The Quiet Rise of Immersion Cooling and 122TB SSDs: A Data Center Revolution?
Rack power densities are soaring, and the traditional limits of air cooling are rapidly being breached. While much attention focuses on the latest processors and GPUs, a less-publicized shift is underway in storage – and it’s being driven by the need to dissipate ever-increasing heat. Polish storage vendor Goodram Enterprise recently launched a PCIe 5.0 SSD with a staggering 122.88TB capacity, specifically designed for immersion-cooled data centers, and the quiet nature of its release speaks volumes about a maturing, yet still largely unseen, revolution.
Beyond Air: Why Immersion Cooling is Gaining Traction
For years, immersion cooling – submerging servers in dielectric fluids – was relegated to hyperscale facilities and research labs. The complexity and upfront costs were prohibitive for most. However, the relentless push for higher performance and density, particularly with the advent of PCIe 5.0 and the demands of AI workloads, are changing the equation. Traditional air cooling struggles to effectively remove heat from densely packed racks, leading to throttling and reduced efficiency. Immersion cooling offers a significantly more effective solution, allowing for higher rack densities and reduced energy consumption. As noted in a recent report by 451 Research, liquid cooling adoption is expected to grow exponentially in the next five years, driven by these factors.
QLC NAND and the Capacity Trade-off
Goodram’s DC25F series drive isn’t just about cooling; it’s about capacity. Utilizing QLC (Quad-Level Cell) NAND flash memory allows for significantly higher storage densities compared to TLC (Triple-Level Cell) or SLC (Single-Level Cell) NAND. However, this comes with a trade-off: lower endurance. The drive is rated for 0.3 drive writes per day (DWPD) over five years, making it ideal for cold and warm data tiers – applications where data is accessed less frequently, such as archiving, backup, and large-scale content repositories. This aligns with the typical use cases for ultra-high capacity SSDs.
The Goodram Drive: Specs and Significance
The 122.88TB PCIe 5.0 SSD boasts sequential read speeds of up to 14.6GB/s and write speeds of 3.2GB/s. While these speeds are impressive, they aren’t the primary focus. Random performance, at around 3,000K IOPS for reads and 35K IOPS for writes, confirms this drive is optimized for sequential data access rather than demanding, latency-sensitive applications. The E3.S and E3.L form factors are specifically designed for immersion cooling environments, ensuring compatibility with direct liquid immersion systems. Goodram Enterprise has validated its drives with dielectric fluids from major manufacturers like Shell and Chevron, addressing concerns about long-term material compatibility and electrical degradation.
Beyond Goodram: A Growing Ecosystem
Goodram isn’t alone in exploring immersion and liquid cooling for storage. DapuStor is actively deploying immersion-rated SSDs in telecom infrastructure, and Solidigm is demonstrating liquid-cooled NVMe drives for AI servers using cold plates. Even PC-focused vendors like XPG have experimented with water-cooled PCIe 5.0 SSDs, signaling a broader industry interest. This suggests that immersion cooling isn’t a niche solution but a growing trend with applications across various sectors. The lack of a major marketing push for the Goodram drive is intriguing. It suggests a deliberate strategy focused on direct engagement with enterprise customers and a reliance on technical specifications to speak for themselves.
The Future of Data Center Storage: Density, Efficiency, and Liquid Cooling
The combination of high-capacity QLC NAND, the PCIe 5.0 interface, and the necessity of effective cooling is reshaping the data center landscape. As power densities continue to climb, liquid cooling – and particularly immersion cooling – will become increasingly essential. We can expect to see further innovation in dielectric fluids, drive designs optimized for immersion, and software tools to manage and monitor these systems. The quiet launch of Goodram’s 122.88TB SSD may be a sign of things to come: a future where massive storage capacity and efficient cooling are no longer luxuries, but necessities.
