@DGSRV,

Welcome to our HP User Forum!

I don't see why it wouldn't work, but my question is: why do you need this SATA storage controller card anyway?

The description of this card is as follows:

"SIIG's SATA II-150 PCI controller card is an ideal solution in expanding your SATA storage capacity to your desktop computer. It is designed to add two internal SATA channels for connecting up to two additional SATA hard disk drives. The SATA II-150 PCI controller delivers data transfer rates of up to 1.5 Gb/s, breaks the 137GB barrier to support hard disk drives larger than 137GB. It features independent 256-byte FIFOs per channel for host reads and writes, Native Command Queuing (NCQ) and SATA TCQ commands, and onboard bus master engine to relieve system processor from book keeping effectively enhancing system performance. The SATA II-150 PCI is compliant with PCI Specification, Revision 2.3 and Serial ATA 1.0 Specifications and complement of SATA II optional features, FCC Class B (DoC) & CE regulatory approved and RoHS-compliant. It is also fully compatible with a wide variety of Windows operating systems and is backed by SIIG's limited lifetime warranty."

Thing is, your HP EliteDesk 800 G1 Tower comes with no less than five SATA data ports, and you could use the PCIe 2.0 x16 (wired x4) slot as an additional storage site using an "M.2 NVMe to PCIe 3.0 x4 Adapter" such as this one: Amazon.com: M.2 NVME to PCIe 3.0 x4 Adapter with Aluminum Heatsink Solution : Electronics.

As a matter of fact, even though your HP EliteDesk 800 G1 Tower does not have an M.2 NVMe SSD slot, you can achieve much faster SSD I/O speeds using an PCIe M.2 NVMe SSD adapter card compared with the aforementioned SATA data ports.  As a matter of fact, if you were to opt in, make it your primary (boot) drive.

So, my point is -you have plenty of data connections to add multiple 4+TB storage devices in your Tower AND you have the physical space to comfortably accommodate these storage devices, why need a SATA storage controller card?
