And I was wondering why you would need more than 2 hard disks for mirroring. It can be either : - n-way mirroring : you want to have n identical drives, thus you can live with up to (n-1) failed drives. - some kind of RAID "10", as Russel pointed out, where you would do in fact RAID 1 over multiple RAID 0 arrays. > I have always two disks parallel (one original and one mirror) > OK, it's clearer now. > Had problems with Software RAID, because the mirror is not > bootable and after a shutdown thy Server was not starting. > > I think, I can use only Hardware RAID. > Obvisously better. > >3ware.

You can get 256 Mb or more for about 100 Euros. Once you get a cheap CF-to-IDE adapter (something like 20 Euros), you plug them as IDE drives. Very reliable (almost no need for mirroring), almost zero power consumption, no noise, no heat. We use them in several "appliance like" servers at our customers. The only drawbacks are : - capacity (but as you said, for lots of tasks, that's not a problem) - PIO only. Thus quite slow, about 1 MByte/sec.

lol, all over the place does not incl NZ.

Hardware IDE RAID-1 controller recommandation
Hello, curently I am installing some new Servers and I need Hardware RAID-1 Controllers for two, four and eight Harddisks. Can anyone recomand some ? Ic possibel with HOTSWAP. Please note, that I have only acces to german distributors. Is there a RAID-1 Controller which support PIO Mode 4 Drives ?
