It is multiplatform, however it is distributed only as source, however some distros do include it (Debian has it).<p><a href="https://fight-flash-fraud.readthedocs.io/en/latest/index.html" rel="nofollow">https://fight-flash-fraud.readthedocs.io/en/latest/index.htm...</a>
I just bought a 1 Tb. 2.5" Crucial BX500 from Amazon, from the Crucial storefront there, for around 50.00. To me it seems to be an amazingly good deal. Maybe just buy from a reputable vendor/manufacturer and don't look for stuff that's too good to be true?
