^I'm really sorry to hear of your DVD problems in Paraguay.
Since reseating my ram, my DVD burner & disks work perfectly.
But if I could afford to trade my mid-tower pc and DVD burner & disks for a mini-pc setup with 4-8GB ram and whatever peripherals I needed, I do believe I would be tempted to make the switch.
For a basic noninclusive list of mini-pc peripherals, I would need 3 duplicate HDs and cloning unit, 2 thumb drives, and I think I would actually try for an external DVD burner anyways.
Also to be able to plug in my vintage 286 key-click keyboard.
My DVD backup burning activities typically come in the 5MB to 10MB range, rarely 20MB or 30MB or more.
edit: Come to think of it, generically speaking, a DVD and a thumb drive are both 'removable media' with 'no moving parts'; so a set of 2, 3, or 4 identical large capacity, high data-rate transfer thumb drives would make a suitable upgrade/replacement for DVD disks.
To avoid virus hits or other hazards, the thumb drives would need to normally only be plugged in just long enough to write or read the backup data, and be unplugged all the rest of the time.
