SK hynix press release about its upcoming PCB01 PCIe 5.0 SSD was a bit light on details and Anandtech got a closer look at the upcoming drive at GTC 2024. Not entirely unsurprising, the drive will be called the Platinum P51 rather than the PCB01, which is a continuation of the branding SK hynix is using for its current range of SSDs. As we already know, it'll feature a custom SK hynix controller and no further data was revealed to Anandtech, but the publication did manage to get some more details with regards to the NAND flash used.

The Platinum P51 is SK hynix first consumer SSD with its new-ish 238-layer 4D NAND flash based on the company's PUC (peri. under cell) technology, which places the peripheral circuits under the cell array. The official performance figures of the Platinum P51 appears to be somewhat lower than the press release from earlier today stated, with sequential read speeds of up to 13.5 GB/s and sequential write speeds of 11.5 GB/s. SK hynix will apparently release the drive in the typical SSD sizes of 500 GB, 1 TB and 2 TB. It'll be interesting how SK hynix in-house controller will compare to the second generation of Phison E26 based drives paired with Micron B58R NAND flash once it becomes available later this year.

SK hynix Inc. today reported financial results for the second quarter of 2023. The company recorded revenue of 7.306 trillion won, operating loss of 2.882 trillion won (with operating margin of negative 39%), and net loss of 2.988 trillion won (with net margin of negative 41%) for the three-month period ended June 30, 2023.

"Amid an expansion in generative artificial intelligence (AI) market, which has largely been centered on ChatGPT, demand for AI server memory has increased rapidly," the company said. "As a result, sales of premium products such as HBM3 and DDR5 increased, leading to a 44% sequential increase in revenue for the second quarter, while operating loss narrowed by 15%."

SK hynix Inc. announced today that it has started mass production of its 238-layer 4D NAND Flash memory, following the development in August 2022, and that product compatibility test with a global smartphone manufacturer is underway. "SK hynix has developed solution products for smartphones and client SSDs which are used as PC storage devices, adopting the 238-layer NAND technology, and has moved into mass production in May," the company said. "Given that the company secured world-class competitiveness in price, performance and quality for both 238-layer NAND and the previous generation 176-layer NAND, we expect these products to drive earnings improvement in the second half of the year."

The 238-layer product - the smallest NAND in size - has a 34% higher manufacturing efficiency compared to the previous generation of 176-layer, resulting in a significant improvement in cost competitiveness. Besides, with a data-transfer speed of 2.4 Gb per second, a 50% increase from the previous generation, and approximately 20% increase in read and write speed, the company is confident that it will be able to deliver an improved performance to the smartphone and PC customers using this technology.

Yesterday SK Hynix reported its Q1 2023 results and to say that they were abysmal is being kind, as the company reported a 3.4 trillion won operating loss, or just over US$2.5 billion. That's no small hit to take for any company, especially when it's only the performance for a single quarter. However, SK Hynix is apparently trying to see its situation from a positive perspective and believes that the memory chip market will rebound in the second half of this year. The positive outlook isn't just based on what SK Hynix believes though, as various analysts and securities companies believe in an upswing in the second half of the year.

That said, Micron, one of SK Hynix main competitors, has a more drab outlook for the remainder of 2023 and is expecting a tough year ahead. SK Hynix is expecting production cuts by itself, Micron and Samsung to start to take effect sometime in the second quarter this year, which should see inventory drop to more normal levels for all three companies. SK Hynix is also expecting to see a higher demand for DDR5 DRAM later this year, especially in the mobile and server market space. Finally, SK Hynix is hoping that its customers will buy higher density memory products this year, replacing older, lower density solutions, be that DRAM or NAND flash related. SK Hynix is expecting to launch its Gen 5 10 nm DRAM and 238-layer NAND sometime next year, which the company is also hoping will bring more income to its coffers, but the company still has to make it through the rest of 2023 first.

SK hynix Inc. reported today revenues of 10.98 trillion won, operating profit of 1.66 trillion won (with OP margin of 15%), and net income of 1.1 trillion won (with net income margin 10%) in the third quarter of 2022. Sales and operating profits decreased 20.5%, 60.5% respectively QoQ. SK hynix analyzed that revenues fell QoQ as both sales volume and price decreased due to sluggish demand for DRAM and NAND products amid worsening macroeconomic environment worldwide. In addition, SK hynix explained that despite the company improved cost competitiveness by increasing the sales proportion and yield of the latest 1anm DRAM and 176-layer 4D NAND, operating profit also decreased due to greater price drop than cost reduction.

SK hynix diagnosed that the semiconductor memory industry is facing an unprecedented deterioration in market conditions as uncertainties in the business environment continued. The deterioration occurred as the shipments of PCs and smartphone manufacturers, which are major buyers of memory chips, have decreased.

The first batch of PCIe 5.0 SSDs are all likely to be based on Phison's PS5026-E26 controller, which offers eight NAND channels, capable of supporting NAND speeds of up to 2400 MT/s. Phison's own figures for the controller are 13 GB/s writes and 12 GB/s reads, with up to 1.5 million random read IOPS and 2 million random write IOPS. However, as we've already seen from various SSD brands, many PCIe 5.0 SSDs won't exceed 10 GB/s when it comes to the sequential read/write speeds. This is because the current NAND flash simply isn't fast enough to saturate the PCIe 5.0 bus, which is capable of 15.75 GB/s. That said, Micron's 232-layer 3D NAND should be able to boost the performance up to 12.4 GB/s based on the numbers Gigabyte announced for their Aorus Gen 10000 SSD.

Based on an article over at Tom's Hardware, we shouldn't expect too many drives that exceed 10 GB/s sequential writes at launch, due to most drives using 176-layer 3D NAND flash, that is limited to 1600 MT/s. As such, it might be wise to hold off on buying the first generation of PCIe 5.0 drives and wait for better availability of 232-layer 3D NAND, as beyond Micron, SK Hynix is expected to have a 238-layer 3D NAND flash in the market sometime in the first half of 2023. If you're not really eager to have the fastest SSD out there for pure bragging rights, it would seem that mid 2023 might be the right time to get a PCIe 5.0 SSD.

SK hynix Inc. announced today that it has developed the industry's highest 238-layer NAND Flash product. The company has recently shipped samples of the 238-layer 512Gb triple level cell (TLC) 4D NAND product to customers with a plan to start mass production in the first half of 2023. "The latest achievement follows development of the 176-layer NAND product in December 2020," the company stated. "It is notable that the latest 238-layer product is most layered and smallest in area at the same time."

The company unveiled development of the latest product at the Flash Memory Summit 2022 in Santa Clara. "SK hynix secured global top-tier competitiveness in perspective of cost, performance and quality by introducing the 238-layer product based on its 4D NAND technologies," said Jungdal Choi, Head of NAND Development at SK hynix in his keynote speech during the event. "We will continue innovations to find breakthroughs in technological challenges."
