July 28, 20232 yr Hello to all, I finished my new NAS and I convinced to install as OS unraid! Here below my hardware in detail: - mainboard AsRock J4125B - 8Gbyte of DDR4 - sas/sata controller LSI SAS 9207-8i - storage devices n° 6 Samsung Evo 870 (4Tbyte each) + 1 Samsung Evo 870 (256Gbyte spare) - UPS Eaton Ellipse Eco 650 USB Din What I think to do is to use 1 Parity disk and 5 as storage disk (all 4Tbyte each). First of all, I have two doubt about the configuration: 1) I understood that cache disk is normally used to increase reading velocity when you use mechanical hard drives, but I'm thinking to avoid it because all my storage disks are SSD. So, can I create my NAS without any cache disk? 2) Where the Unraid OS will be installed finically? Can I use my last SSD (Samsung EVO 870 256Gbyte) for the OS? I would like to avoid to use USB pendrive for OS.... Many thanks in advance for any reply! Jacobbe73
July 28, 20232 yr 1). Using a dtive for cache is about improving writing (not reading) speed but is completely optional. 2). The OS is not ‘installed’ in the traditional sense. It is always loaded off the flash drive at boot time to run from RAM.
