RAID controller #2757 & #2780

 Hello All:

Currently, I had a i520 with #0959 populated with 15K 35G disk using #2757.
We need to add in more disks in #0595.

1. Is there is significant difference between #2757 & #2780, especially in
terms of performance in a RAID environment?

2. If I'm currently using #2757 RAID controller card with RAID protection
and have existing data in it, can I upgrade/change it to a #2780 without
having to perform a reload, or lost of data?

3. The eConfig will alway force a #5580 instead of a #2780 in a RAID
configuration, can I just use #2780 alone in a RAID environment without the
auxiliary write cache?

Digitally Yours,
IGS Ang
