I’ve been using it for a number of years now. I like that it lets me exercise my programming and math skills over the typical mouse driven graphical CAD UI. It’s also part of the FOSS tool chain I’ve been using for my 3D printer since 2012. OpenSCAD → Slic3r → Marlin on an open hardware design.

I've uploaded a video how you can install Debian Buster to SATA storage on ODROID-HC4, basically it's about Petitboot. Please note that the way how to install Ubuntu 20.04 using Netboot Installer is same, I just picked up Debian Buster in the video to promote it.

Awesome feature for the upcoming HC4.
Has support for Logitech Unifying Dongle been implemented yet?.

The Wiki said to use
  • ubuntu-20.04-4.9-minimal-odroid-c4-20201015.img.xz
but there is also
  • ubuntu-20.04-4.9-minimal-odroid-c4-hc4-20201015.img.xz
Maybe we can get the wiki updated to clarify that and remove the question marks after the Kernel version.

Excellent new product by Hardkernel.
I was about to buy the C4 and a USB3 adapter to SATA but this release is a game changer.

Where is the OLED documentation?
I don't see it in on the wiki or on the img (~/,/etc/init.d/,systemctl --type=service)

The Wiki page will be updated a bit more with a simple method.

I made the repository with simple script to display date/time, OLED can run once you install the package "odroid-homecloud-display" if you are running with Hardkernel's HC4 minimal image or my LinuxFactory repository.

I wonder why RTC is necessary if the device is connected to internet.
It can use NTP and major linux distributions do update there time from time servers.

One use case with RTC is let the device wake up at given time when the device is suspended.

Is there any mechanical support for the drives? I can't quite tell from the photos.

If not, I'm afraid large spinning disks would vibrate quite a bit, and might even find an unlucky resonance frequency depending on disk activity ... that would be bad for the drives, and bad for the board.

Any drive with significant vibration was not balanced properly and should be returned immediately as they will under perform and have a short life. (only ever had to do this once, but it happens)
That said gravity is going to keep them in place. If there was enough vibration force to lift a heavy spinning drive it would lift the whole SBC, or snap the connectors.

    Hi,

    I really can't wait to get this HC4 :)

    Anyone with experience on how long it typically takes the shipment from South Korea to Europe?
    Or if it is easier to wait for the Toaster to be available at distributors in Europe? (based on previous boards launches how many weeks would this take to happen)

    /Daniel

    Shipping takes typically about a week.

    it hasn't yet started selling out and I have already suggestions for next revision :D

    eMMC, 8GB of RAM and 2+ USB ports
    While we are doing the suggestion, why not make one with at least a RAM socket to accept either a 4/8/16 GB DDR4 RAM module (like the ones used on a gaming laptop computer). This way, buyers can just buy the item with 0 RAM and whatever size in a RAM module to use.

    Current AM Logic CPU's line-up have a 4Gb RAM limit. I suggest Odroid-H2+ which can handle up to 32Gb RAM via two(2) SO-DIMM slots

    SATA Interface Performance
    We connected a SATA SSD to the HC4 platform and measured the storage IO throughput. We could observe 390~420MB/s transfer speed which is quite good for many applications.

    Code: Select all

    odroid@hc4:/media/ssd2$ iozone -e -I -a -s 100M -r 4k -r 16384k -i 0 -i 1 -i 2
           Iozone: Performance Test of File I/O
                   Version $Revision: 3.489 $
                   Compiled for 64 bit mode.
                   Build: linux-arm
                                                                 random    random     
                 kB  reclen    write  rewrite    read    reread    read     write     
             102400       4    44097    62373    75362    75511    39859    60806 
             102400   16384   428515   426902   390226   392564   391412   427137 
    A 400+ MBps is definitely a very good performance. Since you did not mention, I presumed the above test result is based on a non-encrypted data stream. If so, the question I have is does the device (oDROID-HC4) come with a hardware encryption chip to encrypt the data stream?

    Yes the C4/HC4 SOC has hardware accelerated encryption @ 570MBps;

    storage IO throughput is conditioned to SSD drive's controller/nand speeds.

    Here's what I noticed so far:

    HC4 w/ Samsung EVO 860 SSD ~ 410 MB/s
    HC4 w/ Samsung Samsung 870 QVO ~ 390 MB/s
    HC4 w/ Crucial MX500 ~ 350 MB/s
    HC4 w/ Kingston A400 256Gb ~ 344 MB/s

    S905X3 CPU was OC'd to 2016 Mhz
    OS tested: Ubuntu-Desktop 20.04 LTS w/ 5.8 kernel

    BTW, HC4 feels snappier and more responsive than C4 (OC'd at 2.1Ghz) while running same OS.

