So far we've mostly seen this PCIe interface used for M.2 expansion slots on devices ranging from industrial computers to carrier board such as Piunora or Gumstix Raspberry Pi CM4 development board. But Wiretrustee had a different idea and designed carrier board with Marvell 88SE9215 PCIe to SATA controller and offering four SATA connectors to build a 4-bay NAS with Raspberry Pi CM4 module. Wiretrustee SATA board Raspberry Pi Compute Module 4 Wiretrustee carrier board specifications: * Supported SoM - Raspberry Pi Compute Module 4 and 4 Lite * Storage + 4x SATA 2.0 via Marvell 88SE9215 (PCIe 2.0 x1 to 4 6Gb/s SATA ports, no HW RAID) chip tested at a write speed of ~220MB/s on each of the SATA ports (not simultaneously) + MicroSD card slot * Video Output - HDMI 2.0 up to 4Kp60 * Networking - 1x Gigabit Ethernet port * USB - 2x USB 2.0 ports * Misc - 4-pin fan, RTC + battery, external control board connected via FPC cable with more LEDs, reset and power buttons. * Power Supply - 5V via USB-C port up to 5A max, or 12V/5A via 4-pin header * Dimensions - 100x100 mm Wiretrustee NAS control boardWiretrustee SATA board and control board Raspberry Pi CM4 NAS Carrier Board Layout 220MB/s for one SATA port at a time may seen relatively slow, and indeed, the developer explains performance was not the goal on Reddit: I'm not chasing high IO therefore a limitation of PCIe x1 wasn't a real problem to me. I still think you could have a decent speed with only one lane especially for my case where I anyway will connect and download/upload files from/to the home network via the internet The initiative actually started as a software project with a goal of developing personal cloud storage + VPN solution, and they started to work on an ODROID board, but with the launch of RPi CM4 decided to build their own board. Raspberry Pi Compute Module 4 NAS Carrier board There's close to no information about the software right now, and the hardware is not available yet, with Wiretrustee planning to launch it via Crowd Supply, and they will make sure it works with both 2.5-inch and 3.5-inch drives. You can still influence design choices on the Reddit thread, and more details may be available on Wiretrustee website. If you'd like a Raspberry Pi 4 based NAS, but are not quite the patient type, there's always ROCK Pi SATA HAT.
