hp ciss on freebsd

Hi.

We are using a HP DL 380 G5 with 4 sas-disks at 10K rpm. The
controller is a built in ciss-controller with 256 MB battery-backed
cache. It is partitioned as raid 1+0.

Our queries are mainly selects.

I will get four 72 GB sas-disks at 15K rpm. Reading the archives
suggest raid 1+0 for optimal read/write performance, but with a solid
raid-controller raid 5 will also perform very well when reading.

Is the ciss-controller found in HP-servers a "better" raid-controller
compared to the areca-raid-controller mentioned on this list?
