We are currently looking into a company called Q-Systems for an optical drive for our iris 4D/20's. Q-Systems 6701 Democracy Boulevard Suite 300 Bethesda, MD. 20817 Phone: (301)-571-9338 Sales Rep.: Brian Swafford Drive $7500, Disk $250 I cannot remember if these prices are GSA or not, but the Drive is the SONY SMO-S501 Erasable Optical Drive, and the disks are 650Meg (325Meg/side).

Are you sure about them being 650Mb? I think they are less than 600Mb when used with an SGI machine. -- Brent L. Bates NASA-Langley Research Center M.S. 294 Hampton, Virginia 23665-5225 (804) 864-2854 E-mail: blbates@aero4.larc.nasa.gov or blbates@aero2.larc.nasa.gov

The 1024 byte/sector media (which is not filesystem compatible----yet) yields 652 total. If you use the (not yet readily available, I'm to understand) ZCAV media, this will be up lots--like 466/side at 512 byte sectors. I'm not sure if Sony supports this media, but the unit that SGI is considering OEMing certainly will. Our sales people can assist you in contacting one of our Geometry Partners for obtaining WORM, ROM and I think some MO (erasable) 3rd party solutions if you can't wait for the product from SGI (RSN (real soon now)). Don't be too hasty. We expect our device to be quite a bit faster than the products currently available.

You said 1024 bytes/sector is not filesystem compatible----yet! How long until it is? How long until the ZCAV media is available? If Sony doesn't support this media, who else is making the MO drives. As far as I have seen Sony is the only one making them. Buying a drive from SGI at twice the cost everyone else sells it for doesn't sound appeling either. We are looking at buying a MO drive shortly after our 4D/210VGX arrives, which hopefully will only be a few months from now. -- Brent L.

ZCAV is available to me in limited quantity today, but don't know about more commercial availability time frames. MO mfrs. include Sony, Ricoh, Maxoptics, Hitachi, Kodak, and probably others that I am not familiar with. Not too sure about Kodak any more but they and Verbatim (as I recall) had something going a while ago. I can't change the price for you. That's not in my realm. markb -- Mark Bradley "Faster, faster, until the thrill of I/O Subsystems speed overcomes the fear of death."
