look I get it picking a storage drive for your next rig can be a difficult process currently
SSD prices are very respectable they've got many storage options many different
speeds to consider many different prices I really this video is appropriate and I must
confess that this reddit post of all things was what prompted me to create this video
believe it or not some good can come from that cesspool we'll discuss that and more
in this video not read it but the SSDs so here we go another one for the crash course playlist
so there are two basic form factors you should keep in mind when choosing your next SSD the two
and a half inch drive and the in bat to drive much smaller the former looks something like
this it's usually mounted to SSD trays in modern cases though they can be placed really anywhere in
a build upside down sideways duct tape behind the motherboard tray you get the point I've benefited
the stylus freedom of placement it'll work with really any relatively modern motherboard boasting
SATA ports I recommend SATA 2 or 3 and isn't composed of any moving parts meaning they aren't
as fragile as their hard drive counterparts a few pros and cons of a 2 and a half inch SSD for one
because they use the SATA interface you'll deal with higher latency 'z and lower bandwidth overall
and these drawbacks result in significantly slower effective transfer rates because the
SATA interface is the bottleneck typically in the realm of about 500 megabytes per second from both
the reads and writes unless you have a crappy drive and then typically the writes are trash
and the reads are respectable these speeds mind you are still several times faster than hard
drives meaning they'll still be the preferred OS drive expect boot times in the realm of about 10
to 15 seconds depending on what you have loaded on the operating system to slower drives using
the SATA interface are much cheaper than their PCI siblings so these straps should be considered in
more budget oriented builds 500 gig 860 Samsung Evo's for example these are great drives by the
way are only about 75 bucks each I recommend these if you aren't looking to break the bank
I've linked them down below I have first-hand experience with these even the 850 Evo's were
fine but these 475 or so US dollars are a steal and three you'll need to connect to external
cables to these drives one SATA data cable and one state of power cable right next to its the bigger
one overall just a tad more bulk added to your build but again definitely worth it if you're in
the market for something relatively affordable and decent in terms of speed the next SSD form
factor is MDOT - they're 22 millimeters tall and can range and basically length from 40 millimeters
up to maybe 120 140 millimeters I really depends motherboards typically support all the different
lengths and the height again will be almost always 22 millimeters in that - actually stands for the
second generation of mini SATA hence the M in the name the form factor attaches to the computer
either via pcie three and occupying up to four lanes more on that a second or say two three or
usb3 the physical connector for this kind of drive looks like this right here I'll show a
close-up which can be found on again most modern motherboards now a common misconception here is
that since these kinds of drives use a different connector they must inherently operate a much
higher or lower speeds when in reality the speeds of these drives are largely determined by the way
in which data is transferred not necessarily by the form factor the diagram I mentioned earlier
on reddit comes in handy here thanks to user Alex 2003 super for the original post the two
technology is distinguishing em 2 drives apart are SATA and nvme we've already mentioned SATA
whose accompanying drive speeds max out at around 600 megabytes per second which is why you want
likely to find any SATA drive in either the MDOT two or two and a half inch form factor pledging a
speed above this mark the SATA interface would literally become the bottleneck so this drive
for example is a SATA MDOT to drive notice how it doesn't promote transfer speeds above 600
megabytes per second in fact on the box I don't even see it listed and it's probably because it's
nothing really to be excited about if you want to pass this off as a much faster drive just
don't put how fast the drive is on the box it's gonna be closer to 3,000 megabytes per second
you better believe that transfer speeds gonna be on the box so that's a way you could tell
that this was a SATA MDOT - just by looking at the transfer speeds you could also tell by the
physical connection on the MDOT to drive say to MDOT twos are keyed twice there is an exception
to this and we'll discuss that later in the video now a few pros and cons of SATA MDOT - SSDs or as
follows one they're physically smaller I mean come on clearly smaller than their two and a half inch
counterparts and can thus be easily installed into any compatible motherboard to the board
of course has to support the hem dot to interface right but don't be just too disappointed here most
boards will have at least one I mean heck even the cheapest a 324 Tyco and find on Amazon supported
one more on that this video or right here and then three these drives are roughly the same price as
their two and a half inch counterparts though you may actually I'm holding the wrong one this isn't
MDOT to envy me drive this one right here might cost just a tad bit extra over its equivalent
two and a half inch on our part but in general if I to choose between the MBA form factor and
the two-and-a-half inch form factor I would choose this one simply because if I wanted to swap this
out or maybe just remove it altogether I don't have to remove say my graphics card to get to
the end got to drive which is that's particularly where the port is between PCIe slots it's more
annoying to remove this and that's really the only reason why I'd prefer this now another kind of SSD
