A stepping, in the semiconductor industry, means a revision of one of the integrated circuits - probably the controller chip. Such revisions are usually to correct errors (er - "errata"). Intel publishes errata lists for its CPUs but may not for the SSD controllers. There won't be any functionality difference. Might just be a timing cleanup or some such. I can see that the product SKU changed.

It's also possible that it's a revision to the circuit board - trace change, part change, etc.

What do you mean with "SKU" ? Greetings TommyBoy

SKU means "part number" or "model number", e.g. SSDSA2MH080G201.
