Raid0 or Raid5 for network to disk backup (Gigabit)?

Anyone have any thoughts on this PCIe card, motherboard combo with
this server rack:

Server rack device: Supermicro 2U SC825TQ-560LP (only supports low
profile cards)

with this:

Motherboard: Asus DSBV-Dhttp://www.atacom.com/program/print_html_new.cgi?cart_id=6788940_70_8...
(PCIe x8)

and this for the storage controller:

Low profile 3ware PCIex4: 9650SE-8LPMLhttp://www.ewiz.com/detail.php?p=3WA965SE8&c=fr&pid=a4789c3fafc59a0a8...

I cant seem to find PCIe x8 controller boards to match the max speed
of the motherboard recommended for this server rack device.

WIll these 3 give me the best speed for the money (keeping costs
down). I'll be backing up data across the network, most likely using
Acronis or ShadowProtect with 50gb file splits (as this gave me 4 hour
backup times on a similar server for 332GB vs across network backup
times of 8hr 20 minutes with BackupExec 11d, where acronis over the
network with 50gb splits took 4hr 40 minutes at most!)

As a side note.. the CPU will be woodcrest 2.0 5130 with 2GB of ddr2
667mhz ram.
The harddrives will be SATAII in a 2.2TB array (5 drives of 500gb
each)..http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=101923&pr...
Seagate ES ST3500630NS type drives (does the ES really make a
difference for an org with about 40 users, but most not using the
backup server, it will just backup 5 other server's data, or can I use
regular Seagate 500gb drives to save a few bucks)?

Thanks

EDIT: actually I'm not sure if this motherboard will work with the
supermicro, I may have to go with this one instead, which they
recommended:

I've now decided on this ram, 4gb instead of 2gb
