KingSpec NVMe SSD Drive
After reviewing the NanoPC-T4 SBC (Single board computer) with a basic configuration with 16GB eMMC internal storage, I decided to test it with a 256GB NVMe SSD card purchased on AliExpress. Adding such a card is an excellent solution for users needing extra storage space, especially if you plan to install additional software packages that occupy more space. In this test, I installed a 256GB Card in the T4 M.2 PCIe socket/slot on the back side of the T4 Board and ran some performance checks. Having said that, for more detailed information, you are welcome to check the links posted below:

KingSpec NVMe NE-256 Package
KingSpec NVMe Pkg 1
Package Content
The package came with KingSpec NVMe NE-256 Card, and a small Philips-type screw used to mount to a PCB. In this case, the screw didn’t fit the thread on the NanoPC-T4 thread, so I used a larger one.

How to Install
Assembling the NE-256 SSD card is very easy. You need to open the bottom cover of the case, Spot the PCIe socket and genteelly insert it into the socket and finally tighten it using the screw and the built-in thread located on the NanoPC-T4 Board. After accomplishing this step, you must format the SSD Card so the OS will recognize it. You can create and format the partition in CLI (Command line) mode, which is the less user-friendly method, or use ‘GNOME Disks‘ tools that come with a graphical front-end GUI, used for partitioning, monitoring, and benchmarking that makes the task of preparing and formatting partitions a lot simple.
If, for some reason, the disk management tool is not included in your Linux distribution. To install ‘Gnome Disks‘ software package under any Debian / Ubuntu-based distribution, you will need to execute the following commands:
$ sudo apt-get update $ sudo apt-get install gnome-disk-utility
After the process is done, you can find the tool under ‘Settings -> Disks.’
Testing & Benchmark
For the test, I installed the Armbian Bionic Linux distribution, specially designed for ARM Boards, along with the NE-256 formatted to NTFS.
READ benchmark (Average value)
$ hdparm -t /dev/nvme0n1 /dev/nvme0n1: Timing buffered disk reads: 2032 MB in 3.00 seconds = 676.95 MB/sec

Benchmark Settings:
For measuring the read/ write transfer rate, I have set the number of Samples to 100 with a sample size of 1GB running 1000 samples to get a proper reading about how this flash drive performs.
Gnome Disks Test Results:
According to the NE-256 specifications, the flash memory can reach up to 2400MB/s with a Write Max speed of Up to 1700mb/s. In real-world tests, according to my trials, the read transfer rate reached a peak of 1.3 GB/s, while in the reading tests slightly below 1.0 GB/s. Overall, pretty good results for a $40 NVMe SSD Card.
