ZuluSCSI Wide supports Ultra Wide synchronous and asynchronous SCSI transfers, with read speeds up to 33 megabytes/second. A sufficiently-fast SD card and SCSI controller with Wide or Ultra Wide SCSI support is required to achieve maximum throughput.
ZuluSCSI is easy to use: Simply place an appropriately named disk image or CD-ROM ISO on your SD card in order to present it for use by your SCSI host system. ZuluSCSI can emulate up to 7 SCSI devices simultaneously at any time, and supports both FAT and ExFAT-formatted SD cards.
Documentation for ZuluSCSI Wide is available here.

All mounting solutions designed for SCSI2SD V5.1/V5.2/V6 work just as well with ZuluSCSI Wide.
