Linus Tech tips coverage of computex 2013 is powered by Western Digital our

00:00:04.799 --> 00:00:11.040
trusted gaming gear partner is Corsair Vengeance and our trusted retail partner

00:00:08.840 --> 00:00:11.040
is

00:00:12.200 --> 00:00:17.080
nc.com is day four of computex and we're

00:00:15.400 --> 00:00:21.480
kicking it off at our home base here in the WD Booth this is the red drive a

00:00:19.560 --> 00:00:24.680
consumer grade Drive suitable for applications where you have anywhere

00:00:22.920 --> 00:00:29.560
from 1 to five drives in a raid environment it only comes in up to 3

00:00:26.640 --> 00:00:32.840
terab capacities though okay so what if you have something like this that

00:00:30.840 --> 00:00:37.280
accepts 10 drives what if you have something like this that's just begging

00:00:34.760 --> 00:00:40.120
to have six drives installed in it what if you need four terabyte drives well

00:00:39.079 --> 00:00:46.079
all of a sudden you're going to be looking at the

00:00:42.160 --> 00:00:47.840
wdsc scalable capacity as well as Data

00:00:46.079 --> 00:00:52.800
Center capacity so what what the heck does that even mean so number one is for

00:00:50.399 --> 00:00:58.519
high-end consumers you can use a desktop Naz like this number two is that because

00:00:55.160 --> 00:01:00.039
it shares so much DNA from the re Drive

00:00:58.519 --> 00:01:04.720
the rate Edition Drive the more traditional Enterprise Drive it is

00:01:02.399 --> 00:01:10.560
suitable for applications such as cloud storage so technology it's got a dual

00:01:08.880 --> 00:01:14.880
stage actuator which basically amounts to the Head being able to read data off

00:01:12.360 --> 00:01:20.600
of it more accurately so this is good it has raft technology and which basically

00:01:17.560 --> 00:01:22.600
amounts to it being less susceptible to

00:01:20.600 --> 00:01:27.920
vibrations from other drives causing performance degradation it has tle which

00:01:25.759 --> 00:01:33.119
allows it to not drop out of raid arrays even in well difficult ult circumstances

00:01:31.040 --> 00:01:37.320
and last but not least it has stable track technology which makes it less

00:01:34.880 --> 00:01:41.799
likely to transmit vibrations to other drives all of these things are optimized

00:01:39.680 --> 00:01:45.880
for multi-drive configurations so let's head over here where we're talking about

00:01:43.560 --> 00:01:50.159
a pretty serious multi-drive configuration in this kind of an

00:01:47.799 --> 00:01:55.840
application traditionally they would have deployed an re or Raid Edition

00:01:52.880 --> 00:02:02.399
Drive where it's got a 1.4 million hour meantime between failure it is extremely

00:01:58.200 --> 00:02:05.880
robust it is rated for 247 365 operation

00:02:02.399 --> 00:02:09.080
with a 100% duty cycle but if your

00:02:05.880 --> 00:02:10.959
Google Drive for example not all of this

00:02:09.080 --> 00:02:16.000
data is going to be necessarily accessed all the time so a 50% duty cycle might

00:02:13.680 --> 00:02:20.840
be okay that happens to be what the SE rated for also these customers who are

00:02:18.959 --> 00:02:27.319
storing their pictures or whatever else they're they're not going to be accessing it necessarily you know nearly

00:02:24.680 --> 00:02:32.319
as much so an 800,000 hour meantime between failure might also be okay and

00:02:29.920 --> 00:02:36.440
last but not least because these cloud storage applications are moving away

00:02:34.040 --> 00:02:42.200
from being so dependent on raid and moving more towards redundancy as

00:02:39.519 --> 00:02:46.760
opposed to and and replication as opposed to complicated raid controllers

00:02:45.159 --> 00:02:53.400
all of a sudden we're in a situation where if a drive suddenly dies you might

00:02:50.040 --> 00:02:54.800
have time to at your leisure replace it

00:02:53.400 --> 00:02:59.400
because you know that that data is replicated in a couple of other places

00:02:57.000 --> 00:03:04.599
so customers such as cloud storage companies who don't need the the

00:03:01.480 --> 00:03:06.879
robustness of an re but want capacity

00:03:04.599 --> 00:03:10.560
might lean towards an SE because it sits in between the red and the re in terms

00:03:08.640 --> 00:03:14.239
of pricing meaning you can get that capacity you need you get that build

00:03:12.440 --> 00:03:19.159
quality you need but you can save a little bit as well but what if you don't

00:03:16.920 --> 00:03:25.000
need the maximum in capacity and you'd rather have the maximum in performance

00:03:21.519 --> 00:03:27.159
this is the WD XE this is a SAS Drive

00:03:25.000 --> 00:03:31.959
optimized for as you may or may not have guessed already based on what I just

00:03:29.120 --> 00:03:35.799
said maximum performance it's a 2 and 1 half inch Drive which contributes to a

00:03:33.680 --> 00:03:39.760
couple of cool things number one is that it gives it outstanding random read and

00:03:37.640 --> 00:03:43.760
right performance because physically the heads don't have to move as far to read

00:03:41.840 --> 00:03:47.799
data off of the platter number two is that it contributes to power savings you

00:03:45.879 --> 00:03:53.640
can actually run these drives with an up to 67% power reduction compared to a 3

00:03:51.280 --> 00:03:58.120
and 1/2 in equivalent now there are some caveats um okay so you got compatibility

00:03:56.040 --> 00:04:04.599
with 2 and 1/2 in or 3 and 1/2 in dri sleds but you are still at a maximum

00:04:00.840 --> 00:04:07.000
capacity of 900 GB per drive for a

00:04:04.599 --> 00:04:12.439
deployment like this so it's pretty much well there you go there's SE and re for

00:04:10.079 --> 00:04:16.600
maximum storage space and maximum robustness and then there's XE if you

00:04:14.840 --> 00:04:21.560
don't care quite as much about those things as well as much about storage

00:04:19.000 --> 00:04:25.479
space but you want maximum performance and the robustness of the drive is

00:04:23.919 --> 00:04:30.720
actually better than either of the other two as well with a two million hour

00:04:28.240 --> 00:04:35.080
