What is Hard Disk Drive and Secondary Disk Drive

okay here's what you need to know about hard drives in a nutshell these large drives on the left these are desktop drives these are laptop drives with an adapter. you can use a laptop drive in a desktop to make it fit and in fact new desktops are being built with smaller trays or Bay's. So that you can install one of these smaller hard drives in it, now explain that in just a minute but we're currently still through a transition where some people with older computer shave the older style hard drives and people with newer computers have the newer style hard drives now these this is the old style this is a new style this is the old style.

This is the new style and this is the real new style but what I'm referring to is the interface and when it comes to old and new the ones here are the old one sand all three of these are what we consider.

The new ones with regards to the interface if you look at the back of this hard drive where it would plug in this has what's called an IDE interface and that's where it's got this large ribbon cable that plugs in here and then large power cable plugs in here and on the equivalent laptop drive that's IDE it's got a bunch of these pins right along here and typically it's one large connector that contains both power and data.

Why Hard Disk Drive and Secondary Disk Drive

That plugs into that it's actually pretty easy to bend those pins although they're pretty easy to bend back too much wiggling in the pin will break off and the drive will probably bone good so if you are dealing with shard drive that's IDE that has a large ribbon cable going to it, then it's probably time to buy a new computer don't worry about replacing the hard drive that's my advice that said let's get these out of the way because these this technology was what was used uphill about I want to say five year sago after about after about five year sago everything started switching to the new connector which is called SATA or SATA and it's a much different looking connector.

it's got the power connector goes on here I'm sorry power connector goes on here data connector goes on here sometimes. it can even be one connector it's most often to you've seen it in my build article one for power one for data and these things here you don't touch that's for the factory and what's interesting when they made this new adapter, or this new interface rather no adapter was necessary you'll see.

this is the laptop equivalent this is a laptop drive and it's got the exact same connectors in the exact same spacing you see, if I line these up just like that you'll see that the connectors line up perfectly so that way you don't have to have any adapters when you're putting into a smaller device it also helps when you want to pull a hard drive from the machine and put it into like a USB dock that you're using the same connector Used to have to need one connector.

Usage Of Hard Disk Drive and Secondary Disk Drive

For these drives in a different connector for these drives anytime I wanted to hook it up to USB and then power was different separate situation altogether so what's this drive you ask this drives a solid-state drive, now what's the difference between them well these are mechanical hard drives in fact of course these are mechanical hard drives we're gonna get rid of those we're done with those. Now actually I'm not done let me bring that bring this one back let's put that one over there put that one over there because internally regardless of the interface they're the same internally. these two it's just a smaller version of what's inside so this is what you would find inside of your hard drive, now if you open your hard drive up and you expose it to the elements.

you've pretty much ruined it so I don't advise you to open up a hard drive unless you know for a fact there's no data on it the drive is dead or you don't care about the data on it and you want the experience of taking one of these bad boys apart and seeing it for yourself but keep in mind when you put it back together it's probably not gonna work and, if it does work it's probably not going to work for very long it's very important that the the surfaces here remained free of contaminants contaminants so small you can't see them with your eyes and microscopic contaminants will ruin these drives so it's amazing these work at all quite frankly and because the way.

Where Why Hard Disk Drive and Secondary Disk Drive Is used

They work is this spins right like a record and then this head moves back and forth like a needle and that's the sound you're hearing when you'rehearing your drive making that racket when you're doing something like I don't know a defray or something like that and so this one I can tell this one's bad it sounds horrible a solid-state drive dislike a flash drive now if we take solid-state drive and open it up what's interesting is there's a piece of plastic here and it only exists to make the case bigger the solid-state drive is actually too small.

so they had to make it bigger to fit into to replace laptop drive. so this right here is the case right we can get rid of that thesis the actual solid-state drive you'll see it's got the same SATA or Interface here but notice there's no moving part snow with the new 3d v-band technology on Samsung Evo 850 series they're saying the lifespan of these drives could be up to a thousand years and currently with the previous generation the 840 Samsung drives that that I read the article on and I'll put links to the articles in the video notes below they said.

How Hard Disk Drive and Secondary Disk Drive Works

It should last somewhere around years under heavy usage, or something along those lines or yeah it'll be in the article but regardless this is the drive and again it's just a flash drive, but it's very very fast infarct in general. this type of drive will be three to five times faster than this drive mechanical drive either in these and the capacity of this will be about one third the capacity of one of these drives for the same price actually for quite a bit more right.

Now you can get mechanical drive like oops a mechanistically these started around $50 and the USB drives let's say $50 for 250 gig sand a 250 gig solid-state drive runabout 150 dollars right in that range. so the prices come down but this is the way to go anytime you can because it's much more reliable it's much faster you never never ever fragment solid-state memory this is called a solid-state drive because it's there's no moving parts it's in a solid state you understand this has moving parts so these are mechanical drives normal mechanical HDDs or hard disk drives this is an SSD or solid-state drive and when we put it back and it's in its case here.

which it just kind of I'll just slaps back together you see how it makes it bigger makes it thicker and by doing that if Actually rotate everything in the right direction when we put this back together you'll see that it resembles the same size and shape as our desktop as our laptop drive I got to get all the rightwards out as our laptop drive right.


Here let's say I probably have other factors okay so here's our laptop drive that's mechanical or our HDD here's our SSD and look they're about the same thickness same size same length same width in that way you can replace your drive if you have one of these in your laptop wit hone of these and what this will do is give you much more reliability it's gonna use less battery power and requires less power to run which could increase the battery life on your laptop and it'll read three to five times faster than whatever you have in your laptop.

Now so even if you're not having problem with your laptop hard drive but you want to increase the speed of your laptop if your laptop has a Sat Abased hard drive then you can replace it with a SATA based SSD it's that easy that's how you know if it's compatible the other hand if your laptop has a hard drive like this it's obsolete in time to replace the laptop so that's a little bit on hard drives 101 now one last thing is why do you have a hard drive for the reason you have a hard drive is that when you turn your computer off it forgets everything you know.

if you've ever been working on something and you've lost power while you were working on it you've lost that document or that whatever it was you're working on because it didn't get saved to the hard drive the hard drive holds on to all the data well the system is off when you turn the system on it doesn't know anything it has to be reprogrammed every time.


so that's what we call loading bandit loads the operating system that most of us use Windows some version of Windows, and then within Windows we have our programs and within our programs. we have our data we always talk about backing up data because we can always reinstall programs, but we can't recreate data and data recovery can be very expensive now I'll have some videos on data recovery basic data recovery coming up soon or in the future I don't know how soon it's gonna be but they're coming up and you can replace even on your desktop.

if you have a mechanical Drive like this you can replace it with solid-state drive and if your case there if your computer case doesn't haves spot to install this you can buy an adapter that will make it fit this size also they were making solid-state drives for desktops and other all it is is the same little tiny circuit board right here they just put in a bigger case that's all it is there's your SATA connectors they're all the same that's all it is all it has to do is making the system faster more.
