Hey, boys and girls, in this video, we are going to cover SATA and SAS SATA and sets is the drives.
That's the communication, the protocol that is used inside of your computer, between your motherboard
and other devices and your storage.
And a lot of time people find it confusing to understand what really SATA is, what is SAS and what
is the difference between both of them?
So let's spend a few minutes to understand and clarify our confusion.
Very first thing we should know the acronym for these A2 drives.
SATA stands for severely advanced technology attachment and SAS stands for serial attached scuzzy.
Scuzzy stands for small computer system interface, typically pronounced as scuzzy.
All right.
Both say SAS and SATA utilize serial communication.
Serial communication is a way to communicate between your motherboard and your storage device.
Serial communication means that the high res has both lanes.
All right, so far, the both are the same.
Then what's really a difference?
Let's go back in the days to understand what was there before a serial communication.
Both of them used a different communication earlier, and there was parallel communication.
So here is our motherboard in our computer, for example, and here is our storage disk in our computer.
We want to go from the motherboard to the storage or vice versa.
Now, in parallel communication and all the communication days, there were two cable, completely separate
cables.
Consider it as two different highways.
One cable was carrying incoming communication and one a separate cable going out output communication.
So the problem was that is it?
It was a lot of long cables, a lot of cables inside the computer, and that was too much to create
a smaller computer, especially nowadays in laptops.
You cannot have so many cables stuck inside to make it compact.
So then came the serial communication.
Same thing that motherboard was suspended communication or retrieved data up from disk and vice versa.
So in serial communication, there was only one cable, but then that one cable, there were two separate
highways, one for inbound and one for outbound.
So that's when things changed.
Everything started doing compact cable.
It was a lot better.
They didn't have to deal with the two different cables.
So things become a lot easier.
So these were the two difference between power and communication.
All right, good.
Now let's get back to our SAS and SATA.
All right.
The main difference between them is that SAS drives are faster and more reliable than SATA drives.
OK.
This is one big difference.
But once again, let's step back.
SATA and SAS both are that different drive types, and they are known to be different because of the
different protocol or communication they use to communicate with your motherboard.
But you probably think Enron didn't.
We just noticed that both use a serial.
Yes, they do, but there is still a little more difference which you're going to cover next.
SAS is generally more expensive, and it's better suited for use in servers or in processing heavy computer
workstations.
SATA is less expensive, and it's better suited for desktop file storage.
All right.
Now here you will know the difference in SATA cable.
All four wives are placed within the same cable in SAS cable.
The four wires are separated into two different cables.
Hmm.
Aren't you thinking if that's the case in two different cables?
Isn't that the same Cyrillic communication DS?
Why divide the wires into two between two different cables?
OK, so you can connect more devices to one another?
It's not exactly the serial cable technology.
The reason they have so you can connect more devices to one another inside of your computer with SATA
cable.
You can only link the motherboard and a storage device.
You could hook up an expansion device, but that takes up valuable room inside of your computer.
So that's why you are limit, you have limitation with the way the SAS cable, you can hook up the motherboard
to both a storage drive and another piece of hardware that has SAS connectors.
As you see, that's why those two highways are separate, but they are in a compact in the same one
cable.
So here what the highway looks like metaphorically.
OK.
SATA cable.
Los Angeles to San Francisco, think of that way and cable, says Cable Los Angeles to San Francisco
or Los Angeles to another city, let's say Las Vegas.
So you have access to different highways or different cities with SAS because it allows you to have
multiple access.
By the way, I do want it to give credit to this analogy that's given here because I got some of that
information from HP, Seacom, HP Hewlett-Packard website.
They have explained it in a great extent.
So if you wanted to learn more about it, I would say go to their website and learn more about the difference
between smart and says, by the way, that's what I wanted to cover.
I hope it has clear up the confusion.
If you are picking up the SATA, if you're picking up the SAS and the what are the things you're going
to do?
You are able to pick that out and differentiate right away.
Now, if you have more questions, let me know.
