According to Wccftech, Corsair has launched two new PCIe 5.0 SSDs that push storage performance to new heights. The flagship MP700 PRO XT delivers up to 14,900 MB/s sequential read speeds and 14,500 MB/s write speeds, outperforming Team Group’s previous claims by offering superior write performance. The second model, the MP700 MICRO SSD, uses a compact M.2 2242 form factor ideal for laptops and gaming handhelds, offering 10,000 MB/s read and 8,000 MB/s write speeds. Both drives support Microsoft DirectStorage for improved gaming performance and come with Corsair’s SSD Toolbox software for maintenance tasks. The MP700 PRO XT will be available in 1TB, 2TB, and 4TB capacities with a 5-year warranty, with additional capacity options planned for early 2026. This represents another leap forward in the ongoing storage speed race.

The Unspoken Thermal Challenge
While Corsair touts power efficiency, the reality of PCIe 5.0 SSDs is that thermal management becomes exponentially more challenging at these speeds. Previous generation PCIe 4.0 drives already required substantial heatsinks, but PCIe 5.0 drives can generate enough heat to throttle performance within seconds under sustained loads. The MP700 PRO XT’s claimed speeds are likely achieved under ideal cooling conditions that most consumer systems struggle to maintain. This creates a significant gap between laboratory benchmarks and real-world gaming or creative workloads where sustained performance matters most.
Shifting Storage Market Dynamics
Corsair’s aggressive push into high-performance storage reflects a broader industry trend where SSD manufacturers are competing on speed rather than just capacity. As Corsair Gaming expands beyond its traditional peripheral and cooling focus, these storage products represent strategic diversification into higher-margin components. The timing is particularly interesting given that most current gaming systems and even many high-end PCs lack native PCIe 5.0 motherboard support, making this somewhat of a forward-looking product that anticipates wider platform adoption over the next 12-18 months.
Beyond Benchmark Numbers
The practical benefits of reaching nearly 15,000 MB/s read speeds deserve critical examination. For most gaming and productivity applications, the difference between 7,000 MB/s (current PCIe 4.0 speeds) and 14,900 MB/s may be imperceptible to users. The real advantage comes with DirectStorage implementation, where faster data transfer rates between storage and GPU can significantly reduce game loading times. However, widespread game developer adoption of DirectStorage remains limited, creating a “chicken and egg” scenario where hardware capabilities outpace software optimization.
The Cooling Arms Race
Corsair’s entry into the extreme performance SSD market intensifies competition not just on speed specifications, but on thermal solutions. The company’s experience in cooling technology through its case and cooler divisions gives it a potential advantage in designing effective heatsink solutions. However, the compact form factor of the MP700 MICRO presents particular challenges for sustained performance in space-constrained devices like gaming handhelds, where thermal headroom is severely limited compared to desktop systems.
Storage Evolution and Consumer Impact
Looking toward 2026 when Corsair plans additional capacity options, we’re likely to see PCIe 5.0 become the new mainstream standard, much like PCIe 4.0 displaced PCIe 3.0. The rapid progression in storage speeds echoes historical computing advances where each generation brought exponential performance gains. However, consumers should approach these extreme speed claims with realistic expectations about thermal requirements and actual application benefits, as the law of diminishing returns begins to apply to storage performance for typical use cases.
