SATA RAID: 3ware vs. Promise

[Ireneusz Pluta]

Hello group,

I am completing a box for PostgreSQL server on FreeBSD. Selecting a RAID controller I decided to go 
with 3ware SE9650-16, following good opinions about 3ware controllers found on FreeBSD and 
PostgreSQL groups.

However my dealer suggest me to not to go with 3ware, and take Promise SuperTrak EX16350, instead. 
This suggestion does not have any technical background and it comes generally from the fact of 
limited availability of 16x 3ware controllers on the local market and immediate availability of Promise.

Is this technically a good idea to take Promise instead of 3ware or rather I definitely should 
insist on 3ware and wait for it?

Thank you
