learn more Welcome to our NAS drive Roundup so we've got two contenders the

4
00:00:18,160 --> 00:00:25,279
WD red which is the original Nas optimized consumer grade hard drive and

5
00:00:23,000 --> 00:00:29,080
then we've got the newcomer the seate nas hard drive so what they both have

6
00:00:27,400 --> 00:00:35,120
going for them is longer warranty periods than a typical consumer grade

7
00:00:31,000 --> 00:00:38,360
device 247 tech support as well as a

8
00:00:35,120 --> 00:00:39,680
247 rated uh sort of operational

9
00:00:38,360 --> 00:00:43,719
workload that's that's what they're designed for to actually be used all the

10
00:00:41,440 --> 00:00:48,480
time in a storage Appliance they're both optimized for smaller rating closur so

11
00:00:46,440 --> 00:00:52,359
for example the red is good for anywhere from one to five Drive arrays and

12
00:00:50,680 --> 00:00:58,079
there's a reason for that because as much as I have always used just regular

13
00:00:55,239 --> 00:01:01,199
desktop drives in nases both seate and WD have lectured me about this because

14
00:01:00,160 --> 00:01:07,759
they're like well actually the vibrations that are passed between the drives um can be a problem in the longer

15
00:01:05,439 --> 00:01:12,560
term particularly when you pile more and more drives into an enclosure so having

16
00:01:10,280 --> 00:01:17,320
drives that are optimized for resisting any errors that might be caused by that

17
00:01:14,439 --> 00:01:21,079
vibration is definitely a positive positive thing the one key difference

18
00:01:19,240 --> 00:01:24,119
between these drives is that the WD red does tend to be a little bit more

19
00:01:22,320 --> 00:01:28,799
expensive on retailer shelves and is only available in a 3 tab capacity up

20
00:01:26,079 --> 00:01:33,240
till now and performance of these drives in Nas enclosures is very much an

21
00:01:31,560 --> 00:01:39,040
unknown at this point not too many people have really looked into it so we

22
00:01:35,280 --> 00:01:42,399
decided to take a sonology ds411 so this

23
00:01:39,040 --> 00:01:44,320
is their disc station quad Bay enclosure

24
00:01:42,399 --> 00:01:48,840
we set up a raid five in there with either four of the red 3 terabytes or

25
00:01:46,680 --> 00:01:52,719
four of the Seagate NAS drive 4 terabytes and decided to run some

26
00:01:50,759 --> 00:01:57,560
benchmarks because many people are looking at these NAS Drives going oh

27
00:01:54,360 --> 00:02:00,360
well they only run at 5400 or 5900 or

28
00:01:57,560 --> 00:02:04,680
whatever sort of Eco optimized RP M CU remember in a Naas enclosure you want

29
00:02:02,320 --> 00:02:07,600
less power consumption and you want less power consumption did I say power

30
00:02:06,399 --> 00:02:10,920
consumption twice because what I meant to say was heat output for the second

31
00:02:09,520 --> 00:02:14,840
thing you want less of both of those things so running at a lower RPM does

32
00:02:13,200 --> 00:02:19,400
help achieve that but what does that do to Performance well I'll tell you what

33
00:02:16,800 --> 00:02:24,040
we were expecting to happen is we were expecting the land interface right there

34
00:02:22,319 --> 00:02:28,080
that gigabit land interface to be the first bottleneck even running in

35
00:02:26,000 --> 00:02:32,720
something like a raid one configuration which is two Drive redundancy no

36
00:02:29,920 --> 00:02:37,959
calculations we are looking at about I mean we're looking at a maximum of 80 to

37
00:02:35,200 --> 00:02:42,000
100 megabytes perss transfer speeds if we're running in something like a raid

38
00:02:39,239 --> 00:02:47,400
five for rights we'll be lucky to get 25 to 35 megabytes per second right speeds

39
00:02:45,319 --> 00:02:51,519
which means that a 5900 RPM Drive can keep up just fine so the other

40
00:02:49,239 --> 00:02:56,040
bottleneck like I said in raid five is going to be internally here the

