- SK Hynix shows off its 245TB PS1101 Gen5 SSD for cloud and AI workloads
- PS1101 shown alongside smaller client and Gen5 SSDs
- High-capacity PCIe Gen5 SSDs emerge as storage makers prepare larger models for 2026
Enterprise SSD capacities continue to increase as manufacturers push storage density to new limits.
In 2024, we saw several 123TB models from Solidigm, Phison, WD, and Samsung, and this year has already brought announcements of 245TB PCIe Gen5 SSDs from Kioxia and Huawei, along with an even larger model from Sandisk.
Kioxia expanded its line of LC9 series enterprise SSDs with a 245TB model, Huawei introduced the OceanDisk LC560, while Sandisk revealed a 256TB SSD using its new UltraQLC flash memory.
SK Hynix shows off the PS1101
Other storage manufacturers, including Solidigm, Samsung and Micron, are expected to introduce 245TB models in 2026, while Samsung is also preparing a 512TB PCIe Gen6 SSD for 2027.
SK Hynix has now joined the high-capacity SSD field with the PS1101, a 245TB PCIe Gen5 enterprise drive it revealed at the Dell Technologies Forum in Seoul.
Like other high-capacity drives, it is designed for data centers that handle large AI workloads rather than desktop PCs.
The PS1101 uses QLC NAND and the PCIe Gen5 interface to deliver high data transfer speeds while keeping power usage and space requirements low.
The unit is built in the E3.L form factor and was modestly labeled “World’s Best” at the company’s showcase.
It will focus on large-scale AI servers and cloud environments where rack capacity and thermal efficiency are critical.
The drive was introduced alongside other Gen5 SSDs, including PS1010, PS1012, and PEB110.
The 61TB PS1012 offers twice the bandwidth of comparable Gen4 SSDs, while the PEB110 E1.S model supports capacities from 2TB to 8TB using TLC NAND.
SK Hynix also introduced its PCB01 client SSD, capable of 14 GB/s sequential read speeds and 12 GB/s write speeds, for on-device AI and high-performance computing.
A compact PVC10 M.2 2230 model, designed for low-power systems, was also on display, as were SK Hynix’s next-generation DRAM and HBM products, including HBM4 memory running at 2TB per second.
With the PS1101, SK Hynix joins a growing group of storage manufacturers offering ultra-dense enterprise SSDs. The Korean memory giant did not announce a production schedule, but it should be early 2026.
