Solid and with great ratio bang/EUR, like most stuff from Intenso. I needed cheapest SD card, and this one was just a few EURos above cheapest 2/4GB models. 8GB and Class10 transfer speed can come handy
I bought two of these for personal data and not for example photography etc, so I wasn't all that concerned for read/write performance. Since I use them on linux and don't care about the Win compatibility, I format them under f2fs fileystem and not VFAT ( Microsoft). F2FS is optimized towards FLASH based media and amongst other things it levels wear&tear across the memory media, so I can't tell you how it would behave with default format.
just for fun I timed 1GB linear read from the card.
"dd if=/dev/sdf of=/dev/null bs=16M count=64 conv=fsync"
gives me 18+ MB/s read transfer speed.
I didn't try benchmarking direct write because I have valuable data on the key, so I wrote to the file on the f2fs filesystem:
"dd if=/dev/zero of=/run/media/my user name/MY KEY NAME/trala test.bin bs=16M count=64 conv=fsync
It just writes 16 blocks of 64M each to the file ( 1GB in total).
That took cca 168 secs and measured write speed was 6.4MB/s
Note that is lower than 10MB/s as you would expect from Class10, but this might have been due to F2FS peculiarities.
All in all, I'm satisfied.
One star less is because I suspect write speed is indeed a bit lower than Class10 would suggest.
