Aye - I won't be using 3ware again. I thought about doing RAID-10 on the controller I have at home (very reliable, touch wood), but decided against. Like I said, it's a bad vibe gained from two catastrophic failures in a short space of time. RAID-10 wouldn't exist if it wasn't reliable.

Heh, tell that to RAID-3 & 4 & 6
If it's good enough for banks and large enterprises, then it's good enough for me It helps to understand these things, but when it comes down to it, you rely on what's tried and tested.

Just been reading up on raid 10 and it does look like a good solution. However I gather that when a read instruction is sent through, it will be covered by the raid 0 array? So in my example above, two drives will be used.

Depends on the controller dude. That's how it should be handled though yes, no reason to go into the mirror pair for reading.

Got it. I may need to increase the capacity of my drives if doing raid 10 then. Seeing as I will end up with one array of 160gb?
2*raid 1 mirror then the raid 0 over the top is 160? |

Nay, 320. Stripe 2x160's = 320, then mirror that pair.

Nay, 320Gb. You stripe together 2 discs and then mirror the stripe set.
