SCSI U320 15K HD or SAS 15K HD?

[hybrids14]

I just purchased Seagate SAS 73GB ST373454SS 15000RPM 2 units and but also have a Cheetak U320 15K4 ST3146854LC. Which one do you guys prefer? SAS or U320 HD running Raid 0? I just want to have them basically running Windows and have extra SATA HDs for data storage...

I still use 4pcs Seagate U320 15K SCSI HD right now.
I think both products which you owned are all nice stroage media, you can
choose which you like.
