hello and welcome back and today i want

to answer the very simple question which

wd black ssd should you buy a number of

you who have been following the world of

ssds or even people are completely new

to this subject that are finding

themselves in a position where they've

got to upgrade their os driver or their

gaming drive up to a pcie gen 4 ssd to

get some of that sweet sweet high

bandwidth there are wondering when they

go to wd's drives which come heavily

recommended on different websites and

sources and editorials online see the

words wd black and then you suddenly

find out there's more than one of them

that's right the wd black series has

existed for quite a long time it was

western digital's kind of gamer or

professional focused label whether you

were someone in content creation post

production esports professionals or more

the wd black series was kind of their

high performance stuff and it has

existed for many years in hard drive and

ssd form now in today's video i'm going

to focus just on these three drives this

is the wd black sn50m x this is the wd

black sn850 on its own and this is the

wd black sn

7700 now why am i focusing on these

three although there are other ssds in

the market well because all the other

ssds that we talked about before that

such as the um sn750 which is the pci

gen 3 generation or the wd black hard

drive they are kind of previous gin or

even the gem before that these are

current these are basically the most

high performance wd black ssds in the

market right now

despite that as you can see though just

a casual glance they look really similar

in terms of the retail packaging between

them and although they look incredibly

similar and dare i say they are priced

really really similar in terms of

architecture performance output and what

you are getting for your money they are

markedly different and if you get it

wrong on day one you may never know that

you effed up so that's what today's

video is about understanding the highs

the lows and which one of these is best

suited to your needs so we're going to

go through a bunch of different things

about them so

first and foremost

price it's the biggest one isn't it most

of us when we are looking at buying an

upgrade particularly us consumers or

home users we're thinking a little bit

about the old cheddar there and we're

wondering which one is the best value

for money well unsurprisingly the sn

7700 marketed largely as the kind of

more cost efficient and value series ssd

is by far the most affordable there now

there's still ways to look at that you

could look at the individual price of

each capacity tier that we'll talk about

later on but just utilizing the largest

available capacity out there for this

drive which is 2tb

we can see that this drive has utilizing

wd's own website a price point of around

134 dollars per terabyte now to put that

into a little bit of perspective this

one in the middle the oldest drive of

the three the sn 850 arrives with a 146

dollar per terabyte level there so again

not a tremendous difference a little

over 10 to 12 dollars per terabyte makes

you think why on earth would i bother

with this with such a small increase per

terabyte well first and foremost bear in

mind as an average based on the largest

capacity if you go for a single terabyte

the prices do differ quite wildly

but two the architecture of these drives

is actually quite different and

sustained utilization and performance

will make a big difference in terms of

efficiency and power consumption

something i'll touch on later on but

when we move to this end of the table

with the newest drive for the free the

sn850

x it should be mentioned that that drive

the price point because it's the newest

and arrives with the largest capacity of

the whole range available in up to 4 tb

the price point and the cha-ching per

terabyte

actually a little bit more harsh

arriving at 174

dollars per terabyte that is a big old

jump from that 134 at the end of the

table there so

what exactly is this drive doing

charging that much more other than the

fact that it's the newest why on earth

and how on earth i should say can it

justify that price point well in a few

small but in ultimately i think

meaningful ways

across the three of these there are

different priorities when it comes to

the capacity so if you are someone that

prioritizes small capacities you're

looking for an os drive or a scratch

disk for your editing

this drive here has probably got your

back arriving at 250 gig 500 gig

1tb and 2tb overall now if you're

someone that champions capacity you want

all the data you can you're going to go

for this the wd black sm 850 x because

as mentioned it knocks around in up to

four terabytes arriving one two and four

terabytes of storage now if you are

someone looking for the middle ground

unsurprisingly you're going to go for

the drive in the middle this arrives at

500 gig 1tb and 2tb thereby leveraging

the price point of course as mentioned

earlier on but also arriving in i would

argue the more popular capacity is

giving you a little bit of what each of

these two drives is promising in terms

of overall capacity and desirability to

an end user be it for gaming or an os

but more above that that price per

terabyte isn't the only contributing

factor to their hardware environment and

how they achieve that price point now

all three of them take advantage of a

sandisk in-house design controller there

