1. Intel: SSD will replace HDD and become the mainstream market in 2022

At present, traditional mechanical hard drives (HDD) are still storage options for many companies, because their total cost of ownership (TCO) is lower than solid state drives (SSD), so they can spend less. However, Intel recently stated that as the overall cost of SSDs gradually declines, by 2022, the TCO of SSDs and HDDs will be a golden cross, which means that the cost of purchasing SSDs will be less and see more PLC NAND applications.

According to a foreign media report from Blocks & files, Rob Crooke, director of Intel NAND products and solutions, said at the "Intel Memory and Storage Moment 2020" forum that the continuous development of multi-layer 3D NAND will make the total cost of ownership of SSDs in about one year After catching up with HDD; this will make SSD more widely used in the storage market to replace HDD.

Rob Crooke added that PLC NAND, in particular, has the advantages of higher density and lower storage cost per unit capacity than other storage technologies. Therefore, Intel will actively develop toward PLC and has made relevant plans.

2. Intel is optimistic about the future of NAND flash memory

On October 20 this year, Intel and SK Hynix also updated their announcement on their official website. SK Hynix will pay US$9 billion to acquire Intel’s NAND flash storage business. This acquisition includes Intel’s NAND SSD business, NAND components and wafer business, And its NAND flash memory manufacturing plant in Dalian, China, is expected to be handed over to Hynix by the end of 2021.


In addition, Intel will continue to produce NAND wafers at the Dalian Memory Factory and retain its NAND wafer manufacturing and design-related intellectual property rights until the transaction is finalized in March 2025. As for the Optane business, Intel will continue to retain it.

However, Intel, which sells NAND flash memory business, still demonstrated its NAND strength on the memory storage day, and launched three industry-leading new NAND SSDs, including Intel SSD 670p, Intel SSD D7-P5510 and Intel SSD D5 -P5316, these three NAND SSDs all use 144-layer storage units, but they are oriented to different usage scenarios.

For 3D NAND, the number of flash layers is the most intuitive dimension to measure the advancement of flash memory. Intel said: "All 3D NAND manufacturers are increasing the number of layers in order to store more data per square millimeter of NAND wafers, increase the capacity of each wafer, and ultimately reduce costs."

According to Intel’s introduction, the 670p is Intel’s next-generation 144-layer QLC 3D NAND solid state drive for mainstream computing on the client side. It provides end-to-end data protection with Pyrite 2.0 security and support for power failure notifications to help improve IT efficiency and Improve the actual use of PC clients and the manageability of applications.


SSD D7-P5510 is the world's first 144-layer TLC NAND solid state drive to market. It is a large-capacity alternative product for cloud storage and can help accelerate various cloud data center workloads. With U.2 form factor and 3.84 TB or 7.68 TB capacity, it has improved health monitoring.

SSD D5-P5316 is the industry's first data center-level solid state drive with 144-layer QLC NAND, which can optimize and accelerate traditional storage capacity, and has two forms of U.2 and E.1L. Compared with the hard disk, the read performance is improved by 200%, the random random read performance is improved by 38%, and the latency is reduced by 48%. It is worth mentioning that this is also the first 30.72TB PCle solid state drive, which can realize a complete PB in a rack unit or 1 PB in 1U.

Intel is optimistic about the future of NAND flash memory. Rob Crooke, senior vice president and general manager of the NAND Products and Solutions Division, said that from the perspective of total cost of ownership, the cost per GB (gigabyte) of solid-state disks is very close to the cost of hard disk drives, and the two are expected to be the earliest It will reach consensus in 2022.

"We merged two cooperative companies with strategic intentions of memory, and the total NAND revenue will exceed $10 billion per year, and it has amazing growth prospects." Rob Crooke said. 

The first is SSD 670p, a 144-layer QLC 3D NAND SSD. It is used for mainstream computing on the consumer side. It provides end-to-end data protection and supports Pyrite 2.0 security and power failure notifications. It helps to improve IT efficiency on the PC consumer side. And the manageability of the device that actually uses the application.

The SSD D7-P551 uses a 144-layer TLC NAND design to help accelerate cloud data center workloads in all directions. It provides 3.84TB or 7.68TB space capacity in U.2 form factor. With improved device health monitoring, it provides greater flexibility in multi-tenant and virtualized environments, and has a new version of algorithms and functions tailored for cloud workloads. It is expected to be available at the end of 2020.

Finally, the SSD D5-P531, which also uses a 144-layer QLC design, is developed for the optimization and speed improvement of traditional large-capacity storage devices. It is expected to be available in the first half of 2021. Each die has a capacity of 128GB, which can increase read performance by up to 200%, and increase random read performance by 38%. Compared with traditional hard disks, it can reduce access latency by 48%. It will provide 15.36TB and 30.72TB Capacity, with U.2 and E1.L appearance specifications.
