Hardware RAID for the fastest Raspberry Pi CM4 NAS!

Hardware RAID for the fastest Raspberry Pi CM4 NAS!

Finally, with a bit of help from some Broadcom engineers, I got full hardware RAID working on a Raspberry Pi. And I actually used SAS drives this time. Special thanks to Broadcom for sending me a controller card and storage backplane to test on the Pi, and for their...
I lied… WiFi 6 on the Raspberry Pi is NOT faster than Ethernet

I lied… WiFi 6 on the Raspberry Pi is NOT faster than Ethernet

As it turns out, my benchmarking process was flawed, and I had to learn a bit about the Linux networking stack to figure out why! Special thanks to commenter marvell marvell for pointing out the obvious, and to Javier Choclin for suggesting I try out the MZHOU...
PCI Express arrives on the Raspberry Pi CM4 – A Guide

PCI Express arrives on the Raspberry Pi CM4 – A Guide

The Raspberry Pi Compute Module 4 IO Board exposes an x1 PCI Express Gen 2.0 slot. What can you do with the slot? And are there any tips or tricks to make sure you don’t accidentally cook a PCIe card—or the Pi? See all the cards I am testing:...
Raspberry Pi CM4 does 2.5 Gigabit Ethernet!

Raspberry Pi CM4 does 2.5 Gigabit Ethernet!

The CM4 goes beyond 1 Gigabit with WiFi 6. But can it do 2.5 Gbps Ethernet? I’ll explore that question using the Rosewill RC20001 PCIe card, and test how fast it can go on my new baby 10 Gbps home network! Support me on Patreon:...
WiFi 6 on the Raspberry Pi CM4 makes it Fly! MORE THAN 1 Gbps!

WiFi 6 on the Raspberry Pi CM4 makes it Fly! MORE THAN 1 Gbps!

The Raspberry Pi has built in 802.11ac WiFi. But it’s not that fast. Let’s see what we can do about that! I tried getting both an ASUS AC51 and Intel AX200 PCI express card working on the Raspberry Pi Compute Module 4. How did that work out? Check out this...
