Re: Which SSD to buy for raspberry pi?

Maybe I should report this as a bug but I see there's a closed bug for this controller which says everything works well with USB quirks enabled. It's too bad, it's a nice little package and the SSD is surprisingly fast. The drive is likely OK, if you can find a working adapter. Quirks is a work aro...

Re: Which SSD to buy for raspberry pi?

First thing I did when I encountered problems. It didn't make any difference and it's not needed on the 3B+ which boots from it now. All but one really old JMicron bridge has been OK for me with quirks, was hoping the same for you. Pi4 USB3 has issues though. I originally assumed it was generic Lin...

Re: autostart and minidlna and vncserver

systemd manages most startup and service tasks on current versions of Raspbian.

"service" is and older sysVinit command. Still around for compatibility sake, but your better off not using it. Google/learn about systemd.

Re: Which SSD to buy for raspberry pi?

Unfortunately this won't work in my Pi4, it causes severe instability (stalled booting, locking up the desktop, locking up the USB bus), but it works perfectly in my Pi3B+. I suspect it's the JMicron controller in the enclosure. USB 3.0 support in the Pi4 is new and I'm hoping various bugfixes will...

Re: Why moving to 64bit?

The same no/limited benefit arguments were made for 32 bit, and will be made for the next generation. I agree 64 bit vs 32 bit is irrelevant for most workloads, but some do benefit. Beyond the number of bits are the compiler optimizations that can be enabled leaving older CPU support behind, and is ...

It could be the USB-SATA adapter you are using (although mine is also using an ASMedia controller).not be relevant to Pi4). Unfortunately that doesn't mean much. I've been testing controllers and have three asmedia controllers on my bench now. All with different chip revisions, but report the same ...

Same at my Micro Center. 1GB boards have been almost always in stock. But no 2GB/4GB boards. I managed to grab a 2GB board early on, but I don't think my store has had them back in since.
Both MicroCenters here show 2GB stock today just to prove me wrong.

Re: 5V 3A charger?

As long as it is 5 Volts, it should be OK if the supply is capable of higher amperage.

DO NOT use anything with a higher voltage rating - bad things can happen in that scenario.

Re: NVMe Enclosures

given the Pi can only reach 80% of full USB3.0 speeds It isn't 80%. They're the same. The advertised 5Gbps for USB3.0 is after the 8b/10b encoding so maximum actual throughput is 4Gbps once you remove that. PCIe 2.0 uses 8b/10b encoding as well and the advertised 4Gbps for a x1 link is before encod...

Re: NVMe Enclosures

It's primarily USB3 interference. Could be multiple issues impacting the difference between the two drives. The HDD itself is less noisy than the SDD, enclosure/cable is better shielded than the SDD, the lower HDD throughput isn't generating as much interference, the chip in the SDD adapter is less ...
