Description
The Galileo PES320A is a dedicated PCI-Express expansion card designed to overcome the limitations of modern and legacy motherboards by providing two additional SATA III internal ports. Built on the PCI-E 2.0 specification, this interface card ensures a stable 6.0Gbps bandwidth per port, allowing users to maximize the performance of high-speed Solid State Drives (SSDs) and high-capacity Hard Disk Drives (HDDs). Its compliance with AHCI 1.3 and SATA 3.0 standards ensures seamless integration into existing hardware environments without the bottlenecks associated with older SATA II connections.
This product is for:
- PC Builders: Ideal for enthusiasts who have exhausted the native SATA ports on their motherboards and need to add more internal storage.
- Legacy System Upgraders: Perfect for users with older motherboards that only support SATA II, providing a path to SATA III 6Gbps speeds.
- Home Server Administrators: A cost-effective way to expand drive arrays in NAS or media server builds requiring reliable internal connections.
- IT Professionals: A versatile tool for maintaining older workstations, supporting a wide range of operating systems from Windows XP to Windows 11.
- Data Recovery Specialists: Provides a stable, bootable SATA interface for testing and accessing drives outside of the primary system controller.
Detailed specifications:
- Interface: PCI-Express v2.0 (Compatible with PCI-E 1.0, 2.0, and 3.0 slots).
- Slot Compatibility: Fits into PCI-E 1x, 2x, 4x, 8x, and 16x slots.
- Ports: 2 x Internal SATA Revision 3.0 (6.0Gbps).
- Protocol Support: AHCI Rev 1.3, NCQ (Native Command Queuing), and Port Multiplier.
- Backward Compatibility: Fully supports SATA II (3.0Gbps) and SATA I (1.5Gbps) devices.
- Operating Systems: Windows 11, 10, 8.1, 8, 7, Vista, XP, 2000 (32/64-bit); Windows Server 2008/2003.
Installing the Galileo PES320A is a straightforward process thanks to its plug-and-play nature on modern operating systems. Once seated in a PCI-E slot, the card provides immediate access to two additional SATA channels that support system booting, which is critical for users looking to run an OS from a drive connected to the expansion card. The inclusion of NCQ technology optimizes the order in which read and write commands are executed, resulting in smoother multitasking and improved drive longevity during heavy data workloads.
When compared to standard USB-to-SATA adapters, the PES320A offers superior stability and lower latency by communicating directly over the PCI-Express bus. Unlike integrated motherboard controllers that may share bandwidth with other peripherals, this dedicated card maintains consistent throughput for both connected drives. It serves as a more reliable alternative to port multipliers that rely on a single host port, as it provides two independent channels for uncompressed data transfer speeds.
Q&A:
- Can I install my operating system on a drive connected to this card? Yes, the PES320A supports bootable SATA devices, allowing it to function as a primary boot controller.
- Is this card compatible with a PCI-E x16 graphics card slot? Yes, the card is designed for x1 slots but is physically and electronically compatible with x2, x4, x8, and x16 PCI-E slots.
- Does this card require additional drivers for Windows 10 or 11? Most modern Windows versions will automatically recognize the card using native AHCI drivers, though legacy systems may require manual installation.
- What is the maximum speed I can expect from an SSD? The card supports SATA III speeds up to 600MB/s, though actual performance depends on the SSD's specifications and the PCI-E bus version.
- Does it support Port Multiplier technology? Yes, it supports Port Multiplier, allowing for even further drive expansion when used with compatible hardware enclosures.
