There are currently flash ram drives in internal disk drive form factor, but much more expensive (per byte) than rotating disks. CD, DVD, and I believe Blu-ray, can usually be repolished to get the scratches off. That is, for the ones it can't read through with the error correcting code. It seems to me that if you want to mass produce solid state prerecorded storage, then something like mask ROM would be a better choice than a form of RAM. I haven't followed mask ROM technology lately, though. -- glen

If you can link with a C library, you can try this one : http://mega-nerd.com/libsndfile/ who is very efficient and can read/write a _lot_ of sound files. -- Et pendant ce temps-l�, dans les plaines de Russie...

No storage medium is perfect. Plain old paper has certain advantages for written material. But every time I encounter a DVD player struggling to read a DVD (and it happens more often than you might expect), I think to myself that there has to be a better way. So far, SD cards have been more reliable for me. > There are currently flash ram drives in > internal disk drive form factor, but much more expensive > (per byte) than rotating disks. There usually is a premium to pay for the newest technology. SSD is generally much faster than spinning media. Pundits are currently raving about Intel's X25-E, but even that pales in comparison to what Pliant has. Then again, Pliant's products are vastly more expensive than the Intel X25-E. > CD, DVD, and I believe Blu-ray, can usually be repolished to > get the scratches off.

As long as the polycarbonate isn't thinned too much, considering that it's part of the optical system. > It seems to me that if you want to mass produce solid state > prerecorded storage, then something like mask ROM would be > a better choice than a form of RAM.
