Sata disk performance
For SATA disks it could be usefull to tune your disk a bit for large reads. If your disk is mounted as sda (as you can see if you enter 'mount' in a terminal you can change it as:
echo "1024" > /sys/block/sda/queue/max_sectors_kb echo "512" > /sys/block/sda/queue/read_ahead_kb
