Almost 2 000 000 tickets here (total), mysql DB is about 120GB, two rotational 
SATA disks in raid1 array.

For normal usage it works fast. The number of tickets is only a problem for 
searching. Here we still use sphinx and searching is quite slow.

The other problem is that any action like searching blocks rt user session 
totally. So single user can't, for example, view other tickets in second 
browser tab while his search is in progress. That's major pain if you do a lot 
of searching.

Going to try mysql builtin fulltext next (that won't fix session problem but 
has potential to be faster).

Also for big mysql DB you need to plan backup well.

IMO SSD is not required. Obviously will be much faster than rotational disks 
but our instance works well without ssd disks.
