Kioxia’s CM9-R underwent testing at 15.36 TB capacity in E3.S format for x86 and Arm PCIe Gen5 servers.

ServeTheHome published a review of the Kioxia CM9-R 15.36 TB E3.S solid-state drive (SSD). The capacity refers to the individual drive under review, rather than an aggregate server-storage configuration.

The article identifies the product as an NVMe—Non-Volatile Memory Express—SSD and discusses it as an option for x86 and Arm servers using Peripheral Component Interconnect Express (PCIe) Gen5. E3.S identifies its physical form factor, while x86 and Arm identify the server architecture contexts.

ServeTheHome characterizes the drive as fast and a top-tier option for those server platforms. The supplied excerpt contains no numerical throughput, input/output operations per second, latency, endurance, or power measurements, so it does not support a quantified benchmark comparison.
