: Authentic drives typically have a serial number engraved on the metal connector. Fakes may use a single "G" instead of "GB" for capacity.
: Purchase directly from stores like Walmart , Best Buy , B&H Photo , or Newegg .
If a deal looks too good to be true, it is. A 2TB flash drive for $15 is always a scam; legitimate high-capacity drives (1TB+) generally cost over $80.
: Look for poor printing quality, spelling errors, or packaging that isn't heat-sealed plastic (which usually requires scissors to open).
