I've got access to a 2 GByte DAT/4mm/DDS (whatever you choose to call it)
and have no problems using an Adaptec 1542. I use a non-compression drive.
Switching on hardware compression can increase the transfer rate by about
the same amount as the compression ratio.
Under DOS (yech!), I can back up about 400 MBytes in just over 15 minutes
using PCTAR. When I get the time to bring up Linux, I hope to get about
the same performance.
I've heard that there are new QIC drives about to go on the market which
are said to outperform both 4mm and 8mm. I'll believe this when I see it!
Personally, I look at 8mm vs. 4mm as about equal, provided you match the
drives feature-for-feature. 3-1/2" half-height for DDS is rather handy.
