While on the topic of drives on Pi's; I did read this post by Jeff Geerling the other day. Might be something worth looking into if you won't benefit from the additional bandwidth and features of NVMe. https://www.jeffgeerling.com/blog/2024/radxas-sata-hat-makes-compact-pi-5-nas Seems somewhat

Hi, You might want to look at the PIMORONI site [1], single and dual NVMe adapters up to 2280 in length. You can boot from the single slot adapters but not the dual as the existing bootstrap code doesn't recognise the packet switcher/multiplexer although I understand this is being worked on. The

Hi Ralph, That was an interesting read. I wasn't up-to-date enough to know about NVMe over fabrics, nor that the Pi 5 can be attached to an NVMe SSD. On Tue, 21 May 2024 17:31:07 +0100, Ralph Corderoy wrote: > The Linux kernel has NVMe support since 5.0; package nvme-cli drives > it. Linux cert

2024-05-21 Thread Ralph Corderoy
Hi, I wrote a private email to a friend. The content may be of interest to some on the list, so here it is. Do you know much about NVMe over PCIe for SSDs? I don't, only having bought SATA SSDs in the past. The Pi 5 has a ×1 PCIe connector, meaning one channel of two twisted pairs to allow a
