Nothing Ultra

Very disappointed with the poor performance seen catastrophic writing. The Crystal Mark test gives only 70-80 MB / s read and just 10-12 at best writing. The test on the site "lesnumerique.com" for the 32GB version gives much higher write performance. - To 52 Mb / s So the key is under warranty exchange mails for 3 weeks with the SanDisk support which want to accept the fact that the product present a big problem - write speed. SANDISK The response is as follows:
playback speeds are up to 100Mb / s (in your case almost 80-82Mb / s) and speeds décriture are not yet published.
This is not a little exaggeration to say that almost two years after launching the product on the market.
Conclusion: do not buy this model because it is roulette and SAV wants to know nothing.
