I am seeking advice/recommendations for an optical disk storage system to connect to a PC. The disk will be hooked up to a system that will be retrieving atmospheric measurements in real-time, therefore, fast writing speed is a must. I know very little about optical systems, so any information would be helpful. Thanks in advance, kristi skeens kristi@arbs4.larc.nasa.gov

SCSI Magneto-Optical drives typically write around 70k bytes/sec. In order to speed up writes, you have to keep the unused blocks on the disk in the erased state. If you do that, you can suppress the pre-erase pass during writes and will see something around 200K bytes/sec. I doubt any vendor can supply a driver which does what I just described, so you'll probably have to write your own. -Jonathan hue@island.COM
