1,000TB SSDs could become commonplace by 2030, thanks to Samsung’s 1,000-layer NAND technology

The prospect of an SSD with 1,000-layer NAND is particularly enticing at a time when many storage technologies (hard drives, silica, tape, DNA, etc.) are trying to supplant the medium as the most important property. caught in the world of bits and bytes. Samsung plans to pack more than 1,000 layers into its most advanced NAND chip by 2030. 1TB TLC V-NAND technology will soon be available as Samsung accelerates the transition to QLC technology.

Although it hasn’t revealed whether these will be actual products available on the shelves, products shipped to customers (like Teamgroup) or samples from its labs. Either way, the prospect of having an SSD with 1,000 NAND layers is particularly enticing at a time when many storage technologies (hard drives, silica, tape, DNA, etc.) are trying to supplant the support as the hottest property in the world of bits and bytes.

The best hard drives, also known as HDDs, are reliable, have a large capacity, and are generally less expensive than an SSD (Solid State Drive) of the same capacity. However, even the worst SSD will outperform the best HDD in terms of file transfer rates and overall performance, simply because of the technology used, so the best SSD is absolutely going to blaze the best HDD out there. world.

In our environment, boot disks do more than start up storage servers: they also store log files and temporary files produced by the storage server. Each day, a boot drive will read, write, and delete files based on activity on the storage server itself. In our first storage servers, we exclusively used hard drives for booting. We started using SSDs in this capacity in the fourth quarter of 2018. Since then, all new storage servers, and those with failed HDD boot disks, have been equipped with SSDs.

Backup and cloud storage company Backblaze has released data comparing the long-term reliability of solid-state storage drives and traditional spinning hard drives in its data center. Based on data gathered since the company started using SSDs as boot drives in late 2018, Backblaze cloud storage evangelist Andy Klein released a report yesterday showing that the company’s SSDs are falling fails at a much lower rate than its hard drives as the drives age.

These findings are drawn from Backblaze’s latest report detailing the reliability statistics of the drives used in its infrastructure, and in this case, it’s only the second such report to focus on SSDs, after the one the company published in march.

SK Hynix and Micron announced in early 2022 that they would release 238 and 232 layer products respectively, which – on paper – will significantly lower the cost per trabyte for solid state hard drives. However, it should be noted that these odds are likely to be elastic depending on global demand and supply. The current global economic situation could force companies to reduce their R&D activities and lengthen the intervals between product launches.

The average price of SSDs is at an all time low, with 2TB SSDs widely available for less than $100. Experts expect SSDs and HDDs to reach parity in some capacities by next year, with the lucrative enterprise market the only one more or less immune at the moment.

“SK hynix has secured world-leading competitiveness in terms of cost, performance and quality by introducing a 238-layer product based on its 4D NAND technologies,” said Jungdal Choi, head of NAND development at SK hynix. Contrary to expectations, the new 238-layer NAND will make its first appearance on client devices, which is sure to get content creators and PC gamers excited. It is only later that the new chip will arrive on smartphones and high-capacity servers.

Regarding Micron’s specific plans for its new 232-layer 3D NAND device, the company’s executive vice president of technology, Scott DeBoer, said the following: “We optimized the technology based on what we we need to make the world’s fastest gre NAND and SSD products for data centers and customers. The combination of controllers, both internal and external, has been a strong part of our move towards vertical product integration to ensure that we have optimized NAND technology and controllers for what we need to deliver products. future leadership.

Micron says it is already working closely with its industry partners to ensure its Layer 232 device is properly supported, which should accelerate the development of new drives based on this technology. To fairly compare SSDs and HDDs, Backblaze controlled for the average age of the two groups, so SSDs that were on average one year old were compared to HDDs that were on average one year old, and so on. . The graph below shows the results up to the second quarter of 2021, taking into account the average age of the two groups.

SSDs equipped with the new 3D NAND flash are expected to hit the market in 2023. With Samsung, more layers not only mean cheaper products, but also higher storage densities. Currently, the largest SSD in the world is a 3.5-inch 100TB model from Nimbus Data, which uses a 64-layer MLC chip. A 1024-layer TLC/QLC chip would have 16 times as many layers, which puts a 1PB (1000TB) SSD in the realm of possibility before the end of this decade. We believe it is possible to scale this design space with granular supports in the range of 4 Tb/in2 to 6 Tb/in2, and then plan to add patterns in one dimension using ordered grain supports, said John Morris, chief technology officer at Seagate.

We believe this will be a springboard for media to open up the 5 7 Tb/in2 range. Then we’ll move to fully structured media to achieve densities of 8 TB/in2 and beyond. With the areal density CAGR just presented, we have the possibility of reaching 10 TB per disk by 2030. So that represents our outlook for the technological limits for the next 10 to 15 years. But who needs such a capacity? Cloud storage companies like iDrive or BackBlaze, hyperscalers like Google or Microsoft, social networks like Instagram or Facebook.
