Re: USB to m.2 on pi 4

I don't see much negative stuff here.. :D The USB attached storage numbers for the RPi4 are decent and the best part of it, you don't even need a (more expensive) NVMe SSD, a 'normal' USB-SATA bridge will do it. Whereas I thought (and still think) such SATA SSD setups for all previous RPi models to ...

Re: USB to m.2 on pi 4

To get higher 10Gbps speeds you would need an NVMe SSD and a USB 3.1 Gen 2 NVMe enclosure (expensive) and, of course, you'd need a USB 3.1 Gen 2 device to plug it into. The whole chain (drive, enclosure, cable and device) all have to support the faster standard. Or you opt for an SBC which just off...

Re: Not all RPI 4's are equal?

There are a couple of issues here. The first is, that by the very nature of things, chips vary some from one to the next. The factory tests them to meet basic requirements (will it run at the specified clock speed? do all functions work correctly? can you read and write all the cache? stuff like th...

Re: /boot not on FAT for RPi4

I don't think so. We would have to write a bootloader to recognise EXT4 as well as the current formats, and I don't think there will be enough space in the EEPROM. I vaguely remember someone talking about it, and the engineer who writes the bootloaders making a very strange face. thanks for the fas...

/boot not on FAT for RPi4

With the recent changes, e.g. boot binary yet on SPI flash, do we have a chance to get the new RPi booted from ext4 directly? For those want to argue about pro and con of such an approach, I'm not interested in this discussion. ;)

There is no such thing really. When it comes to supporting interfaces and standards, chances are that it will be supported by Apple for much longer than the competition.

Most often two USB ports are only used to connect a keyboard and a mouse anyway. Ah!

As I could not find an interface called PICE I assume you meant PCIe which is an interface on an X86 pc.
