Enterprise SSDs with huge storage volumes and fast PCIe 5.0 interfaces are determining the new generation. SK Hynix also wants to have a say and presents the PS1012 series, which initially offers 61 TB and 13 GB/s with QLC storage. Next year there will be 122 TB and at some point even 244 TB.
SK Hynix offers PS1012 for maximum storage space
While the PEB110 and PS1010 with TLC NAND and PCIe 5.0 are aimed at the highest performance, the new PS1012 with QLC memory is aimed at the highest storage capacities. The series will initially reach 61 TB, until a 122 TB variant follows in the third quarter of 2025. The 244 TB mark is expected to be reached later. The new 321-layer NAND, which entered mass production in November, will be used.
13 GB/s should be possible via PCIe 5.0
According to the images shown, the PS1012 uses the 2.5-inch form factor with a U.2 connection. Throughput of up to 13 GB/s for sequential reading should be achieved via PCIe 5.0 x4 as an interface. Information on write performance or maximum IOPS for random access is not yet provided. The throughput would be slightly higher than the recently launched Micron 6550 ION with 61 TB and 12 GB/s.

SK Hynix highlights its cooperation with Solidigm, the company resulting from the former flash division of Intel, a subsidiary of SK Hynix and specialized in QLC memory. The Solidigm D5-P5336, for its part, offers 61 TB and should be available with 122 TB in early 2025.
However, a key difference is that the D5-P5336 still uses PCIe 4.0, while the SK Hynix PS1012 achieves higher transfer rates thanks to PCIe 5.0. Phison aims to achieve up to 122 TB and even higher transfer rates, up to 14.6 GB/s with the Pascari D205V. QLC storage is to be expected here as well. This type of storage is also used in the Samsung BM1743, which itself offers 61 TB and later 122 TB. Western Digital also wants to upgrade to 122 TB next year. By then, the SSD division will already be transformed into an independent SanDisk with a new logo.
