==Tips==
The X1011 currently does not support all RAID types, including RAID 1 and ZFS. This might be due to driver compatibility issues, which are yet to be confirmed and advised. The X1011 is a collection of four M.2 SSD drives recognized as separate drives by the OS. It uses the ASM1184e PCI express packet switch, with 1 PCIe x1 Gen2 upstream port to 4 PCIe x1 Gen2 downstream ports, enabling users to extend PCIe ports on a Raspberry Pi 5.
To verify whether it is a hardware problem:
1. Clear any RAID settings and mount each drive as a separate volume.
2. Open a second terminal to Monitor for any NVMe errors (I/O timeout, reset controller, I/O error, etc.):
pi@raspberrypi ~ $ sudo dmesg -w | grep -i nvme
3. Create a 30GB testing file on one of the SSDs:
pi@raspberrypi ~ $ sudo dd if=/dev/zero of=./TestingFile bs=100M count=300 oflag=direct
4. Copy the 30GB file to multiple SSDs simultaneously:
pi@raspberrypi ~ $ echo /media/pi/cn600/ /media/pi/spcc/ /media/pi/netac/ | xargs -n 1 cp ./TestingFile
