  1. You can run unbuffered ECC RAM on a Pentium, for instance the G3258 (Haswell), G4400 (Skylake) or G4600 (Kaby Lake). That's more basic NAS territory, a Xeon or Ryzen aren't needed if your your only requirements are a NAS with ECC. You'll need more memory for unRAID 6, btw - I'd go with 4GB as a starting point.
  2. The Xeon E3 is the same class chip as a Core i7 - 4 cores, hyperthreaded (most of them, anyway), etc. While the Xeon E3-128x chips are pretty expensive, the costs of a Xeon E3-127x setup will be more on a par with a Core i7 setup - a few dollars more for the chip, a few dollars more for unbuffered ECC RAM, and a few dollars more for a server class motherboard. But all-in-all, fairly comparable to a Core i7 setup - take a look at the Xeon E3-1275v6. The advantages of an E3 "server class" setup come as much from the motherboard as from the chip - features like dual LAN, IPMI, etc. The Xeon E5 is a full step up. More cores, more PCIe lanes, more memory bandwidth, registered ECC RAM, etc. It will cost a good bit more unless you buy used. The Xeon E5 requires Socket 2011 while the E3 requires Socket 1150/1151 (which is what the Core iX chips use). Socket 2011 chips also use more power than Socket 1150/1151 chips. The Core i7-6850k and similar "extreme edition" chips are also Socket 2011 and can be thought of (over simplification) as consumer level E5's. Based on what you want to do (primarily based on Plex streams), I'd target a minimum of 10,000 Passmarks. A Core i7-7700K would be great for a high end NAS and everything you want to do unless you get serious about VMs - it would have plenty of capacity for unRAID, a bunch of Dockers, and a handful of Plex streams. Dockers are a very lightweight form of virtualization and generally play well together. On the other hand, performance sensitive VMs like to have dedicated cores - and if you start pinning cores, 4 just don't go very far. A 6+ core chip would definitely future proof your purchase - but hardware at that level isn't just a NAS anymore.
  3. My best guess from your Diagnostics is that you don't have User Shares enabled on the Global Share Settings. I'd recommend following the steps above and posting screenshots...
  4. Hello and welcome. You've done a lot of great research, and it sounds like you are close to piecing it altogether. That said, let's focus on the CPU for the moment. Here are several points I noticed: 4-6 transcode streams simultaneously. At roughly 2,000 Passmarks per 1080p stream, you're looking at a pretty good size CPU. Don't forget that unRAID needs some CPU for itself. Up to 4 1080i/4k streams - Do you want to transcode 4k source, or will you just be supplying a 4k stream to a 4k-ready player? If you want to encode/transcode 4k then you will want to look at the latest Kaby Lake processors for their support for HEVC 10 bit video. VMs and Gaming - storing game ROMs and serving them to devices isn't a big deal, but I wasn't sure if you want to actually game in a VM (i.e. IOMMU/VT-d) - if so then you'll need to size appropriately. Which CPU to pick depends on what you're thinking about the questions above. A Kaby Lake i7 or E3 Xeon is probably a great choice unless you want to be serious about VMs and Gaming on your server.
  5. Also, it sounds like you've checked Settings -> Global Share Settings for Enable User Shares, Included Disks and Excluded Disks, but double check the settings there as well...
  6. The SATA controllers you're looking at are generally x8, so the x8 slots of the X9DRL-iF wouldn't be an issue there. If you're planning on using VMs with hardware passthrough, though, you'd typically be using x16 video card(s) which would be a problem.
  7. Ok. Did you play at all with Included or Excluded disks? Shares -> Click on share name "Data", review Share Settings section - probably worth posting a screenshot...
  8. Hi, what share are you trying to copy data to, and are you using user shares, disk shares, or both?
  9. The Dell PERC H310 is widely used in unRAID servers.
  10. My server runs headless, in a closet in the basement and doesn't have externally accessible drive cages. It would be inconvenient to install a drive in there and have it die immediately. My W10 desktop is much more accessible and has internal hot swap bays, so initial testing just works better with Data Lifeguard - and yes, the long test on Data Lifeguard still takes a *long* time. The best approach is probably a few pre-clear passes on a server with external hot swap bays but I'm pretty happy with my workaround approach, it does a good job identifying unhealthy new drives.
  11. WD's Data Lifeguard is a good tool to stress test the drive, as is unRAID Pre-Clear. I tend to use Data Lifeguard as it's more convenient for me to stress test a new drive outside my unRAID box. Then when I add the disk to my server I'll either do a single pre-clear, or let unRAID handle it as it adds it to the array.
  12. Ideally you want something with an LSI chipset. Unfortunately availability is a local thing and I can't speak for the UK. We have a number of UK forum members, though, who could help. Perhaps @HellDiverUK can recommend a good approach for SATA controllers in the UK...
  13. Just do a quick search here on the forums on "Marvell", which is the chipset on the Supermicro cards. You won't like the results. That said, the SASLP and SAS2LP were the preferred controllers for a long time and a lot of people are still using them successfully - but as you can see from the search results, there are good reasons not to use them in a new build if you have a better alternative.
  14. Hi - Since you are putting in a couple of monster CPUs, I assume you are either planning to do lots of Plex transcoding or do some serious VMing. In either case, especially with VMs, the SAS2LP is no longer the preferred SATA controller. Get something LSI based like an IBM M1015, Dell PERC H310, or LSI SAS9201-8i HBA (all on eBay, and the first two would need to be flashed). Curiously, that motherboard doesn't have any x16 slots - were you planning any high end video cards?
  15. A Pentium G3258 is an inexpensive 1150 chip that would be fine for a basic NAS, but IMO as soon as you said VT-d and passthrough you're not talking about basic NAS anymore (and the G3258 doesn't support VT-d). On Haswell I think you'd need to go up to a Core i5 to get VT-d.
