Picture in Figure 1 below shows the Read/Write Benchmark of my M900 Tiny when only the M.2 NVMe THNSN5256GPUK is installed. But when I add a second SATA drive, the Read/Write result falls as low as 147 MB/s and 206 MB/s respectively. Please look at the picture in Figure 2.
The picture in figure 2 is the Read/Write Benchmark of my M900 Tiny when the Toshiba M.2 NVMe THNSN5256GPUK and the Western Digital WDC WD10SPCX 2.5” SSD are installed.
What might be causing the slow down of my M.2 NVMe Drive?
I also tried using the SATA M.2 version SSD and I have no issues when installed together with the 2nd Western Digital drive. But the NVMe M.2 version are really slow when the 2nd Western Digital SATA drive is added

It might be worth monitoring the temperature of the NVMe drive. It might become too hot and start throttling, when run together with the 2.5" SSD drive. There are indications of NVMe drives reaching extremely high temperatures, even when they are the only drive in operation in the M900 Tiny.
