      From what he wrote this is the assumption.

      On the other hand, he also wrote about speed problems. So before you spend your money on anything, think carefully whether it is worth following cheapness. Think carefully about choosing a particular sbc. Because then people cry that they have slow sbc and what to do (raspberry pi).

      then maybe look at Popcorn Hour Transformer

    • Is it?

      If I look at the specs it is a Rockchip RK3328. Rock64. In a case similar to HC1. With HDMI and audio out. eMMC. But "only" 4 cores. And only 5 volt, so that might be a problem. Comes with OMV preinstalled. ;)

      Around double the price of a HC1.

      You are correct. I was remembering wrong. I actually was waiting for a 3.5" popcorn hour.

      Yeah, they killed it by pricing. I proposed the idea right here in this forum to eliminate the USB3 cable/connector hassles by soldering the USB-SATA bridge directly on the board as soon as we realized that RK3328 performance is pretty sufficient for the NAS use case: Building OMV automatically for a bunch of different ARM dev boards

      Unfortunately TL Lim (Cloudmedia and Pine64 founder) made this a Cloudmedia product and not a Pine64 one (that ruined the pricing) and unfortunately the Swiftboard is still not available.

      So unfortunately all we have are HC1 and HC2 right now if it's about an almost trouble free and compact and low energy single disk NAS thingy. I really wonder why no one else picks up the idea and does such a cheap NAS thingie with an RK3328, Allwinner H6 (yeah, software support still sucks) or some other inexpensive ARMv8 SoC.

      well my omv is now raspberry based, so even orange pi zero plus will be a step up for me I guess lol I used raspberry pi and it's pretty sufficient for my need. It used to restart all the time and corrupt the sd image, but when I replaced the power with the official raspberry psu, it works wonder. But yeah, transferring files are s..l..o..w

      Slow but useful when we want to try something like OMV, by using a RPi already bought for another old project.
      Slow but reliable for home users, and some online friends/family.
      Thx to OMV for using this king of hardware.

      But yes, it can be useful to have the good advice from people who knows well those SBC, to find a good ARM product for NAS purpose driven by OMV, if it exists.

      Two mutually exclusive 12V inputs, improved thermal design, 2 more USB2 ports available on headers, fan connector (PWM adjustable) and only one Molex connector any more so I would assume they sell it with one power breakout cable for all 4 SATA disks...

      My only concern is the 88SE9215 that can be seen on one of the wiki pictures (since this chip is connected with just one single PCIe lane -- what we want instead is the 88SE9235 using both PCIe lanes)

      Hmm, I assumed that such a SATA HAT would also be uasbale for the T4. Just checked and the PCIe x2 GPIO is only present on the M4. Bummer :(

      I'll try a combination of either:
      1. M.2 to Msata + Msata to Sata adapters, or;
      2. M.2 to pci-e 4x + PCIe to Sata adapters.
      Or just skip this, buy a 1TB NVME SSD and only use the HDD as nightly backup connected via USB 3.0.

      While this will work, the second ingredient is not an 'Msata to Sata adapter' but simply a PCIe attached SATA controller in mPCIe form factor (no mSATA involved at all).

      Edit: not entirely sure whether it will work. AFAIK data lines are the same with mSATA and mPCIe pinouts but if not then your 'M.2 to Msata' adapter will already be the showstopper.

      I hope you're aware that there exist other RK3399 boards that are equipped with a full PCIe x4 slot (RockPro64 for example). The more adapters you use the less reliable the setup will be.

      mPCIe indeed, not mSATA, mistake from my side.

      And I'm aware such a setup will introduce risk (apart from the risk of using cheap (less reliable?) components).

      Before buying the NanoPC T4 I was also considering the Rockpro64 with the NAS kit. In the end I've chosen the NanoPC because of its form factor and expectancy that the USB3 port would be fast enough. Unfortunately the speeds to the attached 3.5" HDD are slow (10.5 MB/s). Still need to swap the HDD to an SSD to verify if the HDD or the NanoPC is the culprit.

