1 00:00:00,869 --> 00:00:02,110 In this demonstration, 2 00:00:02,110 --> 00:00:04,140 you're going to learn how to create a software RAID 3 00:00:04,140 --> 00:00:05,730 on a Windows machine. 4 00:00:05,730 --> 00:00:07,610 My machine has a few hard drives, 5 00:00:07,610 --> 00:00:08,880 and we're going to go ahead and use 6 00:00:08,880 --> 00:00:10,089 the Windows disk management tool 7 00:00:10,089 --> 00:00:12,340 to setup two different RAID systems on it. 8 00:00:12,340 --> 00:00:14,380 Now, one is going to be a RAID 0, 9 00:00:14,380 --> 00:00:16,990 which is going to provide us with more speed and performance 10 00:00:16,990 --> 00:00:18,960 by splitting the data being read and write, 11 00:00:18,960 --> 00:00:21,800 into to two separate drives on two different disks. 12 00:00:21,800 --> 00:00:24,100 Now, each disk is going to get half of the data. 13 00:00:24,100 --> 00:00:25,760 This means, if I lose one of the drives, 14 00:00:25,760 --> 00:00:27,569 I'm going to lose all of the data. 15 00:00:27,569 --> 00:00:30,853 Now, on the other hand, I'm going to create a second RAID. 16 00:00:31,828 --> 00:00:32,661 This is going to be a RAID 1, 17 00:00:32,661 --> 00:00:34,310 which allows us to have two hard disks 18 00:00:34,310 --> 00:00:35,750 operating in a mirror. 19 00:00:35,750 --> 00:00:38,569 So, both disks are going to have exactly the same data on 'em. 20 00:00:38,569 --> 00:00:40,930 This means I'm not going to get the performance boost 21 00:00:40,930 --> 00:00:42,240 I get with a RAID 0, 22 00:00:42,240 --> 00:00:43,840 but I do get redundancy. 23 00:00:43,840 --> 00:00:44,860 So, if one disk fails, 24 00:00:44,860 --> 00:00:47,070 the other disk is still going to be maintaining 25 00:00:47,070 --> 00:00:49,046 a fully online and ready to use copy 26 00:00:49,046 --> 00:00:51,129 of all of the data and information. 27 00:00:51,129 --> 00:00:53,590 Now, let's go ahead and jump into the lab, 28 00:00:53,590 --> 00:00:56,490 and let me show you how to create these two types of RAIDs. 29 00:00:56,490 --> 00:00:58,040 So, on this Windows 10 machine, 30 00:00:58,040 --> 00:00:59,270 I current have a C drive 31 00:00:59,270 --> 00:01:00,900 with the operating system installed, 32 00:01:00,900 --> 00:01:03,490 and I have four blank disks that have been installed. 33 00:01:03,490 --> 00:01:04,887 I'm going to go ahead and go to my disk management, 34 00:01:04,887 --> 00:01:07,890 and inside my disk management, under computer management, 35 00:01:07,890 --> 00:01:10,680 you will see that I have four disks that are brand new. 36 00:01:10,680 --> 00:01:12,467 I'm going to go ahead and initialize those. 37 00:01:12,467 --> 00:01:14,830 Now that I've initialized them, 38 00:01:14,830 --> 00:01:16,918 I have these four unallocated disks 39 00:01:16,918 --> 00:01:20,760 sitting here at the bottom, and my current C drive. 40 00:01:20,760 --> 00:01:22,000 So, what I want to do is, 41 00:01:22,000 --> 00:01:24,340 I want to create two different RAIDs. 42 00:01:24,340 --> 00:01:26,320 I'm going to create one for video editing, 43 00:01:26,320 --> 00:01:29,188 which means I want performance over redundancy. 44 00:01:29,188 --> 00:01:30,240 So, what I'm going to do is, 45 00:01:30,240 --> 00:01:32,100 I'm going to right click on my first disk, 46 00:01:32,100 --> 00:01:34,370 and go to new striped volume. 47 00:01:34,370 --> 00:01:37,068 Because, I'm going to stripe across disk one and disk two 48 00:01:37,068 --> 00:01:40,490 to make my RAID 0, to give me that performance I want. 49 00:01:40,490 --> 00:01:41,900 As I walk through the wizard, 50 00:01:41,900 --> 00:01:43,520 I'm going to add the second disk to it. 51 00:01:43,520 --> 00:01:44,929 So, I have disk one and disk two, 52 00:01:44,929 --> 00:01:47,660 then I'm going to go down next, 53 00:01:47,660 --> 00:01:49,070 I'm going to give it a drive letter. 