  • Communication Protocol

    Most SSDs use SATA III or PCI Express.

    Almost all 2.5" SSDs connect via SATA III while most M.2 SSDs connect via PCI Express.


    PCI Express connection offers higher speeds, but this is mainly noticeable in demanding applications (high-resolution video processing, transferring large files, etc.) and is not necessary for everyday use.

  • Write Speed

    Indicative size for the maximum speed of the hard disk during data recording. The larger the size, the faster the data recording.

    For an SSD that uses the SATA III protocol, the average recording speed is 300MB/s, while for one with NVMe it is 1200MB/s.

    These differences make sense in particularly demanding use cases (e.g. high-resolution video editing). For most users, the differences will not be noticeable.

  • Read Speed

    Indicative size for the maximum speed of the hard disk during data reading. The larger the size, the faster the data reading speed.

    An average reading speed for an SSD using the SATA III protocol is 600MB/s, while for one with NVMe it is 2000MB/s.

    These differences make sense in particularly demanding use cases (e.g. high-resolution video editing). For most users, the differences will not be noticeable.

Description

Description

The KIOXIA CD8-R series is an NVMe™ SSD for read-intensive data centers, optimized to support a wide range of scaling and cloud applications, such as big data/IoT, online transaction processing, and virtualization. Built with a PCIe® 4.0 interface (16 GT/s x4), the CD8-R series SSDs deliver consistent performance of up to 1,250K IOPS (random read) and 200K IOPS (random write).

Featuring KIOXIA 112-layer BiCS FLASH™ 3D TLC memory, the 2.5-inch CD8-R SSDs provide 1 DWPD (Drive Writes Per Day) endurance and storage capacity of up to 15.36 TB in a 2.5-inch form factor, making them suitable for hyperscale applications in data centers.

Key Features:

  • Compatible with PCIe® 4.0, NVMe™ 1.4 specifications
  • Support for Open Compute Project Datacenter NVMe™ SSD v2.0 specification (not all requirements)
  • Form factor: 2.5 inches, 15 mm thickness
  • Proprietary KIOXIA architecture: controller, firmware, and BiCS FLASH™ 3D TLC 112 layers
  • Single-port design, optimized for data center class workloads
  • Consistent performance and reliability for demanding 24x7 environments
  • Designed for high-density storage installations
  • Power loss protection (PLP) and end-to-end data correction
  • Security options: SIE, SED

Basic Applications:

  • Hyperscale
  • IoT and big data analytics
  • Online transaction processing (OLTP)
  • Virtual environments
  • Media streaming and content delivery networks

Capacity
7680 GB

Capacity

The golden ratio of cost and capacity for now is 500GB and 1TB.

For gaming or professional programs that require a lot of space for their installation, a capacity of at least 500GB is recommended. 

As an indication, a 1TB hard drive can hold about 250 thousand photos taken with a 12MP camera or 250 movies.

Dimensions

Form Factor
M.2 (Type 2280)

Form Factor

The term form factor refers to the physical size of SSDs. The motherboard must support the form factor of the SSD in order for it to be installed.


The higher speeds offered by an NVMe drive are mainly applicable to demanding applications (such as high-definition video processing, transferring large files, etc.) and are not necessary for everyday use.

M.2 (Type 2280)
The motherboard must support the form factor in order for the SSD to be installed on it. It is worth noting that M.2 drives are divided into those that use the SATA protocol and those that use PCI Express. Of the SSDs that use the PCI Express protocol, most also support NVMe technology, which allows them even faster speeds if supported by the motherboard.

Maximum 4KB Random Write

Indicative size for the maximum speed of the hard disk in data recording during general use, for example (opening the computer/using applications). The larger the size, the faster it is in these functions.

Average read speed for an SSD using the SATA III protocol is 80,000 IOPS, while for one with NVMe it is 380,000 IOPS.

These differences make sense in particularly demanding use (e.g. high-resolution video editing). For most users, the differences will not be noticeable.
