If you're using Live (Linux), then you'd probably find that NFS is a good way to go for accessing your FreeNAS box. Tweak-SSD is an application which can apparently help you improve the speed of your hard drive by implementing things like Superfetch which is able to keep frequently used files in cache. If the Emby cache could use RAM, instead of SSD or HDD, that would really speed things up I think. 5" bays not m. I hope this post helps you in some ways. FreeNAS uses ZFS to store all your data. 5" rackmount chassis in today's marketplace and simplify upgrade and maintenance procedures. If you are installing FreeNAS™ on a headless system, disable the shared memory settings for the video card in the BIOS. And any write applications only happen at 5400 or 7200RPM HDD speed. This provides SSD-like write characteristics, and SSD-like read characteristics for frequently or recently read data. The best way to compare is to look at real-world tests we have carried out at SimplyNAS, as we simply go through 1000's of drives per month and have rich and. The SLC SSD drives used for ZIL drives dramatically improve the performance of write actions. Reading up on some FreeNAS threads and their own Hardware Recommendation page I think that I don't actually need a ZIL drive since sharing will be using SMB (Windows enviroment) and a ZIL drive is recommended for NFS or if you have lots of I/O. And it really depends on what SSD you are using. In this mode, Qtier constantly monitors I/O activity and keeps active data that requires minor mostly random read/write operations in SSD read-only or read-write cache, and other data in the tiered storage, while automatically moving data between tiers. 2 NVME SSD for boot drive - FreeNAS no longer boots and loads into RAM like previous versions so flash drives are no longer recommended.
