00:00:00.160 --> 00:00:06.560
Welcome to TechQuy. Today we're going to tell you all you need to know about RAID

00:00:03.679 --> 00:00:10.240
zero, RAID one, and RAID 10 as fast as possible. You've probably seen reference

00:00:08.320 --> 00:00:14.880
to RAID somewhere, but what does it mean? It stands for redundant array of

00:00:12.719 --> 00:00:20.400
inexpensive discs, and it basically means using multiple drives or discs to

00:00:17.760 --> 00:00:24.720
achieve better performance andor better reliability. RAID zero is all about

00:00:22.800 --> 00:00:28.800
speed. It contributes nothing to reliability except to actually make it

00:00:26.800 --> 00:00:33.360
worse. So it involves taking two drives or more and actually striping the data

00:00:31.039 --> 00:00:38.559
across all of the drives. This means you get to keep all of your capacity and you

00:00:36.000 --> 00:00:42.160
get to have in theory with two drives double the read and write performance

00:00:40.320 --> 00:00:46.800
but in the event that one of the drives underos a hardware failure you will lose

00:00:44.480 --> 00:00:50.559
all of the data that was stored on both of the drives. This configuration is

00:00:48.879 --> 00:00:55.120
only ideal if you're going to be doing very frequent backups or if you are

00:00:53.199 --> 00:01:00.079
going for the most extreme performance possible, such as running multiple SSDs.

00:00:57.680 --> 00:01:04.720
RAID one is all about reliability. You get the capacity of one of your drives.

00:01:02.399 --> 00:01:09.200
You get the performance of one of your drives, but you get the redundancy of

00:01:07.360 --> 00:01:13.280
two drives. That means if one of these two drives I have here fails outright,

00:01:11.600 --> 00:01:16.479
all of the data will still be there. There's no performance overhead for

00:01:15.040 --> 00:01:21.280
running RAID one. You're still going to get the full performance of the drives,

00:01:18.479 --> 00:01:24.479
but the more drives you add to a RAID one, you're always only going to get

00:01:22.799 --> 00:01:28.000
half the capacity that you would otherwise have. The advantage of RAID 1

00:01:26.479 --> 00:01:32.640
is it's extremely safe. So, I would trust most important documents to a RAID

00:01:30.320 --> 00:01:36.720
one array. RAID 10 combines what's good about RAID zero and what's good about

00:01:34.479 --> 00:01:40.240
RAID one into the same thing. So, you're taking four drives, you're striping

00:01:38.320 --> 00:01:45.040
these two and striping these two, then you're mirroring these two against these

00:01:42.880 --> 00:01:49.040
two. So what that means is you get about double the performance of an individual

00:01:46.880 --> 00:01:54.159
drive. You get double the capacity of an individual drive, but you could lose up

00:01:51.200 --> 00:01:59.520
to two drives in a RAID 10 array without losing any data. This is great where

00:01:56.560 --> 00:02:04.479
performance is needed, space is needed, but you don't necessarily want to invest

00:02:01.759 --> 00:02:08.879
in an expensive RAID card solution like this one. There

00:02:07.439 --> 00:02:13.360
are types of RAID that we haven't covered in this episode, but we will make another one. So there will be an

00:02:11.760 --> 00:02:18.640
annotation once that's done. You can go ahead and click on that to learn about them, but those are generally reserved

00:02:16.400 --> 00:02:21.599
for more professional applications. If you are deploying some kind of a RAID

00:02:20.319 --> 00:02:25.760
configuration, I would definitely recommend posting in the linesttips.com

00:02:24.080 --> 00:02:30.239
forum and asking for some help because RAID can be a little bit tricky to set

00:02:27.520 --> 00:02:34.640
up. Last but not least, RAID is not a substitution for backing up. Redundancy

00:02:32.720 --> 00:02:38.560
is not the same thing as a backup. Even if you're running a RAID, you are still

00:02:36.319 --> 00:02:41.920
susceptible to things like viruses or accidental deletion or other human

00:02:40.400 --> 00:02:45.840
error. So, make sure that you're doing regular backups.

00:02:44.160 --> 00:02:49.200
