Biwin M560 Brings DRAM-Less PCIe 5.0 SSDs Closer to Laptop-Ready Performance

As of November 13, 2026, the Biwin M560 stands out because it pushes against the older idea that DRAM-less SSDs are only for budget builds. Tom’s Hardware published its M560 2TB review on November 1, 2026 and gave the drive an Editor’s Choice verdict, describing it as one of the best all-around PCIe 5.0 SSDs it had tested, with strong responsiveness and efficiency. This is still not a full-fat flagship Gen5 drive with onboard DRAM and extreme 14GB/s-class bandwidth, but that is also the point: the M560 is aimed at users who want fast next-generation storage without the heat and power draw usually associated with top-end PCIe 5.0 models.

The Biwin M560 is a PCIe Gen5 x4, NVMe 2.0 SSD in the common M.2 2280 form factor. Biwin lists it in 1TB and 2TB capacities, both with a DRAM-less design, while Tom’s Hardware identifies the tested platform as using the Silicon Motion SMI SM2504XT controller, 218-layer Kioxia BiCS8 TLC NAND, and Host Memory Buffer rather than onboard DRAM. The official specifications put the 2TB model at up to 11,000 MB/s sequential read, 10,000 MB/s sequential write, 1,700K random read IOPS, and 1,700K random write IOPS. The 1TB model is rated for the same 11,000 MB/s reads, but lower 9,700 MB/s writes, 1,400K random read IOPS, and 1,600K random write IOPS. (biwintech.com)

The more interesting part of the M560 is not just its peak speed, but how it handles power. Biwin’s own product page lists average power consumption below 5.2W, while Tom’s Hardware testing found the drive sitting comfortably around 4W in practice, with maximum power draw significantly below 6.5W. That matters for performance laptops, thin workstations, and compact mini PCs where an SSD may sit under a small heat spreader or in a tight slot with limited airflow. A single-sided layout also helps compatibility: Biwin lists dimensions of 80.00 × 22.00 × 2.45 mm and a weight of under 10g, and Tom’s Hardware noted the single-sided build as easier to fit and cool in more systems.

For a primary drive, responsiveness often matters more than chasing the biggest sequential number. Tom’s Hardware highlighted the M560’s low 4KB random read latency and strong application and gaming performance, which are the kinds of traits users tend to feel when opening apps, loading game assets, moving through a busy OS install, or working with project files. The drive’s 2TB configuration is also where the platform appears most balanced: it has the strongest rated random performance in the M560 lineup and an endurance rating of 1,500 TBW, while the 1TB model is listed at 750 TBW. Both capacities carry a 5-year warranty, with the usual limit applying by time or total bytes written, whichever comes first. (biwintech.com)

The M560 is not positioned as the perfect SSD for every build. Biwin’s current official listing shows no 4TB option, which limits its appeal for users who want one large game library, media workspace, or portable editing drive. Tom’s Hardware also found that sustained write behavior changes after the pseudo-SLC cache is exhausted: the 2TB drive used a large cache of around 611GB when empty, wrote very quickly inside that cache, but slowed once it had to fold data back into TLC. For most laptop and gaming use, that is unlikely to be a constant issue, but users who regularly dump huge files or write hundreds of gigabytes at a time should understand the behavior before choosing it as a workstation scratch drive.

The Biwin M560 is useful to watch because it suggests PCIe 5.0 storage is moving beyond hot, premium desktop-only drives. Its combination of a DRAM-less HMB design, modern TLC NAND, high rated IOPS, and relatively low power draw makes it especially relevant for high-performance laptops and small PCs where thermals matter as much as benchmark charts. It is not a review verdict here, and it is not a universal recommendation, but as a product overview the M560 looks like one of the clearer examples of how DRAM-less Gen5 SSDs are becoming more practical for real mobile hardware in late 2026.
