capacities and deliver the performance needed for storage workload requirements. The D5-P4420 drive offers double the endurance, supporting an even wider range of workloads.

Store More: Big Capacities Store Massive Quantities of Data
The Intel® QLC Technology offers an aerial density advantage of 33% more bits per cell than the prior generation of Intel® 3D NAND SSDs. The result? Higher capacity, costeffective PCIe drives optimized for read-intensive storage workloads. Both the D5- P4320 and D5-P4420 are currently available in a U.2 form factor with 7.68TB capacity.

Save More: High Density Reduces Operational Cost
Today’s data center storage often relies on a mix of HDD and SSD technologies. The Intel® SSD D5-P4320 and D5-P4420 deliver high capacity and lower operational cost for the capacity or “warm” data storage layer traditionally served by hybrid or HDD arrays. With its higher density, Intel® QLC 3D NAND SSD means fewer drives to support, power and cool. In addition, Intel® Data Center SSD have a lower annual failure rate,4 which further reduces costs.

Do More: PCIe Accelerates Workloads at Large Capacities
All QLC-enabled SSDs are not created equal. In addition to massive capacities, the D5-P4320 and D5-P4420 are built on the PCIe* interface, which delivers higher maximum performance than the SATA interface.5 Both SKUs allow for much denser systems while enabling performance per TB to continue scaling well beyond SATA-based QLC SSDs. The Intel® QLC 3D NAND SSDs, when combined with Intel® Optane™ technology, accelerate the speed of frequently accessed data, at the price and capacity of massive storage.

Backed by Intel Experience and Innovation
Intel brings longstanding expertise and leadership in data management to address the capacity and performance issues of today’s data centers. Prepare for the future with PCIe Intel® QLC 3D NAND SSDs, backed by Intel’s technology and manufacturing leadership.
