1
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

2
00:00:04,120 --> 00:00:12,960
think Samsung has done anything visually interesting to their SSD lineup since

3
00:00:08,679 --> 00:00:17,039
they ever so why would we make a video

4
00:00:12,960 --> 00:00:19,760
about the 850 Pro well because we've got

5
00:00:17,039 --> 00:00:19,760
four of

6
00:00:21,320 --> 00:00:27,130
them also there's some really cool technology in them that I think is worth

7
00:00:25,119 --> 00:00:32,399
talking about

8
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

9
00:00:36,680 --> 00:00:43,039
to 3,333 MHz available click now to learn

10
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

11
00:00:46,440 --> 00:00:53,600
the scenes look at what we're using for the storage for the server that hosts

12
00:00:51,000 --> 00:00:58,960
the linch tips.com community forum and more importantly why we made that choice

13
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

14
00:01:02,039 --> 00:01:10,840
drives the introduction of the 850 Pro marked the first retail availability of

15
00:01:07,119 --> 00:01:12,360
a drive using vertical or 3D nand this

16
00:01:10,840 --> 00:01:17,280
comes with a couple of significant benefits so typically the way that flash

17
00:01:14,880 --> 00:01:22,880
and microprocessors get cheaper over time is that after significant research

18
00:01:19,960 --> 00:01:28,600
and expense clever folks like Intel and Samsung move to smaller and smaller

19
00:01:26,159 --> 00:01:33,920
manufacturing processes to allow them to build the same device with less raw

20
00:01:30,960 --> 00:01:37,560
material or more advanced devices with the same amount of raw material

21
00:01:35,759 --> 00:01:42,240
increasing performance and lowering overall costs in the long run the

22
00:01:39,920 --> 00:01:48,360
problem with this is that for Flash in particular as it gets more and more

23
00:01:44,560 --> 00:01:50,719
dense its performance drops and so does

24
00:01:48,360 --> 00:01:55,840
its endurance the number of times it can be written to before it's not reliable

25
00:01:53,320 --> 00:02:01,320
anymore so for several generations of ssds much of the performance and

26
00:01:58,920 --> 00:02:07,079
warranty Improvement that we've seen has been from among other things SSD

27
00:02:04,039 --> 00:02:09,520
manufacturers finding ways of using wear

28
00:02:07,079 --> 00:02:14,360
leveling to cleverly spread the load out across all the chips in a drive or even

29
00:02:12,000 --> 00:02:17,720
making the best use of limited flash performance with voodoo magic like on

30
00:02:16,360 --> 00:02:22,760
thefly data compression and decompression but now here comes

31
00:02:20,160 --> 00:02:26,800
vertical Nan to the rescue so by stacking layers instead of spreading

32
00:02:24,680 --> 00:02:31,400
them out two dimensionally Samsung can achieve the density and therefore

33
00:02:29,239 --> 00:02:36,879
capacity that they need these are one tab drives we're using while using a

34
00:02:34,160 --> 00:02:42,560
bigger manufacturing process this ends up using nearly the same raw material in

35
00:02:39,680 --> 00:02:47,480
manufacturing but gives back some of the performance and reliability that

36
00:02:44,920 --> 00:02:53,239
advanced SSD controllers have been compensating for over the last few years

37
00:02:50,440 --> 00:02:59,879
with the voodoo magic I mentioned before Samsung then turns around and pairs this

38
00:02:56,120 --> 00:03:01,720
faster more reliable flash with a modern

39
00:02:59,879 --> 00:03:08,120
Advanced Three core controller and up to a gig of low power ddr2 for cash and

40
00:03:04,720 --> 00:03:11,440
voila the 50 Pro is about as fast as a

41
00:03:08,120 --> 00:03:14,879
SATA 3 SSD can be while being rated even

42
00:03:11,440 --> 00:03:17,159
at its lowest capacity to handle 40 gigs

43
00:03:14,879 --> 00:03:22,400
per day of Rights for the entire duration of its 10-year warranty which

44
00:03:19,440 --> 00:03:28,920
isn't merely as impressive as the 128 gig Drive Samsung says they've had in

45
00:03:24,400 --> 00:03:31,439
their lab for uh over 8,000 terabytes of

46
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

47
00:03:32,840 --> 00:03:38,360
support for Rapid their SSD acceleration

48
00:03:36,080 --> 00:03:41,680
with sort of RAM cache thing that can be enabled through the SSD magician

