Experience of LSI MegaRAID 9260CV?

Hi,

I'm fairly familiar with the 3ware range of SATA RAID controllers
and their particular quirks. I'm finding them harder to get hold of
however, and I've now repeatedly run into the situation where my
suppliers are pushing LSI MegaRAID instead.

Have any of you transitioned from 3Ware to LSI and how have you
found it?

Particularly the 9260CV controller is being suggested to me instead
of the 3ware 9250SE-8LP. This appears to have a large capacitor
instead of a Li-Ion battery in order to achieve its battery backup.
Anyone got any experience with that?

Cheers,
Andy
