Dear friends,
I tested the performance of 7 different models of
Compact Flash
Cards. I made 2 tests : First I used an USB reader
connect to my pc
to untar my kernel 2.6.21 compressed image (180mb).
Second I booted
the card on my TS7200 board and copied a 32mb file
from one folder to
another.
First :
debian:~# ls -l /d3/b/img-prod-20-08-2008.tar.gz
-rw-r--r-- 1 root root 181593562 2008-08-20 15:43
/d3/b/img-prod-20-
08-2008.tar.gz
mount /dev/sdf1 /mnt/sd
date > copiacf.log
cd /mnt/sd
tar zxvf /d3/b/img-prod-20-08-2008.tar.gz
cd
umount /mnt/sd
date >> copiacf.log
Second :
-rw-r--r-- 1 root root 33554432 Aug 26 09:02

I tested and retested all cards getting almost same
times. As you can
see the difference is huge between the cards.
Dane-elec takes 1:50 to
copy 32mb and Kingston
2gb takes up to 31:25.
Does anyone know a faster CF card ?
We will need to work with TS7260 and SD cards. I
already ordered a
Sandisk Ultra II 1gb and 2gb, Daneelec 1gb and 2gb,
Kingston 2gb.
Does anyone recommend a fast SD card model ?
Regards,
Fabio.