the wd black g2 now at the moment at the

time of recording the um nand and

controller architecture of this latest

generation drive has yet to be

completely clarified something we're

doing there in the background and should

have been updated in the um article

below linked over on nas compares with

our full review but right now the thing

these all have in common is they're all

using an in-house controller they're all

using in-house nand on board with the wd

black in the middle there running with

96 layer 3d tlc nand

and the sn7 7700 arriving 112 layer 3d

tlc nand and i believe that the wd black

sn850 is either running the uh 112 the

same 112 layer nand or maybe up to 164

layer nand we'll have to double check

that and again check out the link in the

description or the text bubbles on

screen but the another big difference

between these comes down to efficiency

because one of the reasons that this

drive exists the sn 7700 is because it

is d ramless now what that means is when

you look at an ssd it's not unlike a

computer insofar as

it has a very familiar architecture the

controller is kind of the brain in a

computer that would be the cpu it also

has the nand that's where your data

actually lives that would be kind of the

hard drives of a computer on its own but

alongside that ssds have an area known

as the memory there on board the d ram

and that is basically kind of like the

spare hands the juggling area of the ssd

to work out its tables and basically do

its job to help process that data

now that can increase the price point it

can also

affect how well the drive can work

because the more memory you've got the

more scratch area you can deal with but

it also increases the power consumption

and more now the sn7 7700 is dram-less

it has no memory on board it takes

advantage of something called hmb host

memory buffer it utilizes a small area

of the on-board client computer's own

memory and storage to get the job done

so the drive

is more affordable because it doesn't

have to have the extra element of memory

on board but also utilizes less power it

can run a little hotter and more

sustained operations will over saturate

the drive earlier than the other two

drives but there's still no denying that

the reason that drive is a little bit

more affordable is due to the absence of

that memory on board and for a number of

users that are running it for an os a

number of users that are using it for

general editing that's going to be great

gamers

slightly less so i would recommend if

you're a gamer you certainly look at

this end of the table and if you're a

ps5 gamer certainly look at the middle

of the table but we'll touch on that in

just a moment because

another big difference between these

three drives is performance let's be

realistic if you were looking at an ssd

in the first place again for you whether

it's for your os for your editing your

content creation or your gaming

performance is a big big big

contributing factor for you there and

across this table you'll be unsurprised

to hear that the more you go in that

direction across the table the higher

the performance let's start with the

lowest one the sn 7700 released in

spring 2022 arrives with a maximum if

you utilize the highest performance on

the 2tb model 5150

maximum megabytes per second sequential

read and 4 900 megabytes per second

sequential write now bear in mind this

is the pc agent 4 ssd pci gen 4 x 4 m2s

have a maximum 8 000 megabytes per

second bandwidth that's how wide the

road is that they can saturate and fill

no drive can fully saturate that for a

number of reasons due to the calculation

between megabytes and gigabytes but also

just the sheer backwards and forwards of

that bandwidth but we can get really

really close now the wd black sn850

released in autumn 2020 nearly two years

ago at the time of recording

this ssd has a reported 7 000 megabytes

per second sequential read and 5 300

megabytes per second sequential right so

again a huge increase over the d ramles

sn 7700 in terms of the read operations

but in terms of right not a tremendous

increase there only around 400 megs

which is still good you know that's

faster than an individual hard drives

worth of difference but still the right

performance on this

is a little lower that's why a lot of

users wd themselves and indeed mark

cerny champion this drive for ps5

utilization because the right

performance is what ps5 kind of

prioritizes the so the read performance

is what ps5 prioritizes the right

slightly less so a lot of that to do

with the more closed nature of ps5 and

how data is encrypted unpacked repacked

and compressed during operations inside

the ps5 render a bottleneck where any

high right performance options an ssd

could provide are fruitless because the

system itself will bottleneck it there

in the middle so read operations is

where it's at and therefore that 7000

megs on the sn8e5

here on the wd black in the middle is

great for your ps5 players

but if we move to that end of the table

with the latest ssd this is where we're

getting the best of all worlds and this

is why content creators post-production

esports users and particularly pc gamers

are going to opt for this drive overall

because as a reported 7 300 megabytes

per second which is already an enormous

leap off of this although an arguable

small leap over this but it's the right

operations that sleep up substantially

there with the wd black sn850x arriving