    The HC4 cradle for a 3.5" driver is pretty stable and has virtually no lateral movement. This drive adapter might help address any concern for 2.5" drives.

    @odroid:
    Are you going to make available boards only (without plastic case, etc) ?

    The reason behind it is that I liked the "stackable" form also as I don't plan to run it with hot-swap, I would rather 3D print my case than using HC4 as a "dock" for HDD with them sticking out :) ... also cost savings when buying multiple units as I would have no use for the plastic case (hints at multiple CEPH nodes ;) )
    We have no plan to sell the board separately since there will be little demand.
    If we remove the case shell and the cooling fan, you might save several dollars though.
    Fair enough. Still ~35 per SATA port is acceptable, if you consider that my best alternative is a board with a single lane PCIe to a 4 port SATA controller which leads to similar costs (not sure if I can mention other manufacturer's products here).
    My current project will use 3x H2+ boards hoping that the CPU can run K3S and some lightweight workloads on top of CEPH storage. I'm still considering using HC4's to cheaply extend that CEPH cluster but would 3D print a closed case instead. Still need to finish cooking my yocto recipes before the new hw is available at polin (I live in germany)

    Still .. cannot wait for it :) .. hopefully until then some company will produce something similar to 8 port 2.5/5GbE switch with 2x 10GbE SFP+ cages uplink cheaply ? /dreamon =)

    Sadly the HC4 with OLED are currently sold out. Are we stuck waiting for a long time for the next batch?

    We need 3~4 weeks to make the next batch.

    I feel eMMC option should be added for this SBC, it bring stability to the OS.

    Would it not be better to just put root on sata/ssd?
    (LVM/ZFS/Btrfs could give root redundancy not available on a single eMMC, not to mention all that extra space for snapshots)

    It depend SSD/SATA interface are use with the u-boot as boot-table device.
    Well we need hot plugable SSD/SATA for external data backup, no mater if any filesystem used on the disk.

    I'm with moon.linux on this one. IMHO EMMC should be added if it doesn't increase the cost too much (I'm guessing it would add 3-5$).
    The reason for using it (instead of keeping the OS on the disks) is to allow the disks to spin down when idle (otherwise logs would keep them active).

    If wanting to swap more than one drive or let more than one spinnig drive rest, the sdcard should be OK (the HC2 was stable right?) but maybe the C4 is a better option for conditions where an extra SSD or 6 would help (just have to live with the extra usb wires).

    When building a NAS, I want only data (not OS) on the HDDs. This allows the drives to be moved to an entirely different system/architecture if necessary.

    However, I do not find eMMC to be useful. This is mainly due to size/cost. A 128GB SD card is far cheaper and easier to source than eMMC. This is critical to reestablishing operation after a failure or OS corruption (re-imaging).

    My primary issue is with the "toaster" design. It is not rugged. The exposed drives make them more susceptible to environmental hazards like something bumping into the unit or otherwise causing drive disconnection. I am hoping the community comes up with some 3D printable designs for alternative cases.

    My secondary issue is relevant to all current ODROID products. The power supplies are not power strip "friendly". Inserting the power supply into a power strip will typically block one or more outlets.

    I expect rugged from servers with clips to hold the power cables in but SBCs are trying to be cheap so ruggedness should (where costly) be aftermarket or an accessory.

    A pack of 6-Inch Power Extension Cables are one solution to wall worts but it would be nice if a usbc-sized psu was available.

    Have an upvote. I understand the motivation to use the same power supply like the H2, but the original H2 power supply of rev.A was ok, while the current one is cumbersome. With the H2 one can use alternatively an off the shelf laptop 19V supply due to variable V input, while here getting an alternative 15V power supply is harder.
    But, I have no use for the HC4 anyway - I have no 3.5" disks and upright position is too unstable, sorry. A H2 with SSD for OS and 2x 2.5" for mass storage is now playing NAS for me...

    While other Odroid boards may suite some (including me) better I don't think calling the HC4 physically unstable is fair.
    Giving it some bumps and shakes was the first thing I did and it seemed stable.

    I really like the toaster form. Adding hdd-ssd is very practical and fun.
    It has a better foundation than I thought. For those who worry that I will crash and fall, don't worry, it doesn't have a structure that can easily be knocked over.
    I've tried many drives like ssd -2.5 "-3.5", no flickering.
    Psu cable may be short for some people but that's okay, with a little bit of DIY you can overcome this handicap.

