  • Both WD Blues and Seagate Barracudas are (often) CMR.

    I don’t know about WD Blue but modern Barracudas (not Pro!) use SMR.

    But anyway, I wanted to add a thought regarding SMR vs. CMR: It’s true that SMR has inferior write speed compared to CMR and that you can experience the effect even after writing a few gigabytes. I don’t know if I would call it unbelievably slow though: When writing to SMR drives, I experienced write speeds around 30 MiB/sec which is slow but considering you may be writing to a NAS that is only connected to a 1 Gbps network it is only around 30 % of the write speed you may reach with proper drives. It’s slow but it gets the job done when you’re not in a hurry and have a tight budget.

    Also there are other possible bottlenecks you may encounter: I for example built my homeserver with used enterprise drives in mind and therefore opted for software RAID 6 for double the fail-safety. Turns out that writing to that array is so heavy on my servers CPU that it throttles writing to almost the same point as SMR drives which defeats the whole point of using enterprise drives. 🤣 This may not be a problem for OP because they wrote about buying 2 or 3 drives but everyone should always consider the whole system and not single components.



  • I am using DuckDNS and it’s working perfectly for me. I use the DynDNS feature of my Fritz!Box to update my DuckDNS-IP. The documentation on their website is spot-on for me, even for my IPv6 and I never had any issues with DuckDNS.

    What I like most about the service is the possibility to use subdomains like my-service.my-username.duckdns.org. I don’t know whether this is a commong feature or not.

    When you had problems updating your IP Adresse did you consider that DNS information takes some time to propagate through the internet? I think it is not guaranteed that you can access a recently changed domain.

    How did you test your DuckDNS entries?


  • Earlier this year I built something similar, although with more space for hard drives:

    I used the following components:

    Mainboard Topton N100 (AliExpress) This is actually a BKHD 1264 NAS 136,69 €
    RAM 16 GB Crucial DDR5-4800 (Mindfactory) 40,78 €
    Case Jonsbo N2 (???) 138,83 €
    PSU 300 W bequiet SFX Power 3 (Mindfactory) 50,39 €
    M.2 system drives 2 X 128 GB Patriot P.300 (Mindfactory) 25,78 €
    392,47 €

    For storage I bought used 4 TB drives from ebay for around 40 € each.

    Now the system is running 5 x 4 TB in RAID 6 as well as a 256 SATA SSD I had laying around as cache.

    The system is using 25 Watts in idle with those 5 HDDs, 1 SATA SSD and 2 M.2 SSDs.

    It’s a bit more you’ve been asking for but this option would offer you more expandability down there road.
