more welcome to my long overdue unboxing
of one of the most important ssds on the market this is the 840 Evo it is not the
fastest SSD it's not the cheapest SSD
but what it is is the complete package it's available in pretty much any Capac
City 12250 5750 and 1 tbte they are all reasonably
aggressively priced and because of some unique features that Samsung's
implemented extremely competitive performance-wise in spite of the very
middling hardware specs so that's a bold claim lineus why would you say that and
the answer will come later on in the video after you sit and listen to me
talk about other stuff so first up hardware specs they have Shrunk the
manufacturing process down to we think 19 nanometer but they're calling it 1X
class nanometers which means that prices have come down versus the last
generation product they are still using TLC Nan flash so that is 3 bit Percell
mlc flash making the data densities
higher than what other guys who are using 2 bit percel mlc even in their
entry-level drives are using but because Samsung has made some changes to their
already excellent MDX controller so it's now the Mex Three core controller they
are able to achieve great performance in spite of the inherently much slower
right speeds that TLC flash has to work with so it's also got SATA 3.1 over SATA
3 on the last generation product and they've added Hardware AES 256
encryption so that's basically there see there's a code on the back of this drive
so that's basically a way to make it so someone's completely locked out of your
drive unless they're willing to completely erase it so you can secure your data even from theft in the event
that someone actually gets your drive and they can't even put it in anywhere else and unlock it so endurance is of
course the big thing people talk about with TLC flash because not only does it
write slower it also doesn't write as many times every SSD will die it
actually has a rated number of rights that will eventually kill it now most
ssds will actually last much longer than that rated right speed and you can see
they've done some extreme testing over on Extreme systems go figure they do extreme testing there I just don't think
it's that important even if it didn't last any longer than the rated number of
right Cycles you look at an excellent comparison by a NCH so that'll be linked
in the video description huge a NCH fanboy over here if you guys didn't already know that they estimate that
even with a very aggressive workload these drives which are the consumer
grade drives are going to be lasting for
years depending on the capacity now the larger the capacity of the drive the
longer it's going to last to the point where you're looking at drives that are probably going to last for decades or
die from some other reason rather than die from being written to too many times
and it should also be noted that ssds are much less likely to be damaged by
shock or any other kind of phys physical
you know demise that hard drives can meet because they don't have any moving
parts now let's get into that bold claim that I made about why this drive which
has TLC flash you know a faster clocked Three core controller 400 MHz versus 300
MHz and you know otherwise isn't that
special is the drive to beat and three things turbo Rite rapid and their new
data migration to software so what turbo Rite is is a way of taking part of the
storage on the drive and it varies according to the Capac capity of your particular drive it goes up as you have
more capacity and takes part of that TLC Flash and runs it in SLC mode so if
you're not familiar with SLC that means only one bit per cell all right so
that's even potentially faster than mlc back when that was the performance and
long endurance one in mlc was the redheaded stepchild whereas now it's
high performance mlc and then TLC as the one that is you know perceived as less
reliable and slower so what that means is that when the drive gets written to
it fills up that that SLC behaving cash
first then distributes that data to the rest of the drive at its Leisure that
means that in real world terms the drive is faster unless you're doing a very
long sustained right to it now reads are still fine on TLC flash so turbo Rite
has pretty much no drawback in a day-to-day usage scenario which is very
very cool you can enable it using Samsung's SSD magician software it's
very fast very low latency but it does rely a again on non-continuous use so
again I'm in a non-tech fanboy guys and you can check out their excellent
article on turbo right which is linked in the video description as well next up
is rapid which stands for fast no actually it stands for Real Time
accelerated processing of IO Data and
what rapid does is it allows you to take a gig of your Dam so that is your system
memory and use that to cach the SSD now this one I'm not quite sure if I feel as
you know uh completely POS POS about as I do about turbo Rite because it caches
not only reads but also wrs which means that if your system does lose power in
the middle of it caching something into memory this is not the same as caching
to SLC flash which is still going to be there when the system reboots and the
power goes down memory is cleared when the power goes out so it can cause data
corruption but if you're running on a laptop or anything else that has a
battery backup such as a desktop with a UPS and your system's very stable I
wouldn't worry about it too too much so what it does is it takes up to a gig of
your system memory and allows it to operate many times faster than even the
fastest SSD can because it is effectively reading and writing out of
RAM it's not the same as a RAM dis implementation because it's all
completely uh it's all completely automated unlike RAM disk software which
often requires a lot of manual intervention the next one up is data
migration 2 so what that allows you to do is say okay well I bought this new
SSD but I could only afford a 250 gig SSD and quite frankly the hard drive
that I bought like four years ago is already 500 gigs and I've got all this
data on it what am I supposed to do if I migrate it over what am I are all my
videos and photos and songs just lost in The Ether the answer is no what data
migration 2 does is it allows you to specify two Targets so you can clone
your OS and all the important programs and stuff over to an SSD and then you
can have a secondary hard drive that all your data goes to so it's actually
painless enough to use that even my mother can do it so we're going to do a
follow-up video on rapid the data migration 2 software as well as turbo
that's going to be hosted by slick but basically without even watching that all
you need to know is this drive just
pretty much rocks thank you for checking out my unboxing and overview of the
Samsung 840 Evo don't forget to like this video if you liked it dislike it if
you disliked it leave a comment if you have something to say to me how much did
Samsung pay you to make this video Believe It or Not sometimes I just like
stuff and I'm allowed to do that and as always guys don't forget to
