RAID recommendations

Hello rvkanten,

for setting up a disk system, here are my recommendations, based on the information you gave:

- No special read/write policy - or is there something in the options which makes you doubt?

- No write caching until you have a battery powered cache!

- 1 hot spare disk or 2

- stripe size can be something between 32 and 256 kB. Choose the biggest in this range, what your controller can support

- Write scales with every 2 disks, so 10 disks have 5 write channels parallel

- Read scales linear

- Read and write can be done in parallel, but as should be clear, not in every channel at the same time - physics will win :)

- When you have SSDs, they are 5-10 times faster than normals disks :)

And this may helpful, if you look for the last percentage of performance, or use 4 K disks or SSD.

I checked on my computer and Windows did it well, but better proove :)
