Have had my eyes on this and 960 evo for a few weeks waiting for a better price on the 500gb 2.5" versions and here it is. Not sure if best ever but it is pretty low.
Umart warranty says 12months, in the specs the warranty is 5yrs (back to manufacturer I suppose).
Couldn't see any deals for m.2 versions.
Not sure if correct but when I put a few postcodes in the shipping box it always showed up as $0. So maybe you can score free shipping as well.
$11 to NSW, but can be as high as $16 to other remote locations
