00:00:00.040 --> 00:00:06.680
we don't often do videos about ssds anymore I mean look at them I don't

00:00:04.120 --> 00:00:12.960
think Samsung has done anything visually interesting to their SSD lineup since

00:00:08.679 --> 00:00:17.039
they ever so why would we make a video

00:00:12.960 --> 00:00:19.760
about the 850 Pro well because we've got

00:00:17.039 --> 00:00:19.760
four of

00:00:21.320 --> 00:00:27.130
them also there's some really cool technology in them that I think is worth

00:00:25.119 --> 00:00:32.399
talking about

00:00:32.399 --> 00:00:37.520
d skill's new rip Jaws 4 Series is their ultimate ddr4 memory with speeds of up

00:00:36.680 --> 00:00:43.039
to 3,333 MHz available click now to learn

00:00:40.559 --> 00:00:49.120
more no but seriously this video isn't meant to be so much a review as a behind

00:00:46.440 --> 00:00:53.600
the scenes look at what we're using for the storage for the server that hosts

00:00:51.000 --> 00:00:58.960
the linch tips.com community forum and more importantly why we made that choice

00:00:57.199 --> 00:01:04.360
now a huge part of the story here is the Nan Flash actual storage chips on the

00:01:02.039 --> 00:01:10.840
drives the introduction of the 850 Pro marked the first retail availability of

00:01:07.119 --> 00:01:12.360
a drive using vertical or 3D nand this

00:01:10.840 --> 00:01:17.280
comes with a couple of significant benefits so typically the way that flash

00:01:14.880 --> 00:01:22.880
and microprocessors get cheaper over time is that after significant research

00:01:19.960 --> 00:01:28.600
and expense clever folks like Intel and Samsung move to smaller and smaller

00:01:26.159 --> 00:01:33.920
manufacturing processes to allow them to build the same device with less raw

00:01:30.960 --> 00:01:37.560
material or more advanced devices with the same amount of raw material

00:01:35.759 --> 00:01:42.240
increasing performance and lowering overall costs in the long run the

00:01:39.920 --> 00:01:48.360
problem with this is that for Flash in particular as it gets more and more

00:01:44.560 --> 00:01:50.719
dense its performance drops and so does

00:01:48.360 --> 00:01:55.840
its endurance the number of times it can be written to before it's not reliable

00:01:53.320 --> 00:02:01.320
anymore so for several generations of ssds much of the performance and

00:01:58.920 --> 00:02:07.079
warranty Improvement that we've seen has been from among other things SSD

00:02:04.039 --> 00:02:09.520
manufacturers finding ways of using wear

00:02:07.079 --> 00:02:14.360
leveling to cleverly spread the load out across all the chips in a drive or even

00:02:12.000 --> 00:02:17.720
making the best use of limited flash performance with voodoo magic like on

00:02:16.360 --> 00:02:22.760
thefly data compression and decompression but now here comes

00:02:20.160 --> 00:02:26.800
vertical Nan to the rescue so by stacking layers instead of spreading

00:02:24.680 --> 00:02:31.400
them out two dimensionally Samsung can achieve the density and therefore

00:02:29.239 --> 00:02:36.879
capacity that they need these are one tab drives we're using while using a

00:02:34.160 --> 00:02:42.560
bigger manufacturing process this ends up using nearly the same raw material in

00:02:39.680 --> 00:02:47.480
manufacturing but gives back some of the performance and reliability that

00:02:44.920 --> 00:02:53.239
advanced SSD controllers have been compensating for over the last few years

00:02:50.440 --> 00:02:59.879
with the voodoo magic I mentioned before Samsung then turns around and pairs this

00:02:56.120 --> 00:03:01.720
faster more reliable flash with a modern

00:02:59.879 --> 00:03:08.120
Advanced Three core controller and up to a gig of low power ddr2 for cash and

00:03:04.720 --> 00:03:11.440
voila the 50 Pro is about as fast as a

00:03:08.120 --> 00:03:14.879
SATA 3 SSD can be while being rated even

00:03:11.440 --> 00:03:17.159
at its lowest capacity to handle 40 gigs

00:03:14.879 --> 00:03:22.400
per day of Rights for the entire duration of its 10-year warranty which

00:03:19.440 --> 00:03:28.920
isn't merely as impressive as the 128 gig Drive Samsung says they've had in

00:03:24.400 --> 00:03:31.439
their lab for uh over 8,000 terabytes of

00:03:28.920 --> 00:03:36.080
Rights and it just keeps going and then I guess on top of that you also get

00:03:32.840 --> 00:03:38.360
support for Rapid their SSD acceleration

00:03:36.080 --> 00:03:41.680
with sort of RAM cache thing that can be enabled through the SSD magician

