These are not available with retail support so if you manage to acquire one (which may have been pulled from service with an unknown level of previous wear) you will get ZERO support from Samsung no matter what goes wrong.
well i bought from digitec here in switzerland and they take care of warranty. other than that i don't expect any support from any ssd vendor.
I rely on the physical store i buy from where i live. that's the reason i only buy either physically or from amazon germnay (their support had been rock solid in the last 10 years i had been using them).
