Write speed is somewhat slower due to parity updates. Any drive not being currently used can be spun down.īecause of this, read speed from the parity array is at the speed of the single disk being read. Each file is completely contained on a single data disk. Each data disk is an independent filesystem which can be read all by itself on any Linux. Thanks for reading, hope you can help me out here. What's the real purpose of the cache drive? Can I use it to quickly write to the NAS and it then distributes the files to the hard drives? Should I curb my expectations regarding speed improvements? Is Unraid more suited for backup rather than fast network accessed files? Is Unraid suited for my use cases? Are there apps that I can use to enable functionality similar to my Synology? Regarding hard drives, since I had a great experience with my WD Reds, I would want to stick with the brand but increase overall capacity to 6x 4TB with two drives as parity drives. but then I read that that's not really the purpose of the cache drive, it's more for VMs and stuff like that? Can anyone here clarify please? I was also thinking about using an SSD as a cache drive so at least writing to the NAS would be quicker. The question is, is Unraid even suited for fast access to network files? I have read conflicting things about this with some people claiming their read speeds dropped when switching to Unraid with the same hardware. My home is 10Gbit ready, so there shouldn't be an issue there with the right NIC in my planned build. What I want to achieve is not only larger capacity but also quicker access to my files over the network. Remote access via web interface and Android apps (DS file, DS get) to retrieve / store files, add torrents to queue / check on queue Work with media files directly from the NAS for video projects Overall, these files already make up more than 4 TB on my current NASįamily media server (we use a Raspberry Pi4 running Kodi on our living room screen to show our pics/vids) mp4 screengrabs but also 4K files directly from my drone or DSLR), photo (jpeg and Nikon NEF format). I never used Unraid, so I have a few questions about that, but first, here are my use cases for a NAS:īackup for media files: video (mostly. I want to upgrade to something a bit more modern and am currently looking at a DIY option with Unraid as its OS. I currently own an aging Synology DS413 with 4x 3TB WD Red disks.
