it makes sense to skimp a little bit on a purchase to save a few bucks
whopper without cheese a keyboard without RGB or a hotel room without the
love tub and there's a breed of SSDs
that's been hitting the market that uses a similar philosophy I'm talking about
SSDs without DRAM that are sold at a
lower price point than most other models well I mean hold on a second Linus SSDs
without onboard memory that sounds fine
why would an SSD need its own ran well
here's the thing whenever your operating system wants to fetch something from
your SSD like a game you want to play or a business plan that you need to work on
it needs to know where that data is
physically located on the drive in order
to know this your SSD keep saying map of sorts that actively tracks where
everything is I mean most people don't know this but your SSD has to move your
data around quite a bit so that you don't end up with a situation where some
of its flash memory cells wear out faster than the others it's a protective
strategy called wear leveling on most SSDs this data map is kept on a DRAM
chip because D ran is much faster than
the NAND flash that your SSD uses for data storage in fact you can experience
this for yourself if you ever use your main system DRAM as a RAM disk something
you can learn more about here keeping the map on DRAM also results in better
performance because it's faster speed means that the OS won't have to wait as
long for the SSD to locate the desired data however it is obviously possible to
eliminate DRAM entirely and keep this mapping data either on the main flash
memory itself or just copy it over to
your system memory after you turn your computer on and as we alluded to earlier
an SSD without DRAM tends to be cheaper
than the one that has it but she does
not necessarily equate to good value
though if all you're looking for is better than a hard drive performance for
the least possible amount of money could that gas station sushi SST be good
enough well as it turns out moving the
data map off the DRAM cache creates some issues that are hard to ignore because
it takes so long for the SSD to locate data performance on DRAM las' SSDs is
usually noticeably slower than it is on
mainstream SSDs especially for random
reads and writes the small data operations that access different parts
of the drive that incidentally make up the bulk of the average users experience
if they have their OS installed on the SSD and with drives that use the NAND
flash to store the data map this has the added drawback of putting more wear on
the drive than it would otherwise have so it'll be slower and then adding
insult to injury it may actually die sooner you might have noticed that the
warranty for a dear analyst SSD is often shorter than for other drives
so if you're trying to save money on your next essay purchase use caution if
you start looking at DRAM less SSDs find
as many reviews as you can about the particular model you're looking at and
you know what now forget it I'm actually not going to recommend any of them it's
better to find an inexpensive SSD with a
dram cache in most cases you don't end
up saving that much money anyway and so the moral of the story here is sometimes
trying to cheap out just isn't worth it though with that said I've heard that
stocking up on store brand aluminium foil is a pretty good idea
and if you're the kind of person who stocks up on not just aluminum foil but
also computers you might want to try out synergy synergy solves once and for all
the problem of having too many keyboards and mice on your desk it's a software
tool that lets you just share one keyboard or Mouse across multiple
systems be they PC Mack or even
Linux-based you just configure where all the different screens are and the mouse
cursor moves seamlessly between them no
more messing around and it's even got great features like clipboard sharing
dragging and dropping between the computers custom hotkeys and more it's
available in basic and pro versions with the latter including SSL encryption to
secure the data sent between the computers synergy is offering a 50%
