The drive specified is a Hitachi HUA (Hitachi Ultra Star) floppy drive. This is an expensive, enterprise-rated drive. There is a very similar part with the HDS (Hitachi Desk Star) prefix. Ultra Star is designed for 24/7 server usage. Desk Star (HDS722020ALA330) is designed for desktop use with far fewer hours per year. If you pay for HUA, make sure you get it.
