Installing an SSD in an SAS Mac Pro

I'm going to be upgrading to Snow Leopard this December, and I'd like to take the opportunity to do a clean install. I'm thinking about doing it onto a new SSD, given the potential speed benefits.

A few questions:
1) Is there going to be a big speed bump over my 15K HDDs using SAS by using a high-end SSD like one's from Intel? Important things to me are program load times and file load times.

2) Most SSDs I've seen are SATA -- are there any good SCSI SSDs out there? Or a good way to hook up SATA to my rig? (I'm no expert, but I don't think you can just throw an SATA into an SAS rig)

Thanks!

Mac Pro 8-core, 3.2Ghz, 8GB RAM, with two 300GB 15000RPM SAS drives in Raid 0, Mac OS X (10.5.8), Computer's name is "Caesar"

To use your SAS drives, and depending on how old, there are still solid proven (loud! though) technical reasons to keep using SCSI/SAS. The speed and quiet of SSD though is nice.

You would need a controller of course. And even Apple's gets you into the $700 bracket. Apple Pro RAID controller is SATA or SAS, but not both (or at least that is what I remember from 2007 when it came out).

SSDs are going to need PCIe SATA III (6Gbps) interface soon as the Mac Pro really only has a limited bandwidth shared over the internal ports actually.
