    1. Uninterruptible Power Supply (UPS) recommendations and advice

      Hello everyone,

      I usually do my own research, and then I try to find multiple matching results and afterwards, read specifically in detail about each recommendation, but, I have to be honest that for UPS recommendations that I’ve seen, it seems to be a very personal recommendation depending on the wattage and connected devices.

      First of all, most people recommend CyberPower or APC, but I’ve also seen some recommendations for Eaton. Is there any other brand that I should be looking into?

      The devices I would like to connect to a UPS would be: desktop, TV, Apple TV, NAS, router and probably my Nintendo Switch.

      There are some general things I've found out while searching that I think I would like some confirmation:

      • I actually think I should buy two UPS's, or? I think just one for the desktop and another one just for the remaining devices, since the desktop uses a lot more wattage.
      • Pure Sine Wave: It does not matter for smaller stuff (routers, etc) but it seems that anything above 70 W, it should use a UPS with this. So, that would mean I need pure sine wave, since my desktop and TV definitely use more than 70 W of power.
      • Some people said to search for a UPS with line conditioning so that you always get a perfect sine wave. Would you agree?
      • USB connection (not a faux USB!) so that the NAS detects the power failure and shuts down gracefully.
      • It is important that the UPS has removable battery for better longevity.

      How would I choose a UPS? Do I need to see the total wattage of all my devices and then pick the UPS accordingly? Anything I'm missing?

      My budget would be up to €100 or €150 in case it is really worth it.

      Thank you in advance for all replies.

    2. Synology NAS Recommendations & Questions

      Hey everyone! Sorry if this is a long post, but I've done my research and I would like to make a few questions. I've decided that I would like to buy a NAS mainly to storage all of my documents,...

      Hey everyone!

      Sorry if this is a long post, but I've done my research and I would like to make a few questions.

      I've decided that I would like to buy a NAS mainly to storage all of my documents, photos and videos, so that, I can access them from multiple devices and also use it to upload important documents to Backblaze B2. Then, I've actually discovered that I can install a few Docker containers and I could use it as a media server (Jellyfin) and serve the content to my Apple TV (neat!).

      I considered a QNAP (better hardware for the price) but everyone recommends Synology instead (because of the stronger security and better overall software), but to be honest, I'm not sure what should I get.

      My budget would be to buy a NAS (without counting the disks) below €1000. Ideally, €500-600 but I don't mind stretching to the €700 mark, if it is really worth it.

      Spoiler alert: I think, it should be the DS920+ (4-bay) or the DS1520+ (5-bay). I think a NAS above 4-bay is better for future-proofing.

      Looking here in Germany at price comparators, I could buy the DS920+ for €663 and the DS1520+ for €750. But these prices seem to be at an all-time high :(


      Questions & Assumptions:

      0. I'm not sure if the price difference of about €100 is worth the premium to get the 5-bay model. There are only two differences between these two models: The 5-bay has one extra slot, and it has 4x 1 Gbe LAN ports instead of 2x 1 Gbe. All the rest is the same. What is your opinion?

      1. I've read that if you run a few containers (~10) it consumes quite a bit of RAM (~3 Gb), so it should be ideal to have at least 8 Gb. This is the reason I've said that I think I can only choose the DS920+ or DS1520+. Looking at official Synology resellers, these models, seem to come already with 8 Gb, and they are within my budget. Is my research wrong?

      2. These two models, have an encryption engine. I think this is necessary to encrypt my files before sending them to Backblaze, or?

      3. A lot of people seem to say to simply pick Synology's hybrid RAID setup called SHR-1 or SHR-2. I would go the easy way here and pick one of those two. Would you think that is a bad idea, and it is better to pick a specific (standard) RAID? I've read about the long long long RAID rebuild that could happen in some situations, and picking the "right" RAID could decrease the rebuild in days (or weeks!!!!).

      4. In case, I choose a NAS model with Nvme cache slots, most people say it is not worth it to use if you are not running Virtual Machines and the SSD’s "burn" really fast. I have no interest on VMs.

