Continuing this line of industry firsts, SK hynix showcased samples of its 321-layer 1 Tb 4D NAND, which offers a 59% improvement in productivity compared with the previous generation 238-layer, 512 Gb NAND chips. This improvement was realized by technological developments that enabled the stacking of more cells and a larger storage capacity on a single chip, thereby increasing the total capacity of a single wafer.

The groundbreaking 321-layer NAND product was later presented at SK hynix’s booth along with other NAND solutions, including the company’s PCle³ Gen5 enterprise SSD (eSSD) called PS1030 which utilizes V7 NAND. The PS1030, which was applied to a supermicro server for the demonstration, delivers the fastest sequential read speed in the industry—14,800 MB/s. It also offers a random read performance of 3,300 kIOPS⁴, highlighting its specifications as a high-performance eSSD.

²Charge trap flash (CTF): Unlike floating gate, which stores electric charges in conductors, CTF stores electric charges in insulators, which eliminates interference between cells, improving read and write performance while reducing cell area per unit compared to floating gate technology.

³Peripheral Component Interconnect Express (PCle): A serial-structured, high-speed input/output interface used on the motherboard of digital devices.

⁴Thousand Input/Output Operations Per Second (kIOPS): A measure of how many read and write operations a storage device can perform in a second.

Visitors to the SK hynix booth could also see another one of the company’s SSDs, the PCIe Gen4 PC811.  Applied to a PC for the demonstration, the PC811 is SK hynix’s first V8 NAND-based mainstream client SSD (cSSD). Other SSDs on show included its high-speed Platinum P41, ultra-low power Gold P31, and the company’s first portable SSD for consumers, SK hynix Beetle X31.
