V7 Nano USB 2.0 32GB Zwart Review

+2
cj1 30 december 2016, laatste update op 13 januari 2017, 257 views

V7 Nano USB 2.0 32GB Zwart

Een erg lichte nano USB stick, die zich sequentieel redelijk snel laat beschrijven en lezen. Random schrijven is erg traag tot heel erg traag. Er zijn weinig slim fit USB flash drives die random schrijven nog slechter doen.

Pluspunten

  • licht: 1,57 gram
  • 5 jaar garantie

Minpunten

  • aluminium huis + kunststof greep
  • <= 1,0 IOPS random write 4K
  • 256K random schrijven is traag: 0.47 MB/sec
  • 500 mA declared power
  • onhandig uitnemen (weinig grip)
