[clug] Booting: Debian stable uses grub 1 or 2? recognising LVM's - SSD

I recently installed an SSD (Samsung 840 Pro Series 2.5-Inch 128
SATA_6_0_gb) and am impressed with the performance.
Mint13 root and /home on the ssd (new install; ext4
Grub2 but not in a separate partition
Separate /var,/tmp and /swap on sata;
'noop' scheduler for the ssd;
Browser profiles using profile-sync-daemon on tempfs.
(With a ram of 8GB I've yet to see swap being used)
There is quite a good write up of this with more suggested tactics here:
