Hello Seitz
Thank you for your inquiry. We currently do not have a product that can support 5 HDDs that connects via USB or eSATA. The closest products we have would be the MB174U3S-4SB (https://www.icydock.com/goods.php?id=191) and the MB561U3S-4S R1 (https://www.icydock.com/goods.php?id=218). Both of these products supports 4 HDDs and connects via USB or eSATA.
If you have any questions on our products, feel free to send us a message.
