Internal RAID

I have no idea what Internal RAID is... I was configuring a laptop and it had the option if I wanted Internal RAID or not...

I don't even know what RAID is... just the hard drive? I think it has something to do with the hard drive but I'm not so sure.

In the Apple it is an external hard drive.

Does your laptop have more than one internal hard drive, Bogey?

If I remember/have this correctly, RAID is a scheme for treating multiple hard drives as if they were as single unit, to increase storage and performance.

There's a few different ways to set it up - called Levels - that adjust how it works. For example, in RAID 0 nothing is duplicated between drives, so it's like having one huge drive (this has quite some potential to fail and crash everything, esp. if you're running a ton of drives), while in RAID 6 (the highest level), a large amount of data is made redundant across drives, so you still get SOME extra space, but your rate of failure/crashing is much lower (I think in raid 6 two drives can crash completely and your system can still run - depending on the number of drives in it).

I don't remember exactly what makes RAID work better than simply having multiple separate drives, but as I understand it it's mostly a performance thing (RAID should have better performance).

Oh ok... that makes sense...

That makes me feel scared of RAID (except for RAID 6)...
