SSD is a 128GB from sansdisk.
I'm really puzzled.
Did you try running iperf3?
I decided to format the disk and change the "format".
Previously, it was in NTFS, I didn't remember the fact that it was an old laptop disk. I was sure that I alreayd tried it with my bananapi (and so, that it was formated in EXT4).
I formated it in BTRFS and now, speed are at last, OK (no more limit at 25MB/s like the result with a reclen of 4)
40-50MB/s with an old 500GB 2"5 disk, I need to test again the Sandisk SSD. I'll do it later.
You did right the info might be on the Armbian forum but with NTFS how its mounted and the tune2fs parameters make a huge difference.
I can not remember the exact details but a google NTFS-3G tune2fs should help.
Some guru should post a test specification and setup script so we are all singing from the same hymn sheet.

Sure someone will supply the optimal settings
