2x 15k 300GB SAS Cheetahs

Okay, so I've got two screaming fast 15,000 RPM Seagate Cheetah drives. I'm looking for a SAS controller to let me setup RAID 0, and install Vista x64 🙂

What controller do you guys suggest? I need nothing else from this controller, all my data is on a NAS.

Also, how much of a difference should I feel compared to my old Samsung SP2504C 250GB SATA drive?

Thoughts?

The SAS drives are quick. I went from 2x 7200.10 750GB Seagates to 4x Fujitsu 36GB 10k (2.5") drives. Not that much faster on burst but sustained was about 60MB/s faster. As for the RAID controller, anything from Areca is good. I'm a huge fan of Adaptec but some of their cards can get pricey. Here are some that I found are good:
PCI-E x8
PCI-X. I think this one uses your SAS ports on the motherboard to send/receive data.
 
Hmm. I understand that a good SAS controller is expensive. BTW, I'm probably putting this in the second PCIe x16 slot in of my P35 board - how are those electrically wired? x4 IIRC.

How much would I lose by dropping down to something like this:

It doesn't have a hardware controller or any cache RAM, but I'm sort of under the impression that those are only really necessary for RAID5, or other more complex configurations.

If need be I will spring for a nice controller, but how much performance improvement am I looking at?

The hardware cache and XOR help regardless of the configuration. It's dumb vs. intelligent storage hosts. When UW SCSI was hot a lot of geeks were putting 4.3GB UW SCSI drives on a 2940UW and wondering why they weren't any better than a UDMA drive. Well the controller makes all the difference in the world!
