Build a Cheap NAS Server with the NanoPi M4 SATA HAT

FriendlyElec SATA HAT is an add-on expansion card designed to provide SATA interfaces to the NanoPi M4V/2 SBC series. The extension board is powered through the NanoPi M4V/2 header pins. The NanoPi M4V/2 board has four SATA V3.0 interfaces, one power interface, a power button, an onboard fan power interface, two USB interfaces, and a secondary 12V power input interface. With these improvements, you can use a desktop computer PSU to power it.

For those interested in buying this board, the NanoPi M4 SATA HA is currently on sale for $25 on the official FriendlyElec website. This is an inexpensive solution for M4V/2 SBC owners who want to expand their board’s capabilities. They can build their own NAS server device. Then this is a great option worth considering.

The Package

Package Contents

• 1x SATA HAT
• 1x Heatsink + thermal pad + two screws
• 2x SATA cables.
• 4x M2.5 Brass Hex M F Standoff, 4x screws.
• 1x SATA Power cable.

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 for using 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 are also included with the kit. The ideal approach for best cooling is also to buy a big aluminum 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.

SSD Speed Test

• SSD Model: SL700
• Brand: Lenovo
• Capacity: 480GB
• File system: NTFS
• Cache: independent cache
• Size: 2.5 inches
• Interface: SATA3
• Working temperature: 0 – 70 degrees
• Write speed: 540MB/s
• Reading speed: 450MB/s

Step#1 – Checking device storage information

root@nanopim4v2:~# lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda           8:0    1 447.1G  0 disk
└─sda1        8:1    1 447.1G  0 part
mmcblk1     179:0    0  14.5G  0 disk
└─mmcblk1p1 179:1    0  14.3G  0 part /
zram0       252:0    0    50M  0 disk /var/log
zram1       252:1    0     1G  0 disk [SWAP]

Step#2 – Formatting SSD to NTFS File system

sudo mkfs.ntfs

Step#3 – Deactivating Cache

hdparm -W0 /dev/sda

Step#4 – Measuring the READ speed of the SSD device/dev/sda with hdparm

root@nanopim4v2:~# sudo hdparm -Tt /dev/sda

/dev/sda:
 Timing cached reads:   2668 MB in  2.00 seconds = 1334.43 MB/sec
 Timing buffered disk reads: 1092 MB in  3.00 seconds = 363.95 MB/sec

Step#5 – Measuring the READ speed of the SSD device/dev/sda with dd

root@nanopim4v2:/mnt/ssd# sudo dd if=/dev/zero of=/tmp/test1.img bs=1G count=1 oflag=dsync
1+0 records in
1+0 records out
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 2.25947 s, 475 MB/s

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 want to build a small and low-power desktop computer or NAS server, then choosing either of these boards along with the FriendlyElec aluminum Heatsink would be a great option.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.
