Hi all, My desktop computer hard drive is now full. I have offloaded a couple of hundred Gb to an external expansion drive to give me breathing space. So I am looking at keeping sda and if possible adding sdb and sdc as a RAID arrangement, from my reading I am leaning toward a software RAID 1 (mirrored drive) using SATA drives. I am progressing further along my intended path of returning to professional photography so data security is now imperative. Can I keep sda as my boot disk and just run sdb and sdc for data storage? sda is 1Tb and sdb and sdc are identical Seagate SATA drives of 2Tb each. I run OpenSuse Tumbleweed. I was intending to get an SSD of 500Gb for my post production work with output being stored only on RAID. Am I on the right track here or do I have incorrect expectations? Many thanks Andrew Greig
