Greg,
I replied to your e-mail even before you posted here & addressed each of your questions. The S2VRHD was discontinued because many people were asking for a RAID 5 protected product, so we've now replaced the S2VRHD with the CalDigit RAID card along with the HDElement.

If your ports are all used up on your FASTA card, you would need to get a 2nd card (If you have a spare expansion slot).
