a common piece of advice given to new computer tinkerers is that the single
best upgrade you can give especially an older PC is a solid state drive or an
SSD not only because this removes the hard drive bottleneck but also because
in general any SSD is going to give you a significant performance boost even if
you don't agonize for hours over the exact model you're going to buy and just
end up spending 10 seconds picking out the highest rated one on Amazon but many
many of you also have higher performance
requirements than simply faster than a hard drive so today we're following up
on our guide on which SSD to buy which
you can check out here with an explanation of the different kinds of
flash memory that you'll find not only in ssds but also in things like
removable memory cards and USB thumb drives So currently SSD flash memory
comes in a few main flavors s SLC mlc
and TLC which you will sometimes find in
the SSD product description but unfortunately not always which sucks
because these three things could have a huge impact on the performance of your
drive but how well the letter c c yeah
that way in these variety stands for
cell as in the memory cells in your ssds
that store data so depending on the type
each cell can hold a different number of bits that is the zeros and ones that
make up all Digital Data a single level cell or SLC can hold just one bit per
cell while triple level cells or TLC's
can store three bits per cell NLC
actually stands for multi-level cell so technically TLC is a subset but mlc is
commonly used to refer to two bits per cell
so it shouldn't be surprising then that TLC which can store the most bits per
cell offers higher capacities in fact
their higher data density also makes them cheaper per Gigabyte but there's a
caveat here remember that ssds only last
for a certain number of right cycles and
since the electronics in TLC's requires
more rights per sell because they store more they don't last as long as ml C's
and slc's and they also tend to be significantly slower for these reasons
you will mostly find TLC flash on
lower-end ssds and portable storage
devices instead most mainstream and
higher-end consumer ssds these days use
mlc Flash which represents a nice compromise between data density
longevity performance and price these
drives tend to last anywhere between twice to 10 times as long as TLC ssds
while being quite a bit faster and while you can't cram as much data on an mlc
SSD for the same cost they still represent a good value proposition
whether you just need a small SSD to use as a boot drive or even something larger
for mass storage SLC drives due to only
storing one bit per cell are even faster still and can last for 100,000 right
Cycles the downside though as you can possibly guess is that they are quite
expensive so they're usually only found in Enterprise settings where the fastest
speeds and high reliability are a must
of course there are other important ways that the flash memory in different
drives can vary such as more recently
with the availability of 3D nand which uses memory cells stacked in a 3D
configuration to significantly increase data density you can learn more about
that in this video so while nearly any
SSD will give you better performance than your clunky old mechanical Drive
deciding between TLC and mlc with SLC
not being really relevant unless you're you know contract buying thousands of
drives at once in a data center can be important if you're really going to be
putting your drive through the paces whether you're a video editor running a
new server or you just like to run benchmarks all the time because your
secret aspiration in life is to be just like me speaking of of secret
aspirations what if you wanted more and
