I'd definitely choose the HP1533A !

It is some three times faster than the Conner,
i.e. does 514KB/s (times compression factor).

Doing backups, I see some 800KB/s to 1100KB/s
written to tape (depending on whether the data
had been compressible or mostly compressed
archives).

Regarding DDS-2: I've heard multiple times,
that DDS-2 tapes are not reliable. And since
somebody had recorded nuclear physics data
on DDS-2 tapes and had found no way to read 
back more than a few MB, I tried myself and
now would never again trust 120m DDS-2 tapes.

Backups to /dev/null are nearly as good, and 
much cheaper (media cost) and faster :-)

} Is this configuration ok for FreeBSD 2.1-STABLE ?

Guess it is Ok. Does the Miro come with a 
fast RAMDAC (175MHz or 200MHz) and a 24bit
CLUT ?

My 20SD seems to have only a 135 RAMDAC (didn't 
check the chip, but there is a large difference
between my 1280x1024 X terminal and the 20SD 
driving the same 19" monitor: The X terminal
offers much sharper vertical lines and an 
overall better picture quality).

It offers only a 6 bits RGB CLUT, i.e. there 
is no difference at all between #808080 and 
#838383 ...

This is of course only important, if those
systems are meant to be used as workstations.
