Hello, I have read the documentation and checked a few how-to videos on YT, but I want to be sure I'm not screwing anything up. So, right now I have an array with a single drive parity, all disks are 8TB. I have bought a 16TB new drive to replace the current parity disk - thinking to the future expansions, too. I want to add the actual parity as a disk in the array - so I'll move from 4x8TB (1parity+3disks) to 1x16TB(parity) + 4x8TB (disks). They way I see it should be done is to add the 16TB as a 2nd parity, let it rebuild the array and, when it finishes, remove the 8TB parity and add it as a disk in the array. Is my approach correct and safe? Or should I take something else into consideration? Thanks a lot!

Thanks for the hint, I have changed that setting and the transfer speed it's constantly around 165-170MB/s. Learning something new every day...

Hello, I have built an Unraid server with a Gigabyte Z270M MB, i7 7700K and 16GB RAM. As I had a QNAP NAS before, I have backup my data on various internal HDDs. Now, I have created an internal array with 4 Seagate Ironwolf PRO 8TB HDDs (3+1parity) and a 2TB ADATA Legend 800 NVME as cache. I have connected 2 of my backup drives (Seagate Ironwolf PRO 4TB, NTFS formatted) and mounted them with Unassigned Devices and began transferring the data to the array. My issue is that the transfer rate started at around 150-160MB/s but after a couple of minutes it went down to 75-80MB/s and is capped there. I see that it only writes on the parity and the first disk of the array which I assume is correct (I'm an Uraid noob, so...). I also tried to change the primary storage from Array to Cache, it makes no difference. I was expecting a much higher performance, 150-160MB/s sustained transfer rate should've been OK. I'm attaching a couple of screenshots, maybe it helps.

So, I've (slowly) started to put together my new Unraid server and I'm not sure what the best approach will be. Long story, short... I have the following components: - i7 7700K - GA Z270M D3H (6SATA ports) with 16GB RAM - 2TB Adata Legend 800 NVME (that I plan to use as cache) - (for now) 4 x 8TB Seagate Ironwolf PRO HDDs - I say "for now" as I plan to extend these and get 8 or 10 HDDs in total - case (Node 804) and 600W Seasonic Gold PSU Now, I have also ordered a Dell LSA 9207i controller to be able to extend the 6 SATA ports from the MB. Is that OK to mix the usage of SATA ports from the MB and the LSA controller? I'm asking that because I read various conflicting info - some say it's fine to mix (4 HDDs on MB and 6 HDDs on LSA) while others say that's better to run all disks from similar controllers... the last approach would mean I'd have to buy another LSA controller if I want to have more than 8 HDDs in my array (I only want 1 array with 1 parity disk)! Thanks a lot!

Thanks for the answer. I decided to go a little bit different with the build since I have some other stuff around and will use that (for the moment, at least): - Intel i7-7700K and - Gigabyte GA Z270M-D3H (plus those 16GB DDR4) Both of them are solid performers - better than Biostar in terms of quality or Asrock/Asus N100M in terms of performance (if needed). At the beginning I did not think to use these due to a higher power consumption but I can lower the voltage and play around in the BIOS to reduce the i7 performance/power. Since the GA board only has 6 SATA3 ports, after an extensive search in the forum, I have ordered a LSI 9207-8i and the cables for it so 8+ HDDs won't be an issue. As for the license... I'm coming from QNAP, so I don't have an Unraid license - I need to buy one (Plus). Let's see the Cyber Weekend offers! 😁

Hello, As the title says, I want to upgrade my current setup and after some research I ended up with a couple of options. I'll start with what I have: - QNAP TS-451 (8GB RAM, Celeron J1800) - RAID5 (3+1) made out of 4 Seagate IronWolf Pro 8TGB - so a total of ~24TB available - lots and lots of documentation, personal photos (I'm shooting RAWs and I tend to keep everything), lossless music, and some 4K movies that I stream in my LAN via Plex (for media files, I'm not doing any transcoding or such) As my free space is running low - I still have 3.5TB free but with my photos and music it will be filled completely in the next 6-9 months - I want to move away from QNAP and build a custom NAS with Unraid, a solution that will allow me to add more HDDs in the near future. What I also have lying around is: - Fractal Design Node 804 with plenty of room for at least 8 HDDs - Seasonic 550W silent 80+ Gold power supply - 16GB DDR4 3200MHz RAM Option 1 (~370 EUR - I live in Europe): - Biostar B760MXC PRO 2.0, it has 8 SATA ports, - Intel Core i3-13100T (35W, tray) + cooler Option 2 (~230 EUR) - ASRock N100M with only 2 SATA ports - PCIe SATA X4 Card 6 Port Expansion Card for 6 additional SATA ports - from what I understood Unraid plays nice with the ASM1166 chipset (also, I think there are NVME to SATA adapters, but I could not find any - any suggestions here?) On top of both, I will have to add the ~80 EUR cost of the Unraid license. I'm more inclined towards the first option even if it costs more (the price difference almost covers an 8TB HDD) since I'm not a big fan of adding expansion cards. Also, I'm pretty sure both i3 or N100 will be able to drive my setup with ease since I won't do any CPU-intensive tasks (as I said, my media files are served only locally via the Plex server, without any transcoding). I'm not looking for my solution to be completely silent or to consume as little as possible. I'm mostly want to future-proof this solution storage-wise, by adding more disks, as needed. Any thoughts or suggestions? Should I wait for Intel U300/N300 integrated MBs to show up, would it make sense over the N100? Or, maybe, a 3rd option? Thanks a lot!

Too true, I just noticed... not sure how that got past me as I have studied both cases in detail! I do have a Node 804 that houses my gaming PC - that also needs an upgrade (especially MB and CPU)- so, maybe, I might still buy a 304 and switch some things around... gaming PC in 304 and NAS in 804. Thanks for pointing this out!

OK. So, right now I have a QNAP TS-451 (Celeron) with 8 GB RAM and 4x4TB Seagate NAS HDDs (about 5 years old). My use case is quite simple as I do not need VMs or any complex setup, I only keep my video collection, family photos, loseless music and other personal data and I use Emby (or Plex) to broadcast media to my TVs and mobile devices. I want to build my first Unraid NAS and I was looking at the following parts: Case: Fractal Design Node 304 or Nanoxia Deep Silence 4 (Nanoxia seems to be better suited sound and cooling-wise for 6HDDs, while the Node 304 looks better and fits better in my cabinet... very small price difference but I think I should go with Nanoxia) MB: MSI B460M-A PRO (Socket 1200, 6 SATAs) CPU: Pentium Gold G6405 (2 cores, 4 threads, integrated graphics, nothing to write home about) MEM: Kingston HyperX FURY Black 2x8GB 2666Mhz, CAS 16 HDDs: 6x8TB Seagate Ironwolf PRO (1 or 2 drives parity) Power: Seasonic Core GC, 80+ Gold, 500W First of all, how does it look like? Except the HDDs, Is this OK for my use case? If not, what should I change? Second, as I have only 4x8TB right now, do you see any issues if I want to add 2 more in the array at a later date to expand the capacity? Third and last, is there any reason to add a 256GB SSD (M2) in the configuration, will it bring any performance improvement? From what I read Unraid OS will reside on an external USB, so it does not look like adding an SSD will do any good! Any advice is really appreciated! Thanks a lot!