00:03:39.799 --> 00:03:46.959
monitoring and tweaking utility full drive encryption support and Samsung's

00:03:43.560 --> 00:03:49.120
easy to use cloning software so all of

00:03:46.959 --> 00:03:53.760
that out of the way what are we using these for well right now in the server

00:03:51.400 --> 00:03:58.040
we're running Western Digital re series Enterprise grade hard drives for the

00:03:55.840 --> 00:04:01.680
Forum software and the database and we've discovered some interesting issues

00:03:59.799 --> 00:04:07.480
isues especially when we launch giveaways and contests in spite of CPU

00:04:05.280 --> 00:04:15.000
load being quite manageable we've been getting some weird issues

00:04:11.599 --> 00:04:18.840
oops okay I'mma put these boxes here

00:04:15.000 --> 00:04:20.199
where they'll be safe sort of um back on

00:04:18.840 --> 00:04:24.639
topic so we've discovered some interesting issues whenever we launch

00:04:22.040 --> 00:04:29.919
giveaways and contests in spite of pretty manageable CPU load we've been

00:04:27.720 --> 00:04:33.600
getting some weird issues with errors during account creation as people are

00:04:31.880 --> 00:04:39.000
rushing to make accounts and join these giveaways and we narrowed that down to a

00:04:35.880 --> 00:04:41.479
storage performance limitation so that

00:04:39.000 --> 00:04:46.639
is where the 850 pros come in starting when these get deployed the entire Linus

00:04:43.840 --> 00:04:50.759
Tech tips.com site will be solid state based we know that while unlike

00:04:48.680 --> 00:04:55.960
Samsung's Enterprise grade Solutions these prosumer drives don't offer ENT to

00:04:53.840 --> 00:05:01.120
end data protection or power loss protection but our system uses a battery

00:04:58.960 --> 00:05:05.639
backup to protect against unexpected shutdowns and having data loss due to

00:05:03.160 --> 00:05:09.919
that so we're willing to risk using consumer grade Hardware um in order to

00:05:08.039 --> 00:05:14.680
get the raw performance and reliability that we'll get with 850 Pros as well as

00:05:12.479 --> 00:05:19.600
the capacity and price so sort of balancing all those things now in the

00:05:17.080 --> 00:05:23.919
server we'll be using our four drives responsibly one will be for the

00:05:21.400 --> 00:05:28.199
operating system two will be for the database in a raid one setup for

00:05:25.960 --> 00:05:34.400
protection from Hardware failure and a fourth will be a periodic manual copy

00:05:32.240 --> 00:05:39.319
from The Raid one so actually triple redundancy but since we had Samsung send

00:05:37.080 --> 00:05:43.039
the drives to us to forward to the data center we figured why not see exactly

00:05:41.520 --> 00:05:51.080
how much performance could be extracted from them if we decided to go crazy and

00:05:45.880 --> 00:05:54.240
build a 4 tbte raid zero array the

00:05:51.080 --> 00:05:56.600
answer is well over 1 GB per second and

00:05:54.240 --> 00:06:01.960
here's some Crystal disc Mark and as SSD numbers for the SSD Geeks out there but

00:06:00.240 --> 00:06:06.120
one thing that disappointed me a little bit here nothing to do with the drives

00:06:04.400 --> 00:06:10.319
is that while they're capable of much more than this it looks like Intel's

00:06:08.120 --> 00:06:16.520
onboard RAID controller is still a bottleneck for such a high throughput

00:06:13.199 --> 00:06:17.960
configuration even on x99 the good news

00:06:16.520 --> 00:06:23.120
is that for people running more reasonable two or three Drive raid zero

00:06:20.800 --> 00:06:26.880
configs Intel's raid driver passes through the trim command to keep it

00:06:24.479 --> 00:06:31.599
running at Peak efficiency so aside from the reliability concerns of raid zero

00:06:29.160 --> 00:06:36.360
remember one drive fails all the array data is lost it's a somewhat viable

00:06:34.199 --> 00:06:40.800
configuration for SSD users that allows them to overcome the bottleneck that is

00:06:38.319 --> 00:06:43.840
the SATA 3 interface until they bump up against the next bottleneck in the

00:06:42.440 --> 00:06:50.400
system at which point it might be time to go m.2 or SATA Express or whatever

00:06:46.680 --> 00:06:52.360
else the case may be anyway this was fun

00:06:50.400 --> 00:06:56.199
while it lasted but it's time to send these to our Forum host so we can start

00:06:54.039 --> 00:06:58.440
delivering you guys even better website performance and if you haven't checked

00:06:57.280 --> 00:07:02.720
it out already you guys should head over to linch tips.com we've got a great

00:07:00.319 --> 00:07:07.680
