1 00:00:00,000 --> 00:00:02,009 In this demonstration, you're going to learn how 2 00:00:02,009 --> 00:00:04,890 to create a software RAID on a Windows machine. 3 00:00:04,890 --> 00:00:07,650 My machine has a few hard drives, and we're going to go ahead 4 00:00:07,650 --> 00:00:09,600 and use the Windows disk management tool 5 00:00:09,600 --> 00:00:12,000 to set up two different RAID systems on it. 6 00:00:12,000 --> 00:00:13,860 Now, one is going to be a RAID 0, 7 00:00:13,860 --> 00:00:16,170 which is going to provide us with more speed and performance 8 00:00:16,170 --> 00:00:18,120 by splitting the data being read and write 9 00:00:18,120 --> 00:00:20,970 into two separate drives on two different disks. 10 00:00:20,970 --> 00:00:23,280 Now, each disk is going to get half of the data. 11 00:00:23,280 --> 00:00:24,960 This means if I lose one of the drives, 12 00:00:24,960 --> 00:00:27,180 I'm going to lose all of the data. 13 00:00:27,180 --> 00:00:30,000 Now, on the other hand, I'm going to create a second RAID. 14 00:00:30,000 --> 00:00:31,350 This is going to be a RAID 1, 15 00:00:31,350 --> 00:00:33,510 which allows us to have two hard disks 16 00:00:33,510 --> 00:00:34,920 operating in a mirror. 17 00:00:34,920 --> 00:00:38,340 So both disks are going to have exactly the same data on. 18 00:00:38,340 --> 00:00:40,350 this means I'm not going to get the performance boost I get 19 00:00:40,350 --> 00:00:43,020 with a RAID 0, but I do get redundancy. 20 00:00:43,020 --> 00:00:44,370 So if one disk fails, 21 00:00:44,370 --> 00:00:47,310 the other disk is still going to be maintaining a fully online 22 00:00:47,310 --> 00:00:50,910 and ready to use copy of all of the data and information. 23 00:00:50,910 --> 00:00:52,770 Now, let's go ahead and jump into the lab 24 00:00:52,770 --> 00:00:55,650 and let me show you how to create these two types of RAIDs. 25 00:00:55,650 --> 00:00:58,440 So on this Windows 10 machine, I currently have a C drive 26 00:00:58,440 --> 00:01:00,180 with the operating system installed, 27 00:01:00,180 --> 00:01:02,640 and I have four blank disks that have been installed. 28 00:01:02,640 --> 00:01:04,680 Let me go ahead and go to my disk management 29 00:01:04,680 --> 00:01:07,050 and inside my disk management, under computer management, 30 00:01:07,050 --> 00:01:09,840 you'll see that I have four disks that are brand new. 31 00:01:09,840 --> 00:01:12,003 I'm going to go ahead and initialize those. 32 00:01:12,840 --> 00:01:13,980 Now, that I've initialized them 33 00:01:13,980 --> 00:01:16,920 I have these four unallocated disks sitting here 34 00:01:16,920 --> 00:01:19,950 at the bottom and my current C drive. 35 00:01:19,950 --> 00:01:21,180 So what I want to do is 36 00:01:21,180 --> 00:01:23,490 I want to create two different RAIDs. 37 00:01:23,490 --> 00:01:25,500 I'm going to create one for video editing, 38 00:01:25,500 --> 00:01:28,740 which means I want performance over redundancy. 39 00:01:28,740 --> 00:01:30,180 So what I'm going to do is I'm going to right click 40 00:01:30,180 --> 00:01:31,290 on my first disk 41 00:01:31,290 --> 00:01:33,540 and go to new striped volume 42 00:01:33,540 --> 00:01:36,600 because I'm going to stripe across Disk 1 and Disk 2 43 00:01:36,600 --> 00:01:39,660 to make my RAID 0 to give me that performance I want. 44 00:01:39,660 --> 00:01:41,070 As I walk through the wizard, 45 00:01:41,070 --> 00:01:42,690 I'm going to add the second disk to it 46 00:01:42,690 --> 00:01:45,000 so I have Disk 1 and Disk 2. 