KCD81VUG6T40

High-Performance 2.5in U.2 NVMe Data Center SSD featuring PCIe Gen4 throughput with the KCD81VUG6T40

KCD81VUG6T40 is a 6.4TB Kioxia CD8-V Series data center SSD designed to deliver consistent low-latency storage across PCIe Gen4 NVMe paths in modern 24/7 rack server platforms. By aligning high sequential bandwidth with strong random 4K read capability, KCD81VUG6T40 supports read-intensive database and analytics tiers where predictable service times and queue-depth efficiency matter more than peak burst performance.

Built on 112-layer 3D TLC NAND, KCD81VUG6T40 balances capacity density with sustained endurance rated at 3 DWPD over 5 years, enabling consolidation of boot, data, and hot-read datasets without frequent drive rotation. The 2.5in U.2 form factor integrates cleanly into front-serviceable bays and backplanes, while NVMe over PCIe Gen4 reduces protocol overhead and improves parallelism versus legacy SATA/SAS stacks. Power behavior is engineered for enterprise thermal envelopes with 5W idle and up to 19W active, supporting high-drive-count nodes where airflow and PSU headroom are controlled resources.

Why Choose the KCD81VUG6T40?

KCD81VUG6T40 provides a pragmatic density-to-performance profile for virtualisation and cloud infrastructure boot/data tiers, delivering high IOPS where VM sprawl and metadata-heavy operations can bottleneck shared storage. With power-loss protection, end-to-end data protection, digitally signed firmware, and sanitize/instant erase, KCD81VUG6T40 is suited to scale-out deployments that require auditable lifecycle controls and predictable reliability under mixed read-heavy load.

Kioxia designs the CD8-V series around enterprise validation discipline, emphasizing firmware integrity, steady-state behavior, and compliance-aligned features such as OCP 2.0 management hooks. This engineering approach supports standardized operations in data centers targeting consistent provisioning, secure decommissioning, and long-run service continuity.

Key Applications:

Read-intensive databases
Analytics and search indexes
Virtualisation boot and data tiers
Cloud infrastructure caching
High-IOPS NVMe server storage

At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your storage architecture and rollout schedule, and you can extend the warranty up to 6 years to align the KCD81VUG6T40 with enterprise refresh and support cycles.
