ZuluSCSI Overview

ZuluSCSI is a solid-state direct replacement for a physical SCSI drive. Since it doesn't rely on mechanical media, it's an excellent choice for retro computers.

Based on my own informal benchmarking, I’ve found ZuluSCSI to be sufficiently fast for older computers. In side-by-side comparisons with real SCSI-2 hard disks, there’s little difference in real-world performance.  ZuluSCSI RP2040 supports read speeds up to 10Mbytes/second and write speeds up to 6Mbytes/second.

An added benefit of ZuluSCSI is that disk images are stored as regular files on an exFAT-formatted SD card. This makes it easy to back up images on a traditional computer and even share them.

Another advantage is that a single ZuluSCSI board can host multiple SCSI targets. This means you can load a CD image of an OS installation CD and a blank disk image to install the OS onto, without needing a physical CD-ROM drive.

ZuluSCSI boards are reasonably priced and have proven to be very stable.

On my Sun computers I place the Zulu board in the Floppy Bay. This allows me access to the card to backup the machine and add disk and CD Images.