      Edit; just tried the SSD right away, it has a write speed of 216 MB/s. Strange because the HDD had speeds of 180 MB/s in the past.

      1) Around 1W:

      NanoPi NEO2 or Orange Pi Zero Plus: pretty inexpensive, both based on Allwinner H5 SoC, both with 4 real USB2 ports (no internal USB hub used, no bandwidth shared, 2 ports on pin headers), both with Gigabit Ethernet, both able to be combined with useful, inexpensive and performant NAS add-ons (NAS Kit v1.2 for NEO2, NAS Expansion board for Orange Pis). 'NAS performance' 4 times better than Raspberry Pi, when playing USB RAID (never recommended!) it's even 7-8 times better. Since storage here means USB2 the problem is consumption of the used USB-to-SATA bridge (which needs some juice even if the disk behind is sleeping/standby). The trick to get at 1W is to switch Ethernet from GbE to Fast Ethernet (saves ~350mW) and to use the GPIO pins + a MOSFET to also switch off a connected USB-to-SATA bridge if device is not needed.

      Im using the Orange Pi Zero Plus and with your help Ive managed to switch Ethernet from GbE to Fast Ethernet (Thanks).

      Does this only apply if Im using the NAS expansion board?

      Well, if you always want the OPi Zero Plus to operate at 100 MBits/sec then the normal OPi Zero might've been the better choice?

      The nice thing with being able to switch between Fast Ethernet and GbE is that I use this to let my small OMV boxes idle at lowest consumption possible just to switch to Gigabit Ethernet when needed (I use a lot of those boxes as 'backup appliances' for Macs and while the time a backup needs is not important, with large restores and disaster recovery you always want fastest network possible -- so it's nice to switch on demand with ethtool between both modes).

      Wrt overall consumption please keep in mind that saving an additional 0.5W is often not worth the hassles, especially if you compare with what you could save by e.g. 'optimizing' the way you vacuum at home ;)

      Once you manage to let a connected HDD spin down when not active that's already a nice saving. Those GPIO tricks to cut power to external USB disks require some knowledge and if you're not good at this (like me) it always involves the risk of breaking stuff.

      For such low power operation mode where you can easily switch on/off consumers from userspace still the Olimex A20-Lime2 is the device to go. Full UPS mode with an attached battery, no USB-SATA bridge that wastes energy since 'native SATA' port and if you have external consumers (e.g. a connected backup disk) you can easily switch power on/off with sunxi-pio utility. Unfortunately Olimex A20-Lime2 is based on an old and slow dual core SoC.

    • Guys what do you think of this upgrade of the odroid?
      forum.odroid.com/viewtopic.php?t=33781
      Paired with a FANTEC QB-35US3-6G or FANTEC QB-35U31 and a small SSD for SO it seems to be interesting

      It's USB3 storage and everything is behind an internal USB3 hub. Not the best prerequisites for 'reliable NAS operation' IMO but it's currently the fastest affordable SBC at least with multi-threaded loads.

      Once stuff like CPU and IRQ affinity is set I would expect it to be a rather fast NAS (~100MB/s as usual today with fast SBC) but USB storage is... USB storage.

      People not knowing about the importance of used USB-to-SATA bridges in USB3 disk enclosures will run into troubles as always (that's one of the reasons Hardkernel did ODROID HC1 and HC2 and soldered a good such bridge on the PCB)

      What do you expect from those USB3 attached thingies in combination with an SBC?

      • USB3-A receptacle/cable hassles are quite common (way more often issues compared to USB2/Hi-Speed since those additional contacts for the SuperSpeed data lines are laughable tiny and as such you're running really easy into interconnection issues with USB3-A jacks/receptacles)
      • These things usually provide RAID functionality which is an insane idea to run such a huge Single Point of Failure (you need another replacement unit since otherwise your data has gone once the thing dies)
      • What about the consumption of these USB drives boxes?


      If I would want to add up to 4 disks to an SBC I would clearly go the SATA route (taking an old PC enclosure and then implanting a NanoPi M4 with its SATA HAT inside the enclosure and feed the whole setup with an external 12V brick or do something similar with an EspressoBin)
