I don’t know if I could call this a review, but I would like to show how they performed.


I bought these two at Kingston costs 700THB (~22.5USD) SanDisk costs 490THB (~15.75USD) considering Kingston was twice the size, I didn’t expect much from it. However, my jaw was dropping and conducting test again and again to see if I was wrong.

I know this is just a sloppy test of how it performed:-

For Kingston one.

root@840evo:~|⇒  dd if=xubuntu-13.04-desktop_armhf_odroidxu_20130917_HDMI.img of=/dev/sdd bs=4M
1410+0 records in
1410+0 records out
5913968640 bytes (5.9 GB) copied, 408.31 s, 14.5 MB/s

SanDisk one.

root@840evo:~|⇒  time dd if=/dev/zero of=/dev/sdd bs=4M
3799+0 records in
3798+0 records out
15931539456 bytes (16 GB) copied, 1520.28 s, 10.5 MB/s
dd if=/dev/zero of=/dev/sdd bs=4M  0.00s user 16.73s system 1% cpu 25:20.28 total

It didn’t matter how large file was, Kingston was definitely better. I had tried many times with wide ranges of files including /dev/zero, results were just the same. I have used the same card reader, Lexar USB3 one, same adapter. Maybe I was wrong. I thought SanDisk was always superior to Kingston, esp. at the same class and pricier.

I hope this help change someone’s mind out there thinking like I did.
