Re: Micro SD: Speed vs. Size?

The evo and evo+ are the only cards to consider, and they're priced as cheap as any. I ended up returning the 32GB PRO micro SD card, and used a really old 2GB card I had lying around (also had a 128MB card). Out of curiosity I decided to run benchmarks on the two cards (see attached), they both ar...

Re: Partitioning Scheme (SD & HDD)

The class of the SDCard for the /boot partition doesn't matter an iota. The loader in the GPU is the simplest of the simple FAT file readers. Perfect, that is good to know and it means I can use one of the cards I have on hand instead of the one I purchased. Out of curiosity I decided to run benchm...

Re: Power LED on shutdown - Pi3

Just shutdown my Pi 3 for the first time and have the same question about the red and green LED staying illuminated after shutdown?

Is this normal? Not sure I see a definitive answer here?

Thanks.

Re: Partitioning Scheme (SD & HDD)

I currently have my pi3 booting off a 2gb Samsung class 4 sd, with my files on a usb hdd, so yes your card should work fine Good to know, but I'm not sure if my card is even class 4, maybe I should check the read speed. Also, how are you powering your HDD? From the Pi power supply, hard drive enclo...

Re: Partitioning Scheme (SD & HDD)

If the root filesystem is on your HDD you won't need a 16GB SDcard, it's going to hold no more than 56MB of data. Save your money. So I actually ended up buying a 32GB 90MB/s micro SDcard (that I haven't even opened yet), but I also have two spare micro SD cards just lying around from an old BlackB...

Re: Partitioning Scheme (SD & HDD)

I'd give root 16gig, a couple of gig to a swap partition, and the rest to home. The swap partition idea is interesting, I'll have to read up on that. Any reason to use 16GB for root instead of 10GB? But you might find that putting the hard drive on another machine from the one used for the actual d...

Re: Partitioning Scheme (SD & HDD)

What you might consider would be about an 8 to 10GB root partition, another,--say--10GB mounted as /home for general user space, and the rest as a single large partition mounted where you want to store your media files. What about partitioning my SD card (32GB) and using some of its storage for the...

Interesting point about runaway processes, and it does make sense to limit their access to the whole drive.

I should have mentioned this Pi will be used as an OpenELEC media center, and the 1TB drive to store media files, so would the same considerations apply?

I'm in the process of setting up a Pi 3 with a 16GB 90MB/s micro SD card and a 2.5" 1TB HDD. From what I understand there are performance benefits to using the SD card for the boot loader only and moving the root file system to a HDD, but my primary reason for the HDD is increased storage space.

Re: 2.5" HDD Power (Pi 3)

Bear in mind that you've only got a 200mA margin above the peak Pi2B or Pi3B spec for *all* other USB connections. True, the HDD will be using 80% of the 1.2A peak, but would 200mA be enough for something like a USB keyboard and mouse? How small of a margin is 200mA? Do you really need 1TB? Have yo...

Re: Micro SD: Speed vs. Size?

Once you boot to an HDD, the sd card is ignored unless /boot is accessed.. If the SD card is only being used for the boot loader, would it not make sense to go with the fastest card possible and not be concerned about storage capacity?

Yes, eventually.

But would using a faster SD card for the boot loader make a difference in terms of boot speed?
