Possible Performance Issue if 2 Virtual Disks have different disk speed and size?

I have an MSA 2324fc with 2 Virtual Disk
VDisk1 (10 x 300GB 10k rpm)
VDisk2 (6 x 200GB 10k rpm)

Intended and about to configure a Vdisk3 with 4 x 500GB 7.2K RPM.
Will there be performance degradation on the previously configured Vdisk if I add the 3rd VDisk with 4 x 500GB 7.2K RPM??

No, each vdisk is a different set of disks and is accessed independently. The MSA uses a switched SAS architecture, the packets for each disk do not depend on the packets for others. The SATA vdisk will be slower, but it will have no effect on the other vdisks.
