Thank you Mark-Jan for the additional information. I’ll study it and compare
with my system. Much appreciated.
Best regards,
Joe

Hi Joe,
With sudo lspci -vvv you will see the capabilties, including the low-level
PCIe bus speed and link count negotiation of the devices. The sudo is needed
to get the low-level LnkCap and LnkCtl bits:

My apologies, I meant to say “Mark-Jan”!

Hi Mark,
I am intrigued by your response and have obtained a tree view for my system as
you suggested to Paul. I’m unfamiliar with the tree view and don’t understand
how to check the number of PCIe lanes that are available to the disk controller
and disks and how to check how many PCIe bridge
Hi Paul,
Thanks for your post. I am new to USRP devices and UHD and GNURadio but I have
recently obtained an X310 with dual TwinRX daughterboards to do pulsar radio
astronomy and I have been exploring exactly the issue you raise in order to
help me with my requirements to record data for hou
Hi Paul,
I can record from the X310 to disk to nvme x4 PCIe at 800 MB/sec
for a few minutes. There is still a risk of O 's appearing.
First thing to check is the number of PCIe lanes available to the disk
controller and disks, and how many and which PCIe bridges are in between
on your motherboar
Hi,
I'm trying to record the full X310 bandwidth, for a few hours, without
any missed samples. Which of course is a bit of a challenge - does
anyone here already achieve this?
We're using a TwinRX, so initially I wanted to record 2x 100MS/s (from
both channels), which amounts to 800MB/s, 6.4
