And what is actually even more visible to the user are the strange
buffer size constraints: Only the whole memory can be used, thus
nperiods*fragmentsize*samplesize is fixed. Each of those parameters has
only few possible values. For typical settings (32Bit/sample and ADAT
mode) this results in fragment sizes of either 64 or 256 samples (thanks
to the jack developers now at least nperiods can be decreased to values
below the hardware nperiods, though). Synchronizing and hardware routing
is much less flexible than with later RME products.

Personally I would avoid that card (I bought an RME Digi96/8 a few years
ago, everything said here holds for the whole Digi96/8 series).
