Envoy Express: SSD Compatibility Notes

Created on: February 17, 2021

Relevant Part Number: OWCTB3ENVXP00

For MacSales-purchased enclosures that shipped prior to December 4, 2020, some third party M.2 SSDs may not work properly, even if their specs match the general requirements. Since that time OWC began applying a hardware modification to the enclosure that resolves the compatibility issue for some drives. This is an ongoing effort. For enclosures purchased from resellers (as of January 2021) it is likely you received one that still requires the modification. If either of these scenarios applies to you, please contact OWC Support so that we can assist you.

The table below provides a list of drives known to have compatibility issues, as well as whether the issue was resolved by the hardware update. Information provided based on drive manufacturer and series. Because stability may vary from one part number to the next, we cannot guarantee that the provided fix will work with all capacities within a series. This list will change over time as new SSDs are tested.

We have tested several other brands and series including multiple Samsung 960 and 970 EVO SSDs, as well as models from Toshiba / OCZ, Western Digital, and Corsair. Thus far all have functioned in the Envoy Express without need of the hardware modification. We will add additional brands and models as issues are reported.
