The NVMe SSD That Kioxia Quietly Ships to Every Hyperscaler — Now Available to Enterprise Buyers
Kioxia (formerly Toshiba Memory) does not market its enterprise SSDs the way Samsung does. It does not run flashy launch events. It supplies the NAND and controllers that power hyperscaler and OEM storage platforms — which is why the Kioxia CD8P is the drive that many enterprise buyers have never heard of, but every hyperscaler has tested. The CD8P 7.68TB is a PCIe 4.0 x4 NVMe SSD rated at 2 DWPD, built on Kioxia 112-layer BiCS FLASH 3D TLC, with a 1,050K read IOPS and 250K write IOPS profile that positions it between read-intensive (1 DWPD) and write-intensive (3 DWPD) tiers. It is the mixed-use drive for virtualization, قواعد بيانات, and AI training data pipelines.

CD8P vs PM9A3 vs 7450 PRO — The NVMe Mixed-Use Tier
| ميزة | Kioxia CD8P | Samsung PM9A3 | ميكرون 7450 PRO |
|---|---|---|---|
| Endurance | 2 DWPD | 1 DWPD | 1 DWPD |
| Random Read IOPS | 1,050K | 1,000K | 1,000K |
| Random Write IOPS | 250K | 180K | 410K |
| Sequential Write (sustained) | 4,600 ميغابايت/ق | 4,000 ميغابايت/ق | 5,600 ميغابايت/ق (SLC-assisted) |
| NAND Layer Count | 112-layer | 128-layer | 176-layer |
| Best For | Mixed-use, الافتراضية, AI pipelines | General-purpose, read-heavy | Write-heavy mixed workloads |
| Price (relative) | 100 percent | ~90 percent | ~105 percent |
The CD8P’s 2 DWPD endurance is the differentiator: double the PM9A3’s 1 DWPD at a price premium of only ~10 percent. For virtualization clusters where VM write workloads exceed 1 DWPD on active nodes, the CD8P delivers twice the endurance headroom at a fraction of the 3 DWPD tier cost.
