I just put a 5445Z in my new server but considering I just got it turned
on about 2 hours ago I really can't say much about it. I have several
Adaptec cards with BBU and the Adaptec people talked me into trying the
new Z version. It's a bit more expensive on the front end but
supposedly you don't have to replace batteries. If you do go with the
new Z version the first thing you'll have to figure out is where to put
it. I was wondering what the zip ties were for when I opened the
package then realized it's to secure the unit to wherever you want in
the chassis. Kinda handy in a way but can also be a pain.