54 00:01:49,070 --> 00:01:51,960 In this case, I'm just going to go ahead and call it drive D. 55 00:01:51,960 --> 00:01:52,793 Hit next. 56 00:01:52,793 --> 00:01:53,740 I'm going to give it a name. 57 00:01:53,740 --> 00:01:54,790 I'm going to call it editing, 58 00:01:54,790 --> 00:01:56,590 because I'm going to use it for video editing. 59 00:01:56,590 --> 00:01:58,110 And then, I'll hit next. 60 00:01:58,110 --> 00:01:59,490 And then, we'll finish. 61 00:01:59,490 --> 00:02:01,010 And, we'll say yes, 62 00:02:01,010 --> 00:02:01,860 and off it goes. 63 00:02:01,860 --> 00:02:06,860 I now have, drive D, which is 1.57 terabytes, 64 00:02:07,150 --> 00:02:08,260 and I have 100% free, 65 00:02:08,260 --> 00:02:10,790 because I have two, 800 gigabyte drives 66 00:02:10,790 --> 00:02:13,060 working in tandem to give me 67 00:02:13,060 --> 00:02:15,960 that one, logical drive, drive D. 68 00:02:15,960 --> 00:02:18,060 But, if either of those disks fails, 69 00:02:18,060 --> 00:02:19,780 drive D will be gone. 70 00:02:19,780 --> 00:02:22,320 Now, let's go ahead and create a redundant drive, 71 00:02:22,320 --> 00:02:24,250 which is going to be drive three and four. 72 00:02:24,250 --> 00:02:27,060 I'm going to add them together as a mirrored volume. 73 00:02:27,060 --> 00:02:28,649 Now, when I add both of those in, 74 00:02:28,649 --> 00:02:30,550 I'm going to get two disks, 75 00:02:30,550 --> 00:02:33,330 but I'm only going to get one disk's worth of space. 76 00:02:33,330 --> 00:02:35,238 I'm going to call this R for redundancy. 77 00:02:35,238 --> 00:02:39,543 And so, over here for R, I'm going to call it redundant, 78 00:02:41,000 --> 00:02:43,090 and we'll go ahead and format it. 79 00:02:43,090 --> 00:02:47,080 And notice, I now have this redundant drive, 80 00:02:47,080 --> 00:02:48,868 which is called drive R. 81 00:02:48,868 --> 00:02:51,860 And, drive R is a mirrored drive, 82 00:02:51,860 --> 00:02:53,200 it is going to be dynamic. 83 00:02:53,200 --> 00:02:55,760 And you'll notice that it only has a capacity size 84 00:02:55,760 --> 00:02:57,410 of one of those drives, 85 00:02:57,410 --> 00:02:58,746 because one is acting as primary 86 00:02:58,746 --> 00:03:01,840 and one is acting as backup, where both of them 87 00:03:01,840 --> 00:03:03,550 have the exact same information. 88 00:03:03,550 --> 00:03:05,089 And, if either of them goes offline, 89 00:03:05,089 --> 00:03:07,970 the other drive will still take over. 90 00:03:07,970 --> 00:03:09,950 That gives me my fault tolerance, 91 00:03:09,950 --> 00:03:12,460 and that creates a 50% overhead, 92 00:03:12,460 --> 00:03:15,100 or a loss of one drive's worth of space. 93 00:03:15,100 --> 00:03:16,638 But, that's the sacrifice. 94 00:03:16,638 --> 00:03:19,890 Do you want performance, and double the space? 95 00:03:19,890 --> 00:03:23,260 Or, do you want redundancy, and half the space? 96 00:03:23,260 --> 00:03:25,160 That's the choice that we're making here. 97 00:03:25,160 --> 00:03:26,790 Now, in my case I chose both. 98 00:03:26,790 --> 00:03:28,730 I wanted one drive as my scratch drive 99 00:03:28,730 --> 00:03:29,690 for all my video editing, 100 00:03:29,690 --> 00:03:31,640 and I wanted my redundant drive to be 101 00:03:31,640 --> 00:03:33,270 where I store the finished products, 102 00:03:33,270 --> 00:03:36,238 and it gives me that redundancy that I was looking for. 103 00:03:36,238 --> 00:03:38,677 (electronic music)
