The following advises against using low-quality SSDs and M2 for write-back operations and primary disk usage due to reliability concerns.

  • Avoid employing low-quality or inexpensive SSDs for write-back operations as well as primary disk usage, as they are often less reliable and can lead to client hang-ups if the SSD experiences corruption. Furthermore, refrain from using SSDs for specific roles, as this might compromise overall system performance. Opt for high-quality SSDs with superior read/write speeds.
  • Faster SSDs utilized for write-back operations significantly enhance client performance. It is recommended to choose SSDs or NVMe drives with high IOPS (Input/Output Operations Per Second) for random read/write functions exceeding 90,000, such as the Samsung EVO series, to ensure better performance and reliability.
  • M.2 SSDs also provide better overall system responsiveness, especially in scenarios involving multiple simultaneous read/write requests. By integrating M.2 SSDs with high IOPS, such as the Samsung EVO series, you enhance the system's ability to manage large workloads efficiently, thereby improving reliability and reducing the chances of SSD-related corruption.
  • Limited Server PCIe Ports: Server PCIe ports are often limited, so external PCIe extensions or add-on cards may be required to accommodate additional M.2 SSDs.

  • BIOS Compatibility: To ensure proper support for M.2 ports, you may need to upgrade your BIOS to the latest version. This is crucial for achieving optimal performance and compatibility with your M.2 SSDs.
