Cisco M.2 SSD Interfaces

cisco-m.2-ssd-interfaces.jpgCisco M.2 Solid State Drive (SSD) interfaces can be either SATA or NVMe.

  • SATA M.2 SSDs use the Serial Advanced Technology Attachment (SATA) interface, which is a mature and widely supported interface. SATA M.2 SSDs are typically less expensive than NVMe M.2 SSDs, but they also offer lower performance.
  • NVMe M.2 SSDs use the Non-Volatile Memory Express (NVMe) interface, which is a newer and faster interface. NVMe M.2 SSDs offer significantly higher performance than SATA M.2 SSDs, but they are also more expensive.

The type of M.2 SSD interface that you choose will depend on your specific needs. If you need high performance, then you should choose an NVMe M.2 SSD. If you are on a budget, then you can choose a SATA M.2 SSD.

Here is a table that summarizes the key differences between SATA M.2 SSDs and NVMe M.2 SSDs:

Feature SATA M.2 SSD NVMe M.2 SSD
Interface SATA NVMe
Performance Lower Higher
Cost Lower Higher
Support Widely supported Less widely supported
Here are some examples of Cisco servers that support M.2 SSDs:
  • Cisco UCS C210 M2 server
  • Cisco UCS C240 M4 server
  • Cisco Catalyst 9500 Series switches

To find out more about the specific M.2 SSD interfaces that are supported by a particular Cisco server, you can consult the server's documentation.
