- Polish storage vendor introduces 122.88 TB PCIe 5.0 SSD aimed at immersion-cooled servers
- Drive targets ultra-high capacity workloads with QLC NAND and modest endurance ratings
- Launch appears quietly in technical materials rather than through major industry announcements
A little-known Polish storage company has quietly introduced an enterprise SSD designed for immersion-cooled data centers that offers capabilities that push far beyond what most operators use today.
Goodram Enterprise, which serves 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 a high-profile launch.
The drive belongs to the DC25F series and uses QLC NAND in an E3.S and E3.L form factor. Both versions target servers designed for direct liquid immersion rather than conventional air cooling.
Built to withstand prolonged submersion
Sequential performance is rated at up to 14.6 GB/s for reading and 3.2 GB/s for writing. Random performance figures are around 3,000K IOPS for reads and 35K IOPS for writes, so it’s clearly designed for capacity rather than speed.
Endurance is rated at 0.3 driving writes per day over five years. That puts it in line with other ultra-high-capacity enterprise QLC drives intended for cold and hot data tiers.
The immersion angle is central to the design. Goodram Enterprise claims that the company’s 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 impacts not found in air-cooled racks. The company says its drive is built to withstand prolonged submersion without electrical degradation.
The 122.88TB model sits alongside a wider range of PCIe Gen4 and Gen5 enterprise SSDs. Capacities across the range range from less than 2 TB to more than 120 TB, covering TLC and QLC options.
While immersion cooling is still a niche outside of hyperscale and research implementations, interest continues to grow as rack power density increases. PCIe 5.0 SSDs add additional 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, despite the combination of capacity and interface placing the drive among the largest PCIe 5.0 SSDs launched to date.
Separate efforts elsewhere show that immersion and liquid cooling for storage are not limited to a single vendor or approach.
DapuStor has talked publicly about deploying immersion-rated SSDs in telecom server platforms, while Solidigm has demonstrated liquid-cooled NVMe drives designed for dense AI servers, using cold plates instead of liquid inside the drive itself.
Previous experiments from PC-focused vendors like XPG also explored water-cooled PCIe 5.0 SSDs, though these targeted enthusiast systems rather than data centers.
