Raspberry Pi releases faster class A2 micro SD cards and bumper case for Pi 5

The news item on the Raspberry Pi web site has more technical details about the work on the SD card driver that was necessary to get fast command queueing woking https://www.raspberrypi.com/news/sd-cards-and-bumper/

Oh nice! I follow sites like cnx software for embedded news but had missed this CQHCI/Command Queueing Host Controller Interface. I've been wondering when we might see

Is this the first cqhci driver in Linux? Man, back when sata got ncq and USB got UAT which both help with queuing it was such a huge help. I've wondered what the state of SD cards is, what might have changed or be changing. There have been some interesting really small nvme attempts, some with just a bunch of extra contacts on the cards - but this seems like an interesting offering!

I hope it or something else like it spreads! We are leaving performance on the table. And I really really dig the small size of micro-sd!! Also huge shout out to RPi for testing resilience by power cycles during heavy use. RPi is definitely going to raise the bar & others are going to have to improve (testing/reviewers will too), with this leap. So excellent.

The bumper seems nice.

I've gone SSD on my Raspberry PI and not looking back, but I guess for student applications, the SD Cards are nice: https://x.com/benhouston3d/status/1749255041842647499

Last night I was wondering if any small ARM SBCs could max out a gigabit Ethernet connection when transferring files from their USB/microSD storage. Perhaps this will be possible now with Raspberry Pi's new microSD cards?

Is there any benchmarks for the SD Card speeds now? Last time I promised a high end SD Card I got around 95MB/s on my Raspberry Pi. What is the theoretical max speed now?

I really just want a few sata ports on these things now. Would be nice if you could build a budget NAS with one of these. Only realistic game in town is N100 based systems.

There are a ton of Raspberry PI hats with SATA ports. It is basically a whole sub-industry. Here is one example: https://www.jeffgeerling.com/blog/2024/radxas-sata-hat-makes...

Are Pi’s viable as Roku type devices? (Jellyfin/Plex @4k, streaming and local playback)

Not quite in my experience. You can pick up an N100 based computer on amazon for $100-$150 that works really well though.

Thanks.

I've been hoping for something like the bumper case for a while now. Awesome to see.

Haha I don't understand these. I just bought a refurbished PC with 16GB ram for $40.

Raspberry pi zero 2w makes sense for things like turning your old printer wireless but these other expensive pis don't make sense to me at all

Well the raspberry pi original/primary use case is to be a development platform.

That it could also be used as a cheap small server is just a testament to the versatility of rpi.

Now that Windows and Mac computers both ship with ARM CPUs, it may become convenient to have an ARM server at home for self-hosting and small development. Not having to cross compile docker images for x86_64 saves time.
