All we need is USB 3 and it would be perfect.
- Skunkleton 11y agoI am curious of your application for USB 3? Care to elaborate?

- cowmix 11y agoI could use it as a very cheap file server for my home / small office. Also, USB 3 can drive video at pretty fast rates too (for multimonitor setups).
- 2bitencryption 11y agoOn the Pi 2, the ethernet port was really a USB-to-ethernet port plugged into a hidden USB port. So network speeds were limited to USB 2 speeds. I'm guessing the Pi 3 also works like this, instead of having pure onboard ethernet? But I don't know yet.
- khedoros 11y agoIf it's using the same bcm2836 chip, then I think it'll have the same limitations. The markings on the chip in the pictures aren't quite legible enough to me, playing around in a photo editor, but it's marked the same way that the Pi2's chip is, from what I could see.
- morganvachon 11y ago> So network speeds were limited to USB 2 speeds Given that USB 2.0 is 480Mb/s, and Ethernet is 100Mb/s, there is no bottleneck when using the Pi's Ethernet port. I really wish this myth that "Pi Ethernet is slower than dialup because USB" would just die. Of course, like everyone else I'd love to see a new version of the Pi with Gigabit Ethernet directly connected to the system bus, and USB 3.0 while we're at it. But that would greatly increase the cost of the device and also require a newer SoC that supports such things.

- duskwuff 11y agoNone of them. The SD card connects directly to the CPU.
- Relys 11y agoWe can still dream can't we? I hope to see this in the future.
- random55643 11y agoI just want a 64bit one. I put in an order for a Pine 64.
- rasz_pl 11y agopee 3 will be 64bit :)
- random55643 11y agoWhat's a Pee 3? :)
- rasz_pl 11y agoor one PCIe line. Something, anything to get fast I/O.
- ThatPlayer 11y agoI also want USB slave/device/OTG. I've been running a BeagleBoneBlack which does have it.
- pjc50 11y agoPi Zero has OTG, but only one USB port total.
- BHSPitMonkey 11y agoYep! Here's some resources for anyone curious: [1] http://blog.gbaman.info/?p=699 http://blog.gbaman.info/?p=699 [2] https://learn.adafruit.com/turning-your-raspberry-pi-zero-into-a-usb-gadget/overview https://learn.adafruit.com/turning-your-raspberry-pi-zero-in...
- khedoros 11y agoAs I understand it, the port that USB is implemented on for the Pi machines is actually meant as an OTG port, made to act as a host by the drivers. On models with more than one USB port, there's a hub+ethernet chip. On the single-USB boards, they can actually be configured to act as OTG devices. The whole situation means that OTG is unavailable on most models, models that have it only get one USB port (so OTG/host is an either-or proposition), and for the multi-USB+ethernet models, performance over those interfaces is worse than you'd expect (if I remember, BBB gets several times the transfer over USB and network, all at lower CPU usage, right?)