47 00:01:45,000 --> 00:01:46,830 Then I'm going to go down Next, 48 00:01:46,830 --> 00:01:48,210 I'm going to give it a drive letter. 49 00:01:48,210 --> 00:01:50,397 In this case, I'm just going to go ahead 50 00:01:50,397 --> 00:01:51,930 and call it drive D, hit Next. 51 00:01:51,930 --> 00:01:52,890 I'm going to give it a name 52 00:01:52,890 --> 00:01:53,970 and I'm going to call it editing 53 00:01:53,970 --> 00:01:55,770 because I'm going to use it for video editing 54 00:01:55,770 --> 00:01:57,270 and then I'll hit Next. 55 00:01:57,270 --> 00:01:58,800 and then we'll finish, 56 00:01:58,800 --> 00:02:01,020 and we'll say Yes and off it goes. 57 00:02:01,020 --> 00:02:06,020 I now have drive D, which is 1.57 terabytes, 58 00:02:06,300 --> 00:02:07,440 and I have a hundred percent free 59 00:02:07,440 --> 00:02:10,470 because I have two 800 gigabyte drives 60 00:02:10,470 --> 00:02:13,980 working in tandem to give me that one logical drive, 61 00:02:13,980 --> 00:02:15,120 drive D. 62 00:02:15,120 --> 00:02:18,960 But if either of those disk fails, drive D will be gone. 63 00:02:18,960 --> 00:02:21,480 Now, let's go ahead and create a redundant drive, 64 00:02:21,480 --> 00:02:23,400 which is going to be drive three and four. 65 00:02:23,400 --> 00:02:26,250 I'm going to add them together as a mirrored volume. 66 00:02:26,250 --> 00:02:29,730 Now, when I add both of those in, I'm going to get two disks 67 00:02:29,730 --> 00:02:32,490 but I'm only going to get one disk's worth of space 68 00:02:32,490 --> 00:02:35,190 and I'm going to call this R for redundancy. 69 00:02:35,190 --> 00:02:36,900 And so over here for R, 70 00:02:36,900 --> 00:02:38,620 I'm going to call it redundant 71 00:02:40,170 --> 00:02:42,240 and we'll go ahead and format it. 72 00:02:42,240 --> 00:02:46,230 And notice I now have this redundant drive, 73 00:02:46,230 --> 00:02:47,733 which is called drive R, 74 00:02:48,820 --> 00:02:51,030 drive R is a mirror drive. 75 00:02:51,030 --> 00:02:53,700 It is going to be dynamic, and you'll notice that it only 76 00:02:53,700 --> 00:02:56,580 has the capacity size of one of those drives 77 00:02:56,580 --> 00:02:58,230 because one is acting as primary 78 00:02:58,230 --> 00:02:59,850 and one is acting as backup 79 00:02:59,850 --> 00:03:02,700 where both of them have the exact same information. 80 00:03:02,700 --> 00:03:04,800 And if either of them goes offline, 81 00:03:04,800 --> 00:03:07,140 the other drive will still take over, 82 00:03:07,140 --> 00:03:09,240 that gives me my fault tolerance 83 00:03:09,240 --> 00:03:11,610 and that creates a 50% overhead 84 00:03:11,610 --> 00:03:14,280 or a loss of one drive's worth of space. 85 00:03:14,280 --> 00:03:16,140 But that's the sacrifice, 86 00:03:16,140 --> 00:03:19,050 do you want performance and double the space 87 00:03:19,050 --> 00:03:22,440 or do you want redundancy in half the space? 88 00:03:22,440 --> 00:03:24,330 That's the choice that we're making here. 89 00:03:24,330 --> 00:03:25,920 Now, in my case, I chose both. 90 00:03:25,920 --> 00:03:27,900 I wanted One drive as my scratch drive 91 00:03:27,900 --> 00:03:29,040 for all my video editing 92 00:03:29,040 --> 00:03:30,600 and I wanted my redundant drive 93 00:03:30,600 --> 00:03:32,490 to be where I store the finished products 94 00:03:32,490 --> 00:03:35,240 and it gives me that redundancy that I was looking for.