41
00:02:53,319 --> 00:02:59,840
processor raid five is very calculation intensive so basically what you do is

42
00:02:58,400 --> 00:03:04,599
you have at least three drives and one one of the drives worth of space is

43
00:03:02,120 --> 00:03:09,200
allocated for a parody bit which is pretty much a song that someone designs

44
00:03:06,840 --> 00:03:12,200
to sound like another song and then they actually Chang the lyrics to make it

45
00:03:10,640 --> 00:03:16,599
more comical no no not that kind of parody the real parody is data that can

46
00:03:14,799 --> 00:03:21,360
be used to reconstruct the data on the other drive so it's extremely

47
00:03:19,080 --> 00:03:26,239
computation intensive when it comes particularly to writing data to a r

48
00:03:23,280 --> 00:03:30,360
array anyway without further Ado I'm going to put some charts and graphs up

49
00:03:28,959 --> 00:03:34,560
on the screen that'll give you guys some idea of the performance differences we

50
00:03:32,000 --> 00:03:38,920
observed which I think really backs up our hypothesis in a very big way we ran

51
00:03:37,280 --> 00:03:43,319
several different tests including real world small medium and large file copy

52
00:03:41,400 --> 00:03:47,680
tests and all of these numbers are reported in the time it took to complete

53
00:03:45,640 --> 00:03:51,879
the operations with either different set of drives and then we also ran black

54
00:03:49,720 --> 00:03:55,680
Magic's dis speed test which we've found to be a fairly reproducible and just

55
00:03:53,920 --> 00:03:59,280
kind of a quick and dirty Benchmark so that gives you a synthetic Benchmark as

56
00:03:57,360 --> 00:04:03,120
well as a real world Benchmark to show you that we really didn't observe a

57
00:04:01,560 --> 00:04:07,280
difference in performance between these drives so with no real performance

58
00:04:05,560 --> 00:04:11,040
difference between the drives how do you pick which one to go with and I think

59
00:04:09,560 --> 00:04:16,479
the answer is that it comes down to trust who do you have the best experiences with over the longer term or

60
00:04:14,280 --> 00:04:20,280
the people you know or whatever else do you want to pay more for the WD or do

61
00:04:18,320 --> 00:04:24,240
you want to pay less for the Seagate or do you need the 4 tab capacity that's

62
00:04:22,400 --> 00:04:29,320
available in the seate WD doesn't have a 4 TB red yet so there's all those things

63
00:04:27,440 --> 00:04:35,039
to consider I know slick just recently purchased just four of the 3 terab WD

64
00:04:31,840 --> 00:04:36,280
Reds for a personal raid array um so

65
00:04:35,039 --> 00:04:40,320
that should give you some idea what we think of the red particularly internally

66
00:04:38,360 --> 00:04:44,680
here and speaking of things that we think very highly of internally here

71
00:05:01,240 --> 00:05:07,600
stuff or the latest bestsellers so for example I was just checking out the

72
00:05:04,919 --> 00:05:12,600
Cuckoo's calling by Robert galra or grith or GTH whatever it doesn't matter

73
00:05:10,680 --> 00:05:16,440
not a real person um if you don't know this already Robert galbreth is actually

74
00:05:14,479 --> 00:05:20,680
a pen name that was being used by JK Rowling so there's a big controversy and

75
00:05:18,160 --> 00:05:25,280
all that it was very well reviewed but wasn't selling particularly well until

76
00:05:22,840 --> 00:05:28,880
all of a sudden it leaked and someone told someone who told someone and anyway

77
00:05:27,280 --> 00:05:33,720
the point is now it's all over the internet Al acclaimed even before we

78
00:05:31,440 --> 00:05:38,160
knew it was JK rling I'm receiving extremely good reviews even now that we

79
00:05:36,160 --> 00:05:42,800
do know that it's JK rling who wrote this particular book so it's kind of a

80
00:05:39,560 --> 00:05:44,360
mystery so no no magic or anything like

81
00:05:42,800 --> 00:05:50,960
that and I do recommend checking that out guys if you go ahead and redeem your
