DW1670 from Meritline

Hi

I’m thinking about buying the DW1670 from Meritline ($38). No one else seems to be selling it yet. Is this for real?

If so, should I even buy this drive? A lot of people seem to think the 1650s are a lot better. Is this still common thought?

I’m mainly concerned with longevity and compatibility.

Thanks!
