May 4, 20188 yr Hi Guys, I'm planing to built my very first unRaid system. But i need some level of speed to my system. After some search and learn i have decided to go the way below. You as experienced user, did you think will work? Network 1x 10Gbe for my main machine work, i will use 10GbE network. 1x 1Gb for hub/switch (until the price of hubs 10GbE goes down) Cache with RAID4 or 5 (plan A) From what i understood, unRaid speed is only from the disk (since it not combine disks), so max speed will be 100Mb +/-. To put speed on the system, it needs cache, but, everything on cache is not protected until be on the disks. So i was thinking in create a RAID4 x4/5 SSD for speed + protect cache from the loss. My plan here is, while the data is on cache, in case of some ssd dies, i can rebuild from RAID4 or 5 and have unRAID cache with data again, is that will work? Cache with 2x nvme (plan B) I saw some system with two caches disks, is that for protection? If so, instead of complicated x4/5 disks to cache raid system. I could go with two nvme drivers for cache. Disks array 2x 8Tb for system security level 4x 6Tb for array Thanks everyone, i'm already looking forward to start build this system:)
May 4, 20188 yr You can do many RAID options with cache, 0/4/5/6, I'm not sure about 10 but I think so. There are some issues with RAID5 in the driver space ATM, so I'd go 0 or 1 for multi disks. I use mine in RAID0 for size boost, but I don't really mind if the cache has a hit every 4-5 years from a disk failure ;).
May 4, 20188 yr Had to dig this up, the best description around for options with Cache pools: https://lime-technology.com/forums/topic/46802-faq-for-unraid-v6/?do=findComment&comment=480421

Super cool I found the the YT video showing about cache and config, where it show raid levels and configs.
