Transcend JetFlash 890 32GB Grijs

De Transcend JetFlash 890s is behoorlijk snel in het random lezen van 4K blokken, het willekeurig schrijven van 4K blokken valt nog te verbeteren.

Pluspunten

  • levensduur lange (gelimiteerde) garantie
  • type-C aansluiting
  • 3,99 gram
  • gemaakt in Taiwan

Minpunten

  • zonder beschermkap voor de USB type-A aansluiting
