i got a dvd ram drive recently that i think is really cool; basically it allows me to have unlimited external hard drive space.
Reason i got this is because my 300GB drive crashed on me so i lost all of my data
I heard most hard drives last only a few years because their size makes them unstable; hard drives made a loooong time ago that were much much smaller are a lot more reliable than the huge hard drives of today.
dvd ram uses special dvds that act like hard drive discs; so you can copy and paste & delete in windows explorer - its just a lot slower to transfer the files and each disc is only like 4-9GB depending on if you get single or double sided discs.
the dvd ram discs come in a neat special cartridge that you insert into the drive - that way they wont ever get scratched. According to my brother this is better data security than a RAID system.
its too bad this system is unpopular or it would be cheaper; costs quite a pretty penny for the drive; and the discs arent that cheap either, but i figure its worth it since id just end up losing all of my data again if i bought another hard drive.
