1
00:00:00,120 --> 00:00:06,960
a common piece of advice given to new computer tinkerers is that the single

2
00:00:04,680 --> 00:00:13,120
best upgrade you can give especially an older PC is a solid state drive or an

3
00:00:10,480 --> 00:00:18,359
SSD not only because this removes the hard drive bottleneck but also because

4
00:00:15,480 --> 00:00:23,480
in general any SSD is going to give you a significant performance boost even if

5
00:00:21,320 --> 00:00:26,960
you don't agonize for hours over the exact model you're going to buy and just

6
00:00:25,400 --> 00:00:33,079
end up spending 10 seconds picking out the highest rated one on Amazon but many

7
00:00:30,039 --> 00:00:35,719
many of you also have higher performance

8
00:00:33,079 --> 00:00:42,160
requirements than simply faster than a hard drive so today we're following up

9
00:00:39,079 --> 00:00:43,920
on our guide on which SSD to buy which

10
00:00:42,160 --> 00:00:48,280
you can check out here with an explanation of the different kinds of

11
00:00:45,960 --> 00:00:53,440
flash memory that you'll find not only in ssds but also in things like

12
00:00:50,640 --> 00:01:01,800
removable memory cards and USB thumb drives So currently SSD flash memory

13
00:00:57,480 --> 00:01:05,479
comes in a few main flavors s SLC mlc

14
00:01:01,800 --> 00:01:08,080
and TLC which you will sometimes find in

15
00:01:05,479 --> 00:01:13,799
the SSD product description but unfortunately not always which sucks

16
00:01:11,759 --> 00:01:22,439
because these three things could have a huge impact on the performance of your

17
00:01:16,080 --> 00:01:25,600
drive but how well the letter c c yeah

18
00:01:22,439 --> 00:01:29,640
that way in these variety stands for

19
00:01:25,600 --> 00:01:33,040
cell as in the memory cells in your ssds

20
00:01:29,640 --> 00:01:35,280
that store data so depending on the type

21
00:01:33,040 --> 00:01:40,799
each cell can hold a different number of bits that is the zeros and ones that

22
00:01:38,119 --> 00:01:47,840
make up all Digital Data a single level cell or SLC can hold just one bit per

23
00:01:44,280 --> 00:01:51,079
cell while triple level cells or TLC's

24
00:01:47,840 --> 00:01:53,759
can store three bits per cell NLC

25
00:01:51,079 --> 00:01:59,560
actually stands for multi-level cell so technically TLC is a subset but mlc is

26
00:01:56,640 --> 00:02:02,159
commonly used to refer to two bits per cell

27
00:02:00,360 --> 00:02:08,000
so it shouldn't be surprising then that TLC which can store the most bits per

28
00:02:04,640 --> 00:02:10,319
cell offers higher capacities in fact

29
00:02:08,000 --> 00:02:17,680
their higher data density also makes them cheaper per Gigabyte but there's a

30
00:02:14,000 --> 00:02:20,720
caveat here remember that ssds only last

31
00:02:17,680 --> 00:02:24,200
for a certain number of right cycles and

32
00:02:20,720 --> 00:02:26,720
since the electronics in TLC's requires

33
00:02:24,200 --> 00:02:33,200
more rights per sell because they store more they don't last as long as ml C's

34
00:02:30,519 --> 00:02:39,239
and slc's and they also tend to be significantly slower for these reasons

35
00:02:36,040 --> 00:02:42,840
you will mostly find TLC flash on

36
00:02:39,239 --> 00:02:46,200
lower-end ssds and portable storage

37
00:02:42,840 --> 00:02:49,319
devices instead most mainstream and

38
00:02:46,200 --> 00:02:51,879
higher-end consumer ssds these days use

39
00:02:49,319 --> 00:02:58,040
mlc Flash which represents a nice compromise between data density

40
00:02:54,319 --> 00:03:00,080
longevity performance and price these

41
00:02:58,040 --> 00:03:06,920
drives tend to last anywhere between twice to 10 times as long as TLC ssds

42
00:03:04,280 --> 00:03:11,920
while being quite a bit faster and while you can't cram as much data on an mlc

43
00:03:09,599 --> 00:03:16,360
SSD for the same cost they still represent a good value proposition

44
00:03:14,280 --> 00:03:23,040
whether you just need a small SSD to use as a boot drive or even something larger

45
00:03:18,840 --> 00:03:25,840
for mass storage SLC drives due to only

46
00:03:23,040 --> 00:03:31,439
storing one bit per cell are even faster still and can last for 100,000 right

47
00:03:29,159 --> 00:03:36,280
Cycles the downside though as you can possibly guess is that they are quite

48
00:03:34,000 --> 00:03:42,799
expensive so they're usually only found in Enterprise settings where the fastest

49
00:03:38,760 --> 00:03:45,000
speeds and high reliability are a must

50
00:03:42,799 --> 00:03:49,599
of course there are other important ways that the flash memory in different

51
00:03:46,360 --> 00:03:52,079
drives can vary such as more recently

52
00:03:49,599 --> 00:03:57,840
with the availability of 3D nand which uses memory cells stacked in a 3D

53
00:03:55,239 --> 00:04:02,680
configuration to significantly increase data density you can learn more about

54
00:03:59,519 --> 00:04:04,640
that in this video so while nearly any

55
00:04:02,680 --> 00:04:09,959
SSD will give you better performance than your clunky old mechanical Drive

56
00:04:06,879 --> 00:04:11,640
deciding between TLC and mlc with SLC

57
00:04:09,959 --> 00:04:17,079
not being really relevant unless you're you know contract buying thousands of

58
00:04:14,480 --> 00:04:20,519
drives at once in a data center can be important if you're really going to be

59
00:04:18,799 --> 00:04:24,520
putting your drive through the paces whether you're a video editor running a

60
00:04:22,160 --> 00:04:28,000
new server or you just like to run benchmarks all the time because your

61
00:04:26,080 --> 00:04:34,759
secret aspiration in life is to be just like me speaking of of secret

62
00:04:30,400 --> 00:04:36,520
aspirations what if you wanted more and

63
00:04:34,759 --> 00:04:40,520
