Hello Todd, I sent your question to my tech support engineers at Ecrix. Here is some
information that might help.

Frank,

We have tested both VXA-1 drives, single ended narrow and LVD.  With the Mac
G3 you have to run the VXA-1 LVD on an LVD SCSI controller.  The VXA-1 LVD
will not work on a single ended narrow SCSI controller in a Mac system.  We
did see a faster throughput with the LVD controller card and the VXA-1 LVD,
about 50 to 100 Meg/Minute faster.  This was using an AdvanSys ASB3940U2W
for the LVD vs. an Adaptec Power Domain 2930.  We were doing local backups.
Connected to a network the backups will be slower, even on a 100 Mbps
network.  The LVD should run faster then the single ended VXA-1 but it still
depends on how fast the network can send data to the tape drive.
