The slump in "Random Write 512KB" is something enigmatic, but he was comprehensible.
Copy a folder with 22x 500MB files on the card in the S3 went with approximately 9,7MB / s. That's OK.
H2testw: Write: 5000MByte in 7:06 = 12MByte / s Check: (! USB2 Card Reader) 5000 MB in 4:29 19MBytes / s
Conclusion: good map: huge capacity, write speed is OK.
Update:
complete data loss after 4 months out of the blue (Map was beginning on the mobile phone, not touched)
Map nowhere readable / formatted.
And at the beginning of the holiday. Maps, Music, Podcasts, Videos away. The course costs stars.
