This is a brand new unopened Sandisk 1TB nvme ssd. Sandisk and Western Digital had a partnership to produce ssd's until a few months ago. Western Digital was the brand they sold under. WD split off to focus on magnetic platter HDD's while Sandisk took over the ssd business and are now producing there own ssd's under the Sandisk name.

This is one of their first solo ssd's and it's dram-less. It carries the same quality as the WD ssd's. This also a gen 4 ssd with top gen 4 specs as well. I haven't even opened it. It's in the retail packaging.
