Welcome to TechQuy. Today we're going to tell you all you need to know about RAID
zero, RAID one, and RAID 10 as fast as possible. You've probably seen reference
to RAID somewhere, but what does it mean? It stands for redundant array of
inexpensive discs, and it basically means using multiple drives or discs to
achieve better performance andor better reliability. RAID zero is all about
speed. It contributes nothing to reliability except to actually make it
worse. So it involves taking two drives or more and actually striping the data
across all of the drives. This means you get to keep all of your capacity and you
get to have in theory with two drives double the read and write performance
but in the event that one of the drives underos a hardware failure you will lose
all of the data that was stored on both of the drives. This configuration is
only ideal if you're going to be doing very frequent backups or if you are
going for the most extreme performance possible, such as running multiple SSDs.
RAID one is all about reliability. You get the capacity of one of your drives.
You get the performance of one of your drives, but you get the redundancy of
two drives. That means if one of these two drives I have here fails outright,
all of the data will still be there. There's no performance overhead for
running RAID one. You're still going to get the full performance of the drives,
but the more drives you add to a RAID one, you're always only going to get
half the capacity that you would otherwise have. The advantage of RAID 1
is it's extremely safe. So, I would trust most important documents to a RAID
one array. RAID 10 combines what's good about RAID zero and what's good about
RAID one into the same thing. So, you're taking four drives, you're striping
these two and striping these two, then you're mirroring these two against these
two. So what that means is you get about double the performance of an individual
drive. You get double the capacity of an individual drive, but you could lose up
to two drives in a RAID 10 array without losing any data. This is great where
performance is needed, space is needed, but you don't necessarily want to invest
in an expensive RAID card solution like this one. There
are types of RAID that we haven't covered in this episode, but we will make another one. So there will be an
annotation once that's done. You can go ahead and click on that to learn about them, but those are generally reserved
for more professional applications. If you are deploying some kind of a RAID
configuration, I would definitely recommend posting in the linesttips.com
forum and asking for some help because RAID can be a little bit tricky to set
up. Last but not least, RAID is not a substitution for backing up. Redundancy
is not the same thing as a backup. Even if you're running a RAID, you are still
susceptible to things like viruses or accidental deletion or other human
error. So, make sure that you're doing regular backups.
