    • Usb or Cf

      Hi what do you guys recommend is the better one to use a usb flash drive or a compact flash card?

      I currently use the DMM supplied 2Gb usb stick plugged in the internal usb slot of my 8000, i use this with a 256mb swap and some picons.

      Would i see better performance if i use a cf card and if so what is a good card to buy?

      Thanks.

      (chmod 755)
      start it from self made /etc/rc3.d/S90UserInit

      3. # MartiniB #
      4. #
      6. `mount| grep -q /media/cf` && exit
      8. for i in /autofs/*-*-*-*-*; do FoundCF="$i"; done
      10. #[ -d "$FoundCF" ] && DevSD=`mount| grep " on $FoundCF "| awk {'print $1'}` && [ -e "$DevSD" ] && echo "$DevSD /media/cf auto defaults 0 0">>/etc/fstab && mount -a
      11. [ -d "$FoundCF" ] && DevSD=`mount| grep " on $FoundCF "| awk {'print $1'}` && [ -e "$DevSD" ] && mount -o rw "$DevSD" /media/cf

      and second script copying files from /media/cf to hdd or network path only at day-time or when space is low
      /usr/script/move_recordings_from_CF.sh
      (chmod 755)
      starting it every hour from /cron/tabs/root

    • CF works longer without any problems.
      USB memorysticks can give problems after some months/years. (bad clusters symptoms)

      But that's what i experience. I use since a few years Compact Flash for timeshifting + picons + backup.
      Harddisk is only in use for recordings + playing.