49
00:03:39,799 --> 00:03:46,959
monitoring and tweaking utility full drive encryption support and Samsung's

50
00:03:43,560 --> 00:03:49,120
easy to use cloning software so all of

51
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

52
00:03:51,400 --> 00:03:58,040
we're running Western Digital re series Enterprise grade hard drives for the

53
00:03:55,840 --> 00:04:01,680
Forum software and the database and we've discovered some interesting issues

54
00:03:59,799 --> 00:04:07,480
isues especially when we launch giveaways and contests in spite of CPU

55
00:04:05,280 --> 00:04:15,000
load being quite manageable we've been getting some weird issues

56
00:04:11,599 --> 00:04:18,840
oops okay I'mma put these boxes here

57
00:04:15,000 --> 00:04:20,199
where they'll be safe sort of um back on

58
00:04:18,840 --> 00:04:24,639
topic so we've discovered some interesting issues whenever we launch

59
00:04:22,040 --> 00:04:29,919
giveaways and contests in spite of pretty manageable CPU load we've been

60
00:04:27,720 --> 00:04:33,600
getting some weird issues with errors during account creation as people are

61
00:04:31,880 --> 00:04:39,000
rushing to make accounts and join these giveaways and we narrowed that down to a

62
00:04:35,880 --> 00:04:41,479
storage performance limitation so that

63
00:04:39,000 --> 00:04:46,639
is where the 850 pros come in starting when these get deployed the entire Linus

64
00:04:43,840 --> 00:04:50,759
Tech tips.com site will be solid state based we know that while unlike

65
00:04:48,680 --> 00:04:55,960
Samsung's Enterprise grade Solutions these prosumer drives don't offer ENT to

66
00:04:53,840 --> 00:05:01,120
end data protection or power loss protection but our system uses a battery

67
00:04:58,960 --> 00:05:05,639
backup to protect against unexpected shutdowns and having data loss due to

68
00:05:03,160 --> 00:05:09,919
that so we're willing to risk using consumer grade Hardware um in order to

69
00:05:08,039 --> 00:05:14,680
get the raw performance and reliability that we'll get with 850 Pros as well as

70
00:05:12,479 --> 00:05:19,600
the capacity and price so sort of balancing all those things now in the

71
00:05:17,080 --> 00:05:23,919
server we'll be using our four drives responsibly one will be for the

72
00:05:21,400 --> 00:05:28,199
operating system two will be for the database in a raid one setup for

73
00:05:25,960 --> 00:05:34,400
protection from Hardware failure and a fourth will be a periodic manual copy

74
00:05:32,240 --> 00:05:39,319
from The Raid one so actually triple redundancy but since we had Samsung send

75
00:05:37,080 --> 00:05:43,039
the drives to us to forward to the data center we figured why not see exactly

76
00:05:41,520 --> 00:05:51,080
how much performance could be extracted from them if we decided to go crazy and

77
00:05:45,880 --> 00:05:54,240
build a 4 tbte raid zero array the

78
00:05:51,080 --> 00:05:56,600
answer is well over 1 GB per second and

79
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

80
00:06:00,240 --> 00:06:06,120
one thing that disappointed me a little bit here nothing to do with the drives

81
00:06:04,400 --> 00:06:10,319
is that while they're capable of much more than this it looks like Intel's

82
00:06:08,120 --> 00:06:16,520
onboard RAID controller is still a bottleneck for such a high throughput

83
00:06:13,199 --> 00:06:17,960
configuration even on x99 the good news

84
00:06:16,520 --> 00:06:23,120
is that for people running more reasonable two or three Drive raid zero

85
00:06:20,800 --> 00:06:26,880
configs Intel's raid driver passes through the trim command to keep it

86
00:06:24,479 --> 00:06:31,599
running at Peak efficiency so aside from the reliability concerns of raid zero

87
00:06:29,160 --> 00:06:36,360
remember one drive fails all the array data is lost it's a somewhat viable

88
00:06:34,199 --> 00:06:40,800
configuration for SSD users that allows them to overcome the bottleneck that is

89
00:06:38,319 --> 00:06:43,840
the SATA 3 interface until they bump up against the next bottleneck in the

90
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

91
00:06:46,680 --> 00:06:52,360
else the case may be anyway this was fun

92
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

93
00:06:54,039 --> 00:06:58,440
delivering you guys even better website performance and if you haven't checked

94
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

95
00:07:00,319 --> 00:07:07,680
