1. Start with interface support
Check the host documentation to establish SATA or PCIe/NVMe support. M.2 names a physical format; connector appearance alone does not establish interface compatibility.
2. Record the installation envelope
For M.2, record the supported length, mounting position, keying and surrounding clearance. For 2.5-inch drives, check the bay, thickness, connectors and mounting provisions.
3. Include thermal and service access
State whether a heatsink is permitted and whether adjacent components restrict the device. Confirm the conditions under which the product will run and how it can be accessed for replacement.
4. Ask for a fit check with the sample
Use the intended chassis or board for evaluation. Keep photographs and host identification with the test result. Final compatibility should follow the host documentation and actual proposed SKU.