we'll discuss in this video is the nvme SSD now I can hold this thing this is actually from Team
Group it's very fast but also fairly expensive nvme stands for a non-volatile memory express and
it's characterized by its high bandwidth and thus fast storage solutions when memory is non-volatile
it simply means that it doesn't require power to retain stored information you can power cycle your
computer all day long and unless the drive itself dies in the process you'll be able to recover your
data without loss system RAM DRAM is volatile and on the other hand and and that basically means
that the data is wiped from memory when current is cut so that's why you can't use system Ram to
store any important applications or data long term well go into that in further detail in a
future video but for now what you need to know is that nvme storage drives by nature of their
protocols are often extremely fast with respect to their inherent Layton sees and transfer speeds
the fastest nvme SSDs I could find on the market exceed read and write speeds of thirty
five hundred and twenty five hundred megabytes per second or 3.5 and 2.5 gigabytes per second
respectively that is lightning fast and would result in an incredibly snappy system overall os
boot times are often under five seconds can you imagine that and any game save you these drives
load dozens of times faster than a typical hard drive once you go in via me it's very difficult
to look back and that's not to say that all MV messes these are extremely fast a subcategory of
these drives relates to the number of PCIe lanes each occupies so for instance this drive right
here is a two lane SSD whereas this one is a four lane SSD and the difference is basically and if
I wanted to generalize this transfer speeds take this Samsung 970 Pro it uses four PCIe lanes noted
by the x4 ording this is what you want to look for when you're buying an envy any SSD for PCIe lanes
have bandwidth equivalent to about 32 gigabits per second for basically 4 gigabytes per sec
so theoretically the fastest nvme utilizing this interface would cap out at around 4,000 megabytes
per second using the preferred SSD standard other env meas however like this one right here
are limited to just two lanes so that means that theoretical transfer rates cap out at around 2
gigabits per second instead of 4 moving from two to four lanes basically doubles your bandwidth
and this right here is an example of that by the way physically four lane and Vimy SSDs only have
a single key you can see there's just one little notch there but a lot of the Tulane and VMI SSDs
will have two keys just like their SATA in dot 2 counterparts it's it's kind of confusing I kind of
express my frustration with this on Twitter but some tooling nvme SSDs will have just a
single key and some will have two keys like their SATA in bed 2 counterparts so that's really not
a great way it's not an effective or reliable way of being able to figure out which is which
if it's 2 or 4 lanes you have to just read the product description make sure you know which one
you're buying and obviously you should look at the read and write transfer speeds because those will
reveal how fast these drives are and typically how many lanes they're using now here are a
few pros and cons of envy me about two SSDs one obviously because they're much faster in general
they're more expensive alright so typically around twice the price per gig or more or less
depending it depends on the market really which has historically to turn a lot of PC builders
I've got only two for line MVM SSDs in the studio and neither of them are in my personal rig it's
just in my opinion a better value to opt for the two and a half inch or say 2 m dot 2 drives too
many beefier nvme drives will run very hot and may require heat sinks with active cooling to maintain
adequate transfer speeds for long amounts of time to be fair all SSDs will throttle to an
extent under heavy load but this is something you should consider along with your use case
scenario since you're likely to spend hundreds of dollars on these drives you want extract all
the performance you really can now the last a kind of SSD we'll mention just at least mention in this
video is the PCIe based SSD there isn't really much that sets these apart from their Envy Miam
to counterparts save the interface used in this case it's PCI Express versus the MDOT two-port
transfer speeds are essentially the same in fact you can buy little conversion cards that allow you
to connect impact choose to those boards and then let's connect those boards to the motherboard via
the PCIe slot so they're really the same thing it's just the method by which you connect them
to your system is a little different PCIe based drives aren't really as popular since they're much
larger than m2 drives and literally consume a slot on your motherboard they're also typically more
expensive so just really isn't ideal or functional one benefit may be temperatures where some PCIe
and viennese may have bulkier heat sinks or even fans but again thermal throttling really only
applies to those interested in transferring gigs of data at a time by the way I'm not gonna discuss
a unit two drives in this video they aren't mainstream yet and are pretty expensive assuming
you can even find them in a consumer market I have however linked a reliable article down below that
may interest you regarding the technology and how it works it is very well written I've also
attached affiliate links to several SSDs in various forms that I trust and have personal
experience with for those interested in picking something up they are also in a video description
those kicked back to do go a long way I appreciate it if you guys like this video thumbs up you know
what to do thumbs down for the opposite click that red subscribe button if you are feeling
extra fancy and I'll catch you in the next one this is science studio thanks for learning with us
