Urk!
Where is this documented? And - is it something you can do nothing
about, or are we ultimately trying to address it somewhere / somehow?
Thanks!!

As a followup, the system I'm trying to use this on is a dual PII 400

2 500 GB drives with 2 120 GB in a RAIDZ. The idea is that I can get
2 more 500 GB drives later to get full capacity. I tested going from
a 20GB to a 120GB and that worked well.
I'm finding the throughput just isn't there. < 2MB/s compared to
20MB/s on a similar Linux system.
Anyone else going this low budget?
There are many folks (including myself) that have done similar super-low
budget setups. Which SATA controller are you using? If it's the
SI3112, it has a documented problem when you try to use both SATA
channels simultaneously - it gets less than 2MB/s, compared to about
50MB/s on each drive individually. I'm not sure if the SI3114 has
similar problems, or not. This may not be your problem, but I know the
SI3112 was popular on machines in that timeframe.
