About two and half years ago, I collected the prices of various storage media, and calculated the cost per GB. Since then, there have been big movements, and as expected the storage continue to get cheaper and cheaper. With the 2 GB disks, the price is 4 Euro cents per GB.
Optical storage also gets cheaper, and in recent years bigger spindles of Blu-ray disk have been made available. They are still beaten by DVD-R, however the margin is no longer significant. Two years ago, it was three times more expensive to store on Blu-ray than DVD-R. Also interesting is the DVD DL 8.5 GB prices. They are now almost as expensive to use as DVD 4.7 GB. That might be interesting for backing up bigger files.
New to the list is the Solid State Disks. At 40x Euros / GB, they are still very expensive compared to spinning disks, but given some time, maybe it might drop. However, looking at the professional CF Cards, it does not look promising for solid state. Although the get faster and bigger, high end Sandisk CF cards have not move significantly in terms Euro / GB. Of course, there are slower chips which are cheaper, but you might not want that technology in your SSD.