with 6

600 megabytes per second as it's

reported sequential right operation

sequential being large block data that's

in a row not random but we'll touch on

that in just a moment consequently

clearly it's the highest performing

drive across three of them and although

the um

read operation isn't a marketed jump

from this one the right operation is

substantial

and therefore in terms of performance

unsurprisingly this drive is just

absolutely flawing both of these drives

only so much so on this one but

definitely smashing this one straight

out of the park

now continuing on the subject of

performance we can talk about iops

particularly 4k random iops now what

that means is random data that is

scattered all over the disk and a random

4k io measurement is about how many of

the smallest operation can be conducted

now

per second now the iops rating across

all of these is actually pretty similar

on these two it has to be said yes

unsurprisingly the newest drive has the

highest iops but

the margins of improvement aren't

substantial over that of the sn850

unsurprisingly the more affordable one

once again due to its lack of onboard

memory that dramaless design means that

its maximum number of random 4k tiny

operations per second is noticeably

lower but still very very high rated at

its largest capacity at six thousand

five hundred six

six hundred and fifty thousand read

ielts and eight hundred thousand

right iops they're very respectable

numbers and importantly comparable to

the majority of pci gen 4 ssds in the

market right now that have memory on

board so despite its lack of onboard

memory it still challenges at least in

terms of random 4k iops the majority of

ssds in the market right now now when it

comes to the sn850 we see a tremendous

leap with roy reed iops at 1 million

right iops slightly lower at 720

000 but still one million read iops is

substantial in the extreme and certainly

something to be proud of and those

running databases or larger um if you

are an editor that has a huge archive of

small clips and transitions and basic

tables you have to go back and forth

from of information are going to fill

the benefits there but when it comes to

those uh performance in iops again this

drive smashes everything and right now i

think is the highest rated 4k random

ielts drive in the market right now

although it's read write performance is

by no means the highest in the world

right now in iops i think it does win

with 1.2 million reported read 4k random

iops and 1.1 million 4k right random

iops so again substantial numbers there

and this gives you some indication about

why its price point is higher it's not

just about the capacity it's about how

it's managing to manage that much

storage as fast as possible there which

brings us ultimately down with all three

of these drives with exactly the same

durability i might add so if that was a

concern they're all rated at 0.3 drive

rights per day or um 300 600 1200 or 12

uh 2 400 terabytes written so durability

wise near enough identical it comes down

to who are these drives for and that's

going to be the most important bit here

because if you're watching this you want

to know which one you should have bought

if you haven't already worked it out

from everything i've said from the

performance benchmarks to their own

individual strengths and weaknesses let

me make it nice and clear if you are an

esports professional if you take your

gaming seriously if you are a content

creator if you stream regularly and

ultimately you are looking for a no

holds barred drive experience for your

storage that has practically no

bottleneck

this is the drive for you you're paying

extra for that performance how much is

your time worth work it out you'll

realize that this drive is the one for

you if you are just a dedicated gamer

but more importantly a ps5 gamer this is

the one that's going to be for you

particularly if you're someone that's

looking for a deal because the wd sn 850

is regularly on offer in different

retailers as well as in and outside of

prime day black friday christmas sales

and more and i strongly recommend if

you're a console gamer going for this

drive it did very well in the testing

that we've done in the last 12 months or

here on the channel and i cannot

recommend it enough also it has official

certification now from playstation

themselves and of course sony so do

check that out but if you are looking

for straightforward video editing on its

own and you're looking for a drive that

can recall tables recall databases and

not have to worry about gaming and

sustained operations and constant

this value series drive is the one for

you if you're looking for an os drive

this is the drive for you if value for

money is what's important to you this is

the drive for you this is the drive for

people who are not looking to absolutely

burn rubber this is the drive for those

of you that are looking for high in

performance but you're not running a

zeon 12 core process you're not running

high in ddr5 memory and ultimately your

rig will not be able to hit these

benchmarks in those situations this is

the drive for you but that has been

understanding the difference in helping

you decide which one of the new wd black

pcie gen 4 ssds best suits your needs if

you've enjoyed this video chuck like it

really helps me know what i'm doing

right and wrong and if you click like i

know i'm getting things right here on
