Hello, @moebear.

Thank you very much for waiting.

More details about this specific model are not available, right now the best option is to contact the vendor who provided the unit, if they can provide you with their  benchmarking results, you can use them to compare your drive; the document I mentioned before can also be used as a reference on how you should prepare the drive and the system before performing the benchmark.

I will proceed to close the thread right now as there are no other recommendations or information we can provide due to the drive being a promotional/special edition and the best option would be to contact the point of sale or vendor for additional information.

If you require any type of assistance in the future, please open a new community thread as this one will no longer be monitored.

Best regards,
