Confirmed on Ubuntu 12.10. lshw/udev truncates product model at 16 chars
and firmware version at 4 chars.

$ sudo lshw -C disk | egrep "product|serial|version"
       product: INTEL SSDSA2CW08
       version: 4PC1
       serial: BTPR146100P1080BGN

$ cat /sys/block/sda/device/model 
INTEL SSDSA2CW08

$ cat /sys/block/sda/device/rev 
4PC1

$ sudo hdparm -I /dev/sda | egrep "Number|Revision"
        Model Number:       INTEL SSDSA2CW080G3                     
        Serial Number:      BTPR146100P1080BGN  
        Firmware Revision:  4PC10362

hdparm seems to be correct when printing Model as a 40 char string,
Serial as a 20 char string, and Firmware as an 8 char string.
