Hardware vs Software Raid

Hmm.. Which is better?

I would say software raid is better*, my reasons:

  1. Software raid follows the OS around, upgrade all your hardware, your raid array will still work (In Theory)
  2. Software is easy to update, Firmware is not
  3. If your on a budget, do you really want to trust a cheap raid controller?

[*] Under most conditions, ie. without big budgets, mission critical servers etc…
