I don't trust any magnetic drive technology as back-up. Had a bad experience with Syquest drives years back and I want SECURITY, not the cheapest option. But I don't want EXPENSIVE either. Don't want SLOW (Tape Drives), and I am rapidly outgrowing regular 650 MB CD's. Don't want to wait for DVD-RW to SORT OUT all its stupid standards bickering and incompatibility, either (Could still take them a long time and I need a solution NOW)... DVD-RAM made by Panasonic, Hitachi (big, reliable Japanese manufacturers) looks the best. Lots of professionals say its good, media is widely available, several manufacturers supporting a COMMON STANDARD. I can always go on to the the "Next Big Thing" later on anyway...
