KIOXIA lists the CM9-R E3.S at 3,400K IOPS random read and 540K IOPS random write. It is E3.S, 7.5 mm thick, and uses PCIe 5.0 with NVMe 2.0. That 15,360 GB model carries the 3,400K IOPS random-read figure. Host link speed is 128 GT/s, with single x4 or dual x2.

Capacity splits the flash generation. Lower SKUs stay on BiCS FLASH generation 5, while larger SKUs carry generation 8. Endurance is 1 DWPD, and the top capacity is 30.72 TB. Dual-port design targets high availability, and OCP Datacenter NVMe SSD v2.5 support is partial.

Constraint is endurance, not read speed. A 1 DWPD drive is built for read-heavy enterprise traffic, not for write-heavy databases that need higher wear tolerance. The page does not prove that every SKU holds the 3,400K IOPS ceiling under mixed load, so a buyer should treat the headline as a peak, not a fleet-wide guarantee. For the fab, the mixed generation 5 and 8 lineup means the SKU line is split by flash generation, not by a single die.

This packet has no figure, and it leaves latency, mixed-load sustained IOPS, and thermal throttling unmeasured in any printed table. Power is listed as 25 W active and 5 W ready, typical, but still no thermal curve or latency curve is shown in the printed packet at all.

A 1 DWPD endurance rating limits the drive to read-heavy roles, and the 3,400K IOPS figure is tied to the 15,360 GB model, not all SKUs. Buyers should not assume mixed-load sustained IOPS or thermal behavior from the sheet.
