Thanks for doing all that testing! Nice to see that answer pretty much boils down to "Use something decent-ish, mostly it doesn't matter which choice you make".

Thanks for doing all that testing! Nice to see that answer pretty much boils down to "Use something decent-ish, mostly it doesn't matter which choice you make"... (I would have guessed nVME would have been worth spending extra on, turns out not by enough to care about, at least not in a Pi4.)
- geerlingguy 6y agoYeah the Pi 4's USB 3.0 bus isn't able to take advantage of the speeds faster drives can put out; I'm hoping the next compute module can support NVMe or SATA more directly (something Eben Upton hinted at in a podcast earlier this summer). A Pi 4 B+ or Pi 5 could even fit a slot underneath?
- Zenst 6y agoI'd expect the compute flavour to expose the PCIe bus, so SATA or NVMe would be easily added as no USB3 chip hogging it. Indeed I'd say that is not only a given avenue, but the angle Mr Upton was hinting towards given the I/O side of things currently from the SOC. Like many - pre Pi4, was wishing for a SATA port, but overall, if they did do some upgrade to the Pi4 in another B+ or 5 flavour - then I'd be more interested in a faster USB flavour, like 3.2 or USB-C. Reason being is that it would be more flexible and those who want SATA or NVMe would be able to tap into that. Certainly more flexible in usage and that does seem to be key.
- The_Hermit 6y agoYes, I'm also anxiously waiting for the CM4, but wouldn't M.2, NVMe, & etc. be located on the carrier boards, instead of the Computer Module?
