Build an Open Source NAS Server | SATA HAT expansion card for NanoPi M4V2
NanoPi M4 SATA HAT
FriendlyElec SATA HAT is an addon expansion card designed to provide SATA interfaces to the NanoPi M4V/2 SBC series. The extension board powered through the NanoPi M4V/2 header pins. And besides, the four SATA V3.0 interfaces and one power interface FriednlyElec also add few cool improvements such as power button, onboard fan power interface, two USB interfaces, and a secondary 12V power input interface so you can use a desktop computer PSU to power the NanoPi M4V/2 board.
For those interested in buying this board, the NanoPi M4 SATA HA is currently on sale for $25 on the official FriendlyElec website. It’s a very low-cost solution for existing and also new M4V/2 SBC owners interested in expending their board capabilities to the next level by building their own NAS server device. Then this is a great option worth considering.

NanoPi M4 SATA HAT Board
Hardware
The SATA HAT is powered by Marvel 88SE9215-NAA2 chip series that are compliant with Serial ATA Specification 3.0 supporting communication speeds of 6.0 Gbps, 3.0 Gbps, and 1.5 Gbps. The kit includes an aluminum heatsink that sits on top of the Marvel chip to keep it cool under high heavy operation.
Assembling Both Boards
There are two main options to use the SATA HAT expansion card. If you didn’t buy the NanoPi M4/V2 heatsink unit, you could connect both boards using four Hex M F Standoff, and nuts also included with the kit. The ideal approach for best cooling is also to buy the big aluminium heatsink which provides excellent cooling for the CPU.

Power Supply
To power the SATA HAT board along with the NanoPi M4/V2 SBC you would have to buy a power 12V-2A adapter.

Benchmark using GNOME Disks (Read/Write)
In this benchmark/stress test, we selected a 1G file size for the sample and let it run for a few minutes. The SSD was tested under Armbian Focal (desktop) mainline based on kernel 5.4.y. Overall test results were pretty impressive with average reading speeds of 338 Mb/s and write speeds of 401 Mb/s.
Final Verdict
The SATA HAT for NanoPi M4V2 performed externally well. If you are considering building a small low power desktop computer / NAS server, then both boards combining with FriendlyElec aluminium Heatsink would be an excellent pick. An upper cover to close this semi-open case could also be a good idea. Perhaps made of plastic, just to cover the boards entirely and with few slots for adding additional USB ports.
