- Polish Storage Vendor Unveils 122.88TB PCIe 5.0 SSD for Immersion-Cooled Servers
- Drive Targets Ultra-High Capacity Workloads with QLC NAND and Modest Endurance Ratings
- The release appears quietly in technical materials and not through major industry announcements.
A little-known Polish storage company has quietly introduced an enterprise SSD designed for immersion-cooled data centers, offering capabilities far beyond what most operators use today.
Goodram Enterprise, which operates as the data center-focused arm of Wilk Elektronik, has added a 122.88TB PCIe 5.0 drive to its portfolio. The large SSD appears in technical documentation rather than in a high-profile release.
The drive belongs to the DC25F series and uses QLC NAND in an E3.S and E3.L form factor. Both versions are aimed at servers designed for direct liquid immersion rather than conventional air cooling.
Built to tolerate long-term immersion
Sequential performance is up to 14.6 GB/s for reads and 3.2 GB/s for writes. Random performance numbers are around 3,000,000 IOPS for reads and 35,000 IOPS for writes, so it's clearly designed for capacity rather than speed.
Endurance is estimated at 0.3 drive writes per day for five years. This puts it in line with other ultra-high capacity enterprise QLC drives designed for cold and warm data levels.
The angle of immersion is essential for the design. Goodram Enterprise says its enterprise SSDs have been validated with dielectric fluids commonly used in immersion cooling tanks, including Shell and Chevron formulations.
Immersion cooling exposes hardware to chemical, thermal, and material stresses that do not exist in air-cooled racks. The company says its units are designed to tolerate long-term immersion without electrical degradation.
The 122.88TB model is paired with a broader range of PCIe Gen4 and Gen5 enterprise SSDs. Capacities across the line range from less than 2TB to over 120TB, covering TLC and QLC options.
While immersion cooling remains niche outside of research and hyperscale deployments, interest continues to grow as rack power density increases. PCIe 5.0 SSDs add more thermal pressure, making liquid-based approaches more attractive.
What stands out is how little attention this release has received. There was no major announcement cycle, although the combination of capacity and interface places the drive among the largest PCIe 5.0 SSDs released so far.
Other efforts elsewhere show that immersion and liquid cooling for storage are not limited to a single vendor or approach.
DapuStor has publicly talked about deploying immersion-rated enterprise SSDs in telecom server platforms, while Solidigm has demonstrated liquid-cooled NVMe drives designed for dense AI servers, using cold plates instead of fluid within the drive itself.
Previous experiments from PC-focused vendors like XPG also explored water-cooled PCIe 5.0 SSDs, although they were aimed at enthusiast systems rather than data centers.
