How big is a RAID 10 comprising 4 x 120Gb disks?
Seems like a daft question but I'm a little confused.
Poweredge 1600SC CERC ATA100 with 4 120Gb drives. 2 arrays each with 2 x 120Gb in Raid 1 striped. By my reckoning it should leave me with a usable volume of 120Gb. Disk Manager reports 223.49Gb!
Can someone lift the veil of ignorance on why this is so?
Many thanks

I hope this helps, and I did not just say what you already know. :)

Thanks, of course, and I knew there was something stupid in my question. The arithmetic got 'mirrored' (as a Hall of Mirrors) before installing the new OS.
