SSD KIOXIA CD8-R 2.5", PCIe 4.0, 112-layer BiCS FLASH 3D TLC, up to 6600MB/s - KCD8XRUG15T3

This SSD KIOXIA CD8-R is a 2.5" PCIe 4.0 NVMe drive aimed at server/workstation environments where IOPS, reliability, and consistent latency are more important than flashy marketing numbers. You get up to 6600MB/s read speed and up to 6000MB/s write speed, plus high random IOPS values, which is critical for virtualization, databases, and intensive backend workloads. It uses BiCS FLASH TLC memory and supports NVMe 1.4, positioning it as a serious enterprise solution, not just a „faster drive“ for desktops. The form factor is 2.5", but with a PCIe NVMe interface, making it suitable for server platforms with U.2/U.3 slots and backplanes.

What you get

With up to 1050K IOPS random read and 195K IOPS random write, you can expect serious throughput under multiple simultaneous requests – a typical scenario for virtual machines, containers, and transactional systems. The drive is rated for 1 DWPD (Drive Writes Per Day), meaning it is designed for regular and heavy rewriting every day, without worrying that you will „wear it out“ in a year or two. Power loss protection (PLP) is crucial for servers – in case of sudden power loss, buffered data in the cache is „finished“ to NAND, instead of leaving the file system in an undefined state. End-to-end data correction and SIE security add another layer of security and data integrity, which is important for sensitive information or regulatory requirements. The high MTBF of 2,500,000 hours and 60-month warranty support the idea that this is a long-term solution for production environments.

• Drive type SSD from the CD8-R series, specifically designed for server/workstation workloads where stability and predictable performance are critical.
• Interface PCIe NVMe 4.0 with support for NVMe 1.4, providing significantly lower latency and higher parallelism compared to SATA solutions.
• Form factor 2.5" with dimensions 100.45 x 69.85 x 15 mm and weight 130 g, suitable for server platforms with U.2/U.3 slots and backplanes.
• Read speed up to 6600MB/s and write speed up to 6000MB/s, allowing for quick loading of large data arrays, backups, and recovery operations.
• Random performance up to 1050K IOPS (read) and 195K IOPS (write), optimal for virtualization, databases, and many parallel requests to the storage layer.
• Memory type BiCS FLASH TLC with a rating of 1 DWPD, balancing between capacity, endurance, and price for daily heavy write workloads.
• Reliability with MTBF 2,500,000 hours, Power loss protection (PLP), End-to-end data correction, and SIE security for data protection and integrity in an enterprise environment.
• Long warranty of 60 months, supporting its positioning as a long-term investment for production systems.

Who it is suitable for

This KIOXIA CD8-R is aimed at admins and integrators who are building or upgrading server/workstation systems – virtualization hosts, databases, storage for applications with many random operations. It is also suitable for heavier workstation configurations where there is significant I/O load (DevOps, analytics, backend services). If you are looking for a cheap SSD for a home desktop or gaming, this is probably overkill and you won't utilize its full potential.

The strongest aspect here is the combination of PCIe 4.0 NVMe performance, enterprise features like PLP and end-to-end data correction, and a rating of 1 DWPD, making this drive a very stable foundation for serious server/workstation projects.