      5. Most people say to pick an Enterprise (Server) HDD instead of a NAS HDD mainly because price is similar in some cases and Enterprise has longer life and warranty. I should also pick a CMR HDD which is helium filled. 5400 rpm would be preferable to 7200 rpm because of the noise. Sadly, all Enterprise HDD's and most of NAS HDD's are 7200 rpm. Is the noise difference that big? The NAS will be in our living room.

      6. Is 8 TB still the best cost per Terabyte?

      7. I was extremely sad to hear that the Hitachi hard drive division was bought by WD. I've had lots of misfortune with WD drives (and let's not forget the debacle with the SMR and CMR drives) and I would prefer not to give money to them, but, nevertheless, I'm still tempted to buy the Ultrastar drives that belonged to Hitachi. Does anyone know if WD kept the components, manufacturing processes, staff, etc., that made these brilliant disks?

      8. Following the HDD topic, what is your experience with Seagate or Toshiba drives?

      9. These two NAS models have the same Intel Celeron CPU, which supports hardware transcoding. To be honest, I don't know in which cases would that happen. It seems if I use Infuse on the Apple TV it would never transcode (and instead direct play) because Infuse would do the transcoding in software. Should I take in account that hardware transcoding is a must-have or a nice-to-have?

      10. Would you recommend having a CCTV system connected to the NAS? Should I dedicate one entire HDD just for the NVR system? Would a standalone NVR device be better?

      11. My last question is: Should I just wait for the new model of the DS920+ or DS1520+? The 20 means it was launched in 2020 (in Summer specifically) and it seems Synology refreshes the model every two years., that means, a new model would be available in Summer this year. Most people say it is not worth the wait because Synology is very conservative in its model updates/refreshes. People are saying that a better CPU will be of course available (do I even need that for my use cases?) and probably upgrade the 1 Gbe LAN ports to 2.5 Gbe or 10 Gbe (10 Gbe I really doubt it). I've read that a 4K stream does not fill a 1 Gbe bandwidth, and you could theoretically have three 4K streams in a single 1 Gbe connection. If all else fails, I could just do a link aggregation of the two ports to be 2 Gbe, or?

      12. Anything I'm forgetting? Should I be careful with something in particular?


      I know I should buy a UPS too, but I think I'll create a separate post regarding this topic because I would also want a recommendation regarding a UPS for my other devices.

      I know that I could actually build my own NAS and use Unraid for the OS. Furthermore, I'm just at a time in my life with too much on my plate (baby and small child) and having something that just works is preferable. When they are older and more independent, I'll have more time to investigate this option :)

      Again, sorry for the long post. Thank you everyone!

    3. Has anyone with a WD NAS formatted drives for another system?

      This is a total longshot. I moved away from a WD My Cloud EX4100 w/ 3x WD Reds to a new box. I bought two more drives for the new one to make the move easier. After the move I took the drives out...

      This is a total longshot. I moved away from a WD My Cloud EX4100 w/ 3x WD Reds to a new box. I bought two more drives for the new one to make the move easier.

      After the move I took the drives out to format them only to find that each 4TB drive shows a partition of 1.8TB on any other system (diskpart with W10 LTSC, Disk Utility MacOS, and GParted with Ubuntu.) Inside the EX4100 the drives show their full capacity.. and I just don't get it.

      I reached out to their support, but I don't expect much of a response.

      Anybody have any idea why the heck this could be happening? This seems crazy. I don't mind buying more drives, but it seems like a waste when I've got 12TB just sitting there.

    4. Would this be alright for a NAS?

      Right now I've got a shitty WD EX4100 and everything was sort of running along nicely with docker and all, but today it rebooted and decided that it didn't want to do anything with docker anymore....

      Right now I've got a shitty WD EX4100 and everything was sort of running along nicely with docker and all, but today it rebooted and decided that it didn't want to do anything with docker anymore. I got the thing before I got into Linux and its time to move on.

