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

00:00:18.160 --> 00:00:25.279
WD red which is the original Nas optimized consumer grade hard drive and

00:00:23.000 --> 00:00:29.080
then we've got the newcomer the seate nas hard drive so what they both have

00:00:27.400 --> 00:00:35.120
going for them is longer warranty periods than a typical consumer grade

00:00:31.000 --> 00:00:38.360
device 247 tech support as well as a

00:00:35.120 --> 00:00:39.680
247 rated uh sort of operational

00:00:38.360 --> 00:00:43.719
workload that's that's what they're designed for to actually be used all the

00:00:41.440 --> 00:00:48.480
time in a storage Appliance they're both optimized for smaller rating closur so

00:00:46.440 --> 00:00:52.359
for example the red is good for anywhere from one to five Drive arrays and

00:00:50.680 --> 00:00:58.079
there's a reason for that because as much as I have always used just regular

00:00:55.239 --> 00:01:01.199
desktop drives in nases both seate and WD have lectured me about this because

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

00:01:05.439 --> 00:01:12.560
term particularly when you pile more and more drives into an enclosure so having

00:01:10.280 --> 00:01:17.320
drives that are optimized for resisting any errors that might be caused by that

00:01:14.439 --> 00:01:21.079
vibration is definitely a positive positive thing the one key difference

00:01:19.240 --> 00:01:24.119
between these drives is that the WD red does tend to be a little bit more

00:01:22.320 --> 00:01:28.799
expensive on retailer shelves and is only available in a 3 tab capacity up

00:01:26.079 --> 00:01:33.240
till now and performance of these drives in Nas enclosures is very much an

00:01:31.560 --> 00:01:39.040
unknown at this point not too many people have really looked into it so we

00:01:35.280 --> 00:01:42.399
decided to take a sonology ds411 so this

00:01:39.040 --> 00:01:44.320
is their disc station quad Bay enclosure

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

00:01:46.680 --> 00:01:52.719
four of the Seagate NAS drive 4 terabytes and decided to run some

00:01:50.759 --> 00:01:57.560
benchmarks because many people are looking at these NAS Drives going oh

00:01:54.360 --> 00:02:00.360
well they only run at 5400 or 5900 or

00:01:57.560 --> 00:02:04.680
whatever sort of Eco optimized RP M CU remember in a Naas enclosure you want

00:02:02.320 --> 00:02:07.600
less power consumption and you want less power consumption did I say power

00:02:06.399 --> 00:02:10.920
consumption twice because what I meant to say was heat output for the second

00:02:09.520 --> 00:02:14.840
thing you want less of both of those things so running at a lower RPM does

00:02:13.200 --> 00:02:19.400
help achieve that but what does that do to Performance well I'll tell you what

00:02:16.800 --> 00:02:24.040
we were expecting to happen is we were expecting the land interface right there

00:02:22.319 --> 00:02:28.080
that gigabit land interface to be the first bottleneck even running in

00:02:26.000 --> 00:02:32.720
something like a raid one configuration which is two Drive redundancy no

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

00:02:35.200 --> 00:02:42.000
100 megabytes perss transfer speeds if we're running in something like a raid

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

00:02:45.319 --> 00:02:51.519
which means that a 5900 RPM Drive can keep up just fine so the other

00:02:49.239 --> 00:02:56.040
bottleneck like I said in raid five is going to be internally here the

00:02:53.319 --> 00:02:59.840
processor raid five is very calculation intensive so basically what you do is

00:02:58.400 --> 00:03:04.599
you have at least three drives and one one of the drives worth of space is

00:03:02.120 --> 00:03:09.200
allocated for a parody bit which is pretty much a song that someone designs

00:03:06.840 --> 00:03:12.200
to sound like another song and then they actually Chang the lyrics to make it

00:03:10.640 --> 00:03:16.599
more comical no no not that kind of parody the real parody is data that can

00:03:14.799 --> 00:03:21.360
be used to reconstruct the data on the other drive so it's extremely

00:03:19.080 --> 00:03:26.239
computation intensive when it comes particularly to writing data to a r

00:03:23.280 --> 00:03:30.360
array anyway without further Ado I'm going to put some charts and graphs up

00:03:28.959 --> 00:03:34.560
on the screen that'll give you guys some idea of the performance differences we

00:03:32.000 --> 00:03:38.920
observed which I think really backs up our hypothesis in a very big way we ran

00:03:37.280 --> 00:03:43.319
several different tests including real world small medium and large file copy

00:03:41.400 --> 00:03:47.680
tests and all of these numbers are reported in the time it took to complete

00:03:45.640 --> 00:03:51.879
the operations with either different set of drives and then we also ran black

00:03:49.720 --> 00:03:55.680
Magic's dis speed test which we've found to be a fairly reproducible and just

00:03:53.920 --> 00:03:59.280
kind of a quick and dirty Benchmark so that gives you a synthetic Benchmark as

00:03:57.360 --> 00:04:03.120
well as a real world Benchmark to show you that we really didn't observe a

00:04:01.560 --> 00:04:07.280
difference in performance between these drives so with no real performance

00:04:05.560 --> 00:04:11.040
difference between the drives how do you pick which one to go with and I think

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

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

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

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

00:04:27.440 --> 00:04:35.039
to consider I know slick just recently purchased just four of the 3 terab WD

00:04:31.840 --> 00:04:36.280
Reds for a personal raid array um so

00:04:35.039 --> 00:04:40.320
that should give you some idea what we think of the red particularly internally

00:04:38.360 --> 00:04:44.680
here and speaking of things that we think very highly of internally here

00:04:42.039 --> 00:04:49.479

150,000 audiobooks that you can download now whether it's older stuff business

00:05:01.240 --> 00:05:07.600
stuff or the latest bestsellers so for example I was just checking out the

00:05:04.919 --> 00:05:12.600
Cuckoo's calling by Robert galra or grith or GTH whatever it doesn't matter

00:05:10.680 --> 00:05:16.440
not a real person um if you don't know this already Robert galbreth is actually

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

00:05:18.160 --> 00:05:25.280
all that it was very well reviewed but wasn't selling particularly well until

00:05:22.840 --> 00:05:28.880
all of a sudden it leaked and someone told someone who told someone and anyway

00:05:27.280 --> 00:05:33.720
the point is now it's all over the internet Al acclaimed even before we

00:05:31.440 --> 00:05:38.160
knew it was JK rling I'm receiving extremely good reviews even now that we

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

00:05:39.560 --> 00:05:44.360
mystery so no no magic or anything like

00:05:42.800 --> 00:05:50.960
that and I do recommend checking that out guys if you go ahead and redeem your

00:05:59.639 --> 00:06:04.400
