We're developing a high speed data acquisition system in our lab based around networked IBM PC-AT's (hey, they're cheap). I'm looking into ways to archive our data, and WORM disks strike me as the best choice (right now). Can any of you kind people out there tell me anything about WORM disks? Like, amount of storage, price, transfer rates on write and read, reliable models, etc.? Also, if you think there are better alternatives, by all means let me know. The amount of data we'll need to store during a study will be on the order of tens of megabytes.

We are using these drives for data archival and the beauty if their scheme is that they have software drivers that allow the disc to be used EXACTLY like a regular DOS disk. Logical drives, subdirectories loads .EXEs from a DOS prompt, etc. This is one of the major faults of Optical disk technology - their use is not transparent to the OS. All you have to do is load a device driver in the config.sys and off you go, the next available drive is the CD-WORM, and you treat it just like any drive. Their access times are better than 65ms, which is great for optical media, and they have a new generation out that has like 18ms times! Great stuff.
