- However, there is nothing keeping the price of MO drives from dropping.
- They have been pushing the CD-ROM since 1987, when a CD-ROM drive cost
- about $1500+. A Sony SCSI or ESDI MO drive now costs less than $1500.
-
- I spent some time evaluating the Sony MO drives. The models that I fooled
- with used a cartridge that was 300 Meg on each side. For one of my tests,
- I put a UNIX box with the MO drive attached in a burn-in room that was
- somewhere between 40 and 45 degrees C. I left it in there for 2 1/2 weeks.
- During that time I continually ran a read/write disk exerciser diagnostic
- on the MO disk. It read and wrote millions of sectors on the cartridge.
- I never saw a bad sector during that time, and the drive was set up to
- not deallocate bad sectors. I then did a followup to the test by loading
- UNIX on the cartridge and using it as a main root drive for about a month.
- No problems.
