Wiretrustee SATA is a Raspberry Pi Compute Module 4 (CM4) carrier board for DIY network attached storage (NAS). It is the first such board to directly transfer data via the native CM4 PCIe interface, and thus avoids unstable USB-to-SATA connections.
Wiretrustee SATA features four SATA ports, one gigabit Ethernet port, and a small form factor (100 x 100 mm), making it possible to build a tiny home NAS. It supports 2.5" and 3.5" drives, both SDDs and HDDs. Whereas 2.5" drives can be plugged in directly, 3.5" drives require additional extension cables.
In addition to a fully assembled and tested board, we plan to offer DIY kits for building your own complete NAS.
Wiretrustee SATA supports all the Compute Module 4 variants thanks to a microSD card slot (for CM4 light) and a firmware flashing mode via the top-side USB 2.0 port (for CM4 with eMMC).
Wiretrustee SATA board has been verified to work with Raspberry Pi OS with SATA drivers enabled in a cross-compiled kernel. All the necessary installation instructions and scripts (including RAID setup), as well as board schematics and PCB layout, will be published on our website.
"I've built a few Raspberry Pi NASes in my day, but none were *this* nice."
"Wiretrustee has designed an ultra-compact x4 SATA Raspberry Pi CM4 carrier board with up to 220MB/s throughput for NAS applications."
"The good news is the board is now open-source hardware with all resources shared publicly including the Allegro schematics and PCB layout, Gerber files, 3D models for the heatsink, and case designs for 2.5-inch or 3.5-inch drives. "
"The NAS-oriented SATA Board supports any Raspberry Pi CM4 variant. The carrier provides a Marvell 88SE9215 controller to enable 4x powered SATA ports with up to 220MB/s throughput."
