Important Notes

• Never connect both a DC adapter and an ATX power supply to the board at the same time. Doing so will permanently damage the board and any connected devices.
• Do not power your Raspberry Pi5 through its USB-C port while using this board. Use the X1017 as the sole power source for your Pi.
• Use a stable 12V power supply within the specified range. Over-voltage will damage your hard drives.
• The X1017 is designed for data storage purposes and does not currently support booting from HDD/SSD with the existing firmware.
• Auto Power Cut-off (for drives): This feature works only when powered via the DC jack. It is not available when using the ATX 4-pin connector.
• All SATA ports share the Pi 5's PCIe Gen3 x1 total bandwidth. No impact on HDDs; only affects multi-SSD full-load scenarios.

Overview

The X1017 is a PCIe 3.0 to 8-port SATA expansion board designed specifically for the Raspberry Pi 5, providing a one-stop solution for high-capacity, high-speed storage upgrades.

It addresses two major pain points in building multi-disk storage systems with the Raspberry Pi 5:

• Insufficient native storage capacity:

Supports simultaneous connection of up to 8 SATA hard drives, with a maximum capacity of 22TB per drive and a total capacity of up to 176TB.

• Confusing power supply for multiple hard drives:

Equipped with dual 12V power input options (two standard DC power jacks and one 4-pin ATX power connector), One single power supply powers both the Raspberry Pi 5 and all connected SATA drives — no separate Raspberry Pi power supply needed. High-power setups (e.g. 8×3.5" HDDs) require dual DC adapters; see technical specs for details.

Supports simultaneous access to multiple hard drives and features 8 SATA 3.0 interface with bandwidth up to 5Gbps, ensuring fast and stable data transfer. Suitable for building home media centers, personal NAS, closed-circuit television video storage, and personal data backup servers.

Features

• 8 x SATA 3.0 Ports ： Connect up to eight SATA devices simultaneously to your Raspberry Pi 5
• High-Capacity Storage ： Up to 176TB theoretical total (22TB per drive; compatibility varies)
• Wide Drive Compatibility ： Works with all SATA 6G, 3G, and 1.5G hard drives and SSDs
• Multi-Speed Support ： Supports communication speeds of 5.0, 3.0, and 1.5 Gbit/s
• HDD/SSD status LED: flashing: Solid light for device connected, flashing for read/write activity, off for no device connected.
• Flexible Power Input ： Accepts 12V power via DC jack or ATX 4-pin connector
• Unified Power Delivery ： High-efficiency DC/DC converter delivers up to 12A to power both Pi 5 and SATA drives from a single source
• Pogo Pin Power to Pi 5 ： Powers your Raspberry Pi 5 directly via pogo pins; no separate power supply needed
• Automatic Drive Power Cut-off ： Cuts power to SATA devices when Pi 5 shuts down (DC jack only; not supported with ATX 4-pin)
• Splitter Cable Included ： Comes with a power SATA splitter cable to support up to 8 drives
• HAT-Friendly Design ： Mounts on the bottom of the Pi 5, allowing use of standard HATs with no protruding components on the bottom
• 12V PWM Fan Header： For custom case cooling solutions
• Tested and supported operating systems: Raspberry Pi OS (64-bit), OpenMediaVault (OMV)
• Compatible Accessories: PA12V10A power adapter, X15-F10 8010 PWM-controlled fan

Note:

• The X1017 does not support SATA boot with the current Raspberry Pi5 firmware.
• The X1017 powers the Raspberry Pi 5 via pogo pins. Do not power the Raspberry Pi 5 through its USB-C port
