Raid-5 performance question?

[dvd_maniac]

I have the Promise sx4060 with 4x400GB /133 drives. I started having serious write problems after trying to resize the partition with Partition Magic and Partition Expert, so instead of trying to fix it (OS & programs re-install) I decided to pick up the 3ware 9500s-8 Sata raid card and 4x300GB Sata drives.

Now from what I am reading this is true hardware where the 4060 was not?

So what kind of speed inprovements can I expect from this new card? Giving that both cards are going through the same PCI 2.2 interface was I already maxed out with the slower Promise card?

if you're using SATA, it already improve the overall performance speed (read and write)

and if enable RAID-5, you will even get better read performance and a little better write performance, however you need to waste 300 GB for Parity Bit...I think...(I never install any RAID-5 system before, so this might be wrong)
