With a \u00d74 configuration (common for M.2), that implies potential reads of **~32,000 MB/s**. ([pcgamer.com](https://www.pcgamer.com/hardware/ssds/almost-a-full-year-after-announcing-it-micron-finally-launches-the-worlds-first-pcie-6-0-ssd-with-up-to-28-gb-s-sequential-read-speeds/?utm_source=openai))  \n- Micron\u2019s 9650 Gen6 SSD, which is now in mass production, clocks in at about **28 GB/s** sequential read\u2014very close to that theoretical maximum. ([wccftech.com](https://wccftech.com/micron-begins-mass-producing-worlds-first-pcie-gen6-ssd-9650-28-gbps-read-speeds/?utm_source=openai))  \n- Demos (prototypes) have also touched ~27 GB/s in read mode with Gen6 equipment. Writes are still behind reads; sustained speeds drop due to thermal and power limits. ([techradar.com](https://www.techradar.com/pro/micron-just-demoed-the-worlds-fastest-ssd-with-pcie-6-x-tech-a-sequential-read-speed-of-27gb-s-and-yes-its-just-a-prototype-for-now?utm_source=openai))  \n\n---\n\n## \ud83d\udd0d What\u2019s Holding Things Back?\n\nEven with theoretical bandwidth high, actual performance depends on multiple factors:\n\n- **Thermals**: M.2 drives get hot. If the SSD throttles, your sustained speed drops. The fastest drives often include heatsinks or require strong airflow.  \n- **Write endurance vs. NAND type**: Drives using TLC (three bits per cell) are faster and more durable than QLC but more expensive. For instance, Micron\u2019s 3610 (QLC) hits ~ 11,000 MB/s reads in a compact format. ([tomshardware.com](https://www.tomshardware.com/pc-components/ssds/micron-announces-3610-ssd-the-industry-first-pcie-5-0-qlc-ssd-available-to-oems-offers-4tb-storage-in-a-compact-single-sided-m-2-2230-offers-11-000-mb-s-and-9-300-mb-s-sequential-read-and-write?utm_source=openai))  \n- **Lane configuration & motherboard support**: An M.2 slot needs PCIe \u00d74 lanes (with the latest version). Older boards might have only Gen3 or Gen4 slots, dropping throughput significantly.  \n- **IOPS & random access**: Sequential speeds are eye-catching, but for lots of small files/random access work, performance is measured in IOPS. Top drives have ~1\u20136 million IOPS depending on use-case. ([wccftech.com](https://wccftech.com/micron-begins-mass-producing-worlds-first-pcie-gen6-ssd-9650-28-gbps-read-speeds/?utm_source=openai))  \n\n---\n\n## \ud83d\udd2e Bottom Line: How Fast Can M.2 Go?\n\n- Today (2026), **~14\u201315 GB/s reads and ~12\u201314 GB/s writes** is the top end for the fastest Gen5 SSDs.  \n- The Gen6 class, like Micron 9650, pushes reads to **~28 GB/s**, about double Gen5, with writes starting to catch up.  \n- With perfect conditions (Gen6 \u00d74, solid cooling, elite controller/NAND), you\u2019re in the ballpark of **30\u201332 GB/s** sequential reads. Writes will lag some behind that.  \n\n---\n\nIf you tell me your use case (gaming, AI training, video editing, etc.) and what your motherboard supports (PCIe Gen version & number of lanes), I can estimate what *you* might realistically get in terms of speed."