    I mainly use SSD's for NAS storage on HC4, not necessarily in Raid configurations yet.
    I really like the Toaster design and the fact USB3 to SATA has been removed by a more stable PCIe to SATA direct bridge connections. I think some covers like the ones someone post here would make great accessories to secure 2.5" SSD/HDD drives and will be buying them once they become available.

    Once I have Archlinux w/Gnome and Panfrost & 5.8 kernel running on the Toaster from my speedy Samsung Evo 860's, it will be the bomb. Hopefully a Ubuntu 20.10 w/HW acceleration preferable with XFCE(Xubuntu) for HC4 will arrive soon.
    OLED mini screen is great feature to display data from OS.

    I still miss the eMMC slot, but I can live without one.

    My C4 was missing a Petiboot feature without having to sacrifice a uSD to emulate it, and HC4 has it.
    Wasn't easy to find a USB2.0 unpowered Hub these days to use it with HC4(Mandatory Bluetooth & Unifying dongle for me). I managed to buy a few of them just in case.

    So far so good...

    Is it possible to turn off the fan in the HC4 in a simple way?

    I'm looking for a super silent NAS and plan to use 2 SSD without stressing the board too much, so the fan should be just always off.

    The fan will stay off if you don't stress it. On my TODO list is to stress it just so I know what it will sound like.

    Are you saying USB is unstable in some way?
    Sure some quirks may be required to get smart working,
    and the N2 had a driver bug for a week,
    but USB has given me no stability issues over 9 years and many many drives.

    Yes, I've had some serious USB3 stability issues on all my N2 devices since day one when using multiple SSD's/HDD's, and I have two(2) N2's and one(1) N2+ and trust me on this, all three of them had exactly the same issue. I tried also a lot of SSD drives and USB3 to SATA adapters from different chipsets and manufacturers, quirks, etc.
    Never had any of those USB3 issues with my C4.
    HC4 has been rock solid so far working with two(2) Samsung EVO 860 SSD drives.

    Is there any mechanical support for the drives? I can't quite tell from the photos.

    If not, I'm afraid large spinning disks would vibrate quite a bit, and might even find an unlucky resonance frequency depending on disk activity ... that would be bad for the drives, and bad for the board.
    Any drive with significant vibration was not balanced properly and should be returned immediately as they will under perform and have a short life. (only ever had to do this once, but it happens)
    That said gravity is going to keep them in place. If there was enough vibration force to lift a heavy spinning drive it would lift the whole SBC, or snap the connectors.
    I'm not talking about the disk itself being not balanced properly -- I would agree with you on that -- but about the action-reaction from arm movement. While I have no desire to perform the experiment, I would expect that after N moves (we can argue how big N is) the mechanical connection will degrade if not made for that purpose. If I can feel the arm move by putting my fingers on the disk during operation, so can the connector.

    Compare how disks are mounted in high-end cases: screws and rubber as dampers.

    Good thing the sata connector was designed for this purpose and has been used in economy toaster style connections like this for the past 12 years. USB ports on phones fail ridiculously often due to rough use, but I have never heard of a sata port failure.

    My current SATA SSDs are attached to Windows computers and I only tested for file transfer.
    I tested it with my other 2.5 "and 3.5" storage HDDs. again I installed ubuntu-gnonme-wayland on an old 2.5 "HDD" (sataII). The performance was not bad.
    My new cheap SSD arrived yesterday. I installed Ubuntu-Gnome-Wayland.
    In a word, perfect performance, no SBC could compete with this device if it had the horsepower of the N2.

    Off topic:
    I want to say something to @tobeeter, I think you spent all your energy on HC4 for Ubuntu-Gnome-Wayland. N2 is definitely not that stable. I've tried N2 in SDD, tried in uSD, tried in eMMC. It is ok if we can boot up and enter the desktop screen. but has occasional problems getting into the desktop.
    Every boot and desktop attempt with the HC4 is successful. N2, 7 out of 10 attempts are successful. The HC4's desktop login time is faster than N2 +.

    Note:
    I made a video about evolution-calendar-factory. After killing evolution-calendar-factory, the performance increases by 200% :) ok I might be exaggerating but try it, I think maybe I'm not exaggerating.

    The problems with evolution-calendar-factory are the same as for N2, N2 +, C4, HC4. SSD, uSD, eMMC all have the same, similar degree of problems.

    I'd like to absorb a few things about design.

    LEDs are designed on the side. It would have been more informative if he had been lined up behind the oled-clock. especially the sata led is too hidden. I think it was a reverse design to the reason why LEDs are.
