Most motherboards nowadays support mirroring. All the dell laptops I've
bought in the last 2 years support raid mirroring, and half of them
don't
even have two hard drive bays.
Yeah; but the BIOS raid is almost always really just software raid; and
on linux the built-in software raid is generally considered better
than the software raid plus keeping the configuration in the BIOS.
Is this different in windows? Is the bios raid considered better
than software raid alone? (or maybe the software raid is only available
on the $900 windows server version, and BIOS raid is considerably
cheaper if you are building a desktop system?)
What do you mean?
If it's in BIOS, then it's hardware. Below the OS, regardless of what OS
you're talking about. Right? Or is there some new BIOS-vs-software
standard I'm not aware of?
At that level it's useful to differentiate between the chip and the
microcode (firmware). The BIOS itself is actually software, which is why
you can update it (e.g. AmiBIOS, Phoenix BIOS, etc.). RAID in hardware
generally means parity (XOR, DP, etc.) calculations being supported by
special circuitry. That isn't the case for the BIOS chipset, thus it is
software RAID.
