About the KCMYXRUG1T92
KCMYXRUG1T92 is Kioxia's flagship enterprise 1.92TB read-intensive PCIe Gen5 x4 NVMe solid state drive in the CM7-R series. Engineered in a 2.5-inch 15mm U.3 form factor, it leverages Kioxia BiCS FLASH TLC NAND to achieve sequential read speeds up to 14,000 MB/s and random read throughput of 2,200,000 IOPS. It sits at the pinnacle of modern enterprise flash, doubling the throughput of previous PCIe 4.0 drives for real-time machine learning inference, trading systems, and high-performance databases.
Compatibility
The drive requires server backplanes and host adapters wired for PCIe Gen5 NVMe (such as Dell PowerEdge 16G, HPE Gen11/Gen12, Lenovo ThinkSystem V3). It operates via standard U.3 interfaces and supports single-port Gen5 x4 or dual-port Gen5 x2/x2 operation. It is backward compatible with PCIe Gen4 backplanes, operating at Gen4 bandwidth. It will not function in SAS/SATA backplanes lacking PCIe routing.
How to identify a genuine unit
The drive features a silver 15mm aluminum casing with a Kioxia enterprise label displaying model KCMYXRUG1T92, CM7-R 1.92TB, and PCIe 5.0 / NVMe notation. In Linux, nvme list identifies the drive as KCMYXRUG1T92. In OEM systems (like HPE P63829-B21), it may carry vendor-customized firmware and vendor label overlays.
Buying used
Verify remaining write endurance and available spare blocks using nvme smart-log. Because Gen5 drives operate with high transfer rates, verify that thermal pads and enclosure fins are undamaged to ensure proper chassis airflow cooling. Ensure the drive caddy provided matches your server chassis generation.
