![]() Operating Systems Available and Compatibility with k8s.These are the pain points I've identified, each of which I will cover in detail in dedicated sections: ![]() What Belies the ShineĪt the point of purchase and over 6 months of usage, I've uncovered many issues that really made me second-guess my purchase. With those specs, I made a trip down to Amicus Sim Lim Tower to snag one from the shelves. While this is still not cutting-edge performance, it's still a significant and welcome improvement, especially for tasks that have high demands for sequential I/O. On top of all those changes, the Raspberry Pi 4B doubled the micro-SD card slot bandwidth from 20MB/s to 40MB/s. This means we can unleash the full potential of the gigabit ethernet port without worrying about performance degradation of the micro-SD card or external drives, and vice-versa. In the Raspberry Pi 4, the ethernet is built directly into the SoC and no longer shares a bottlenecked bus with USB devices. But what I anticipated the most was the long-overdue elimination of the painful USB 2.0 bus bottleneck that plagued all Raspberry Pi models from Zero to 3B+. There were quite a few aspects about the Raspberry Pi 4B 4GB that got me excited: 4GB Memory, Gigabit Ethernet, yada yada. At that point in time I wanted to run a metric-monitoring stack ( Prometheus + Grafana) for the cluster but after reviewing the memory requirements, I quickly realized that not even all the memory on a single Raspberry Pi 3B node was enough (although I'm cognizant that 1GB isn't much in the grander scheme of things).īrowsing around, the most obvious choice was the next model in the Raspberry Pi line that was just released a few weeks earlier then, the Raspberry Pi 4B 4GB. It was February 2020, I was running my self-hosted apps all on the Kraken cluster then. I'm writing this piece purely to share my experiences with both the Raspberry Pi 4B 4GB and the Rock Pi 4A 4GB. Disclaimer: I'm not affiliated with nor sponsored by Radxa/Allnet, the manufacturers of Rock Pi. On this piece, I document my anticipations, disappointments, and epiphanies over the course of 6 months owning the Raspberry Pi 4B. I had owned it for about 6 months before finally letting it go at a significant loss and honestly, that decision was not as hard as I thought. I sold my Raspberry Pi 4B 4GB recently and replaced it with a Rock Pi 4A.
