StarTech.com 8 Port 6Gbps SATA PCI Express Card Controller

This 8-port SATA III (6Gbps) controller enables you to add eight SATA 6Gbps hard drives (HDDs) or solid State Drives (SSDs) to your computer system or server via an available PCIe x4 card slot. The card supports SATA III and PCI-Express Gen 2 Specifications and four SATA controllers to deliver a high-performance data storage solution.
Quad Controllers to Deliver 8-Port SATA 6Gbps Performance
Featuring four 2-Port SATA 6Gbps controllers and a PCIe-x4 MUX, this SATA card enables the connection of eight high-performance SATA 6Gbps drives with a combined total throughput of up to 16Gbps. The SATA drives are connected via two Mini-SAS ports with two included Mini-SAS to 4x-SATA adapter cables. To ensure a secure connection, each SATA port on the included cables features a locking connector, that will prevent the drive from accidental disconnection when working inside your computer case.
Wide Compatibility
The PCIe MUX that's built into this controller card manages the downstream controllers, which improves motherboard compatibility by ensuring the card will work with motherboards that support bifurcation and motherboards that do not. To further improve motherboard compatibility the card does not have a built-in RAID controller, but fully supports the use of software RAID. Plus, with supports for PCIe Gen 2 and SATA III Specifications this card ensures backward compatibility with previous generations (SATA I/II, PCIe Gen 1) at lower performance.
The controller card is widely supported across all popular operating system platforms including Windows (7,8,10, 11), macOS (10.10 - 11) and Linux (2.6.32 and above).
Hassle-Free Installation
The SATA controller card features plug-and-play installation and can be installed in full-profile and low-profile computer systems with a full-profile bracket preinstalled, and an interchangeable low-profile (half-height) bracket included. The card also supports storage software data management systems such as Storage Spaces (Microsoft) , RAID Assistant (MacOS) and mdraid/mdadm (Linux), for hassle-free setup, partitioning and software RAID array building.
