+2
cj1 13 januari 2017, 147 views

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
