I've made some more tests since then, and I was using cheapo drives for
testing that for some reason, behave extraordinarily poorly in
combination with the LSI card. I've retested the card with hitachi
Ultrastars and it worked just fine (though a bit slower than Adaptec
6xx5). OTOH, the Adaptec works fine with the "bad" drives too, go
figure.
I didn't yet explored the advanced capabilities of the card (apparently
it may have some snapshot mechanism) because MegaCli is such a PITA :)
regards,