      Someone locally is selling the following for $250CAD

      • Quad core Celeron @ 2Ghz
      • 8GB RAM
      • Fractal Node 304 case
      • 2x WD 2TB Red 3.5" hard drives
      • 120GB Kingston SSD
      • 700 watt semi-modular power supply

      All I run are the following:

      • nzbget
      • sonarr
      • qbittorrent (but I'll switch to a better one)
      • serve up content to my HTPC (running Kodi, so no transcoding or anything)

      I don't need the drives that come with it. I'll be putting in 4x 4TB WD Reds. Right now the box is running Open Media Vault 6, so I'll give that a swing, otherwise it'll just be Ubuntu server.

      How does this sound? I'm not opposed to spending some money on a new NAS, I just want something simple that I don't have to fuck around with too much.


      I ended up going with the HP Proliant

      OS: Ubuntu 20.04.3 LTS x86_64
      Host: ProLiant ML310e Gen8
      Kernel: 5.11.0-43-generic
      CPU: Intel Xeon E3-1230 V2 (8) @ 3.700GHz
      GPU: 01:00.1 Matrox Electronics Systems Ltd. MGA G200EH
      Memory: 32GB
      

      It's pretty good so far. Thanks everybody!

    5. Does reformatting an ext4 partition fix bad sectors, and what are they anyway?

      My Linux desktop is having a bit of difficulty with bad sectors. Lately I've had to boot into recovery and run an fsck a few times to try to fix a problem where the OS drops into read-only mode at the drop of a hat. Today I tried copying some files from one directory to another and got the following error message:
      cp: error reading "foo/bar": Input/output error

      I've just booted into a live USB and run fsck /dev/sda1 -c and it fixed a load of bad sectors, but the above error message is still happening.

      A bit of googling tells me that this is down to bad sectors on the SSD, and I'm not really sure what that means. Is anybody able to enlighten me? And as a follow-up question, would reformatting the hard drive resolve the problem, or are there any other things I can try to fix it?

    6. Choosing a new printer

      I'm thinking about getting a new printer. My needs are basically to print out textual documents 2-3 times per month from macOS. I don't need to print photos. I will not buy an inkjet because of the outrageous price of the ink. I would like to have fax support (my spouse sees a lot of doctors and they still use fax machines a lot, and we're not comfortable sending personal medical info via a fax service on the web), and it would be nice if we could also scan documents. So I'm thinking a multi-function device.

      We currently have a Brother 7840W MFC with print, fax, copy, and scan. It's over 10 years old (maybe 15?) and I dislike it. It's been slowly losing functionality over the past 5+ years. The WiFi went out, but I was able to connect it via wired ethernet to a computer and share it from there. The drivers insist that there's a paper jam, but there isn't and it prints just fine (but sounds like some of the internal mechanical components are going to die any day now.) The UI of the printer is awful. I recall having to use the phone pad to enter my WiFi password, and it was like texting on a Motorola StarTAC. (Like if you want the letter "C" press the number "2" three times, etc.) The drivers and related software don't work like normal macOS software. (Disclosure: I also once wrote a scanner driver for Brother and it was horrible, but they shipped it, so I'm not real comfortable putting their software on my computer. But that was 25 years ago, so maybe they're better now?)

      I've heard horrible things about the drivers and software of most other major printer makers - HP, Epson, Lexmark, etc. I'm guessing what I'm looking for doesn't exist, but I just want a multi-function device in as small a package as is reasonable, and with a UI on the device and software that doesn't suck and that won't die on me in < 5 years. Does such a thing exist?

    7. Would it be bad to mount a macbook pro upside down on a VESA tray?

      I've got a smaller desk with two monitor arms -- one with a monitor (left side, different system) and one with a VESA mounted tray for my macbook pro (late 2013 15".)

      I'm going to be adding a 1440p monitor from the macbook pro, but I'm short on desk space. Instead of having the laptop on the tray normally, if I lay it lid down with the laptop portion up, the laptop base could sit behind the new monitor with the screen coming out the bottom -- perfect for static applications like VSCode, iTerm2, etc.

      Here's a mock up. The thicker outline represents the macbook pro screen.

      Can anybody foresee any issues with this configuration?
