>> Hi everyone. Welcome to lesson 5.6,
00:00
Hybrid Drives and Flash Storage,
00:00
alternate drives and storage.
00:00
In this lesson, we're going to first start talking about
00:00
hybrid drives and from there we're going to
00:00
transition to talk about flash storage,
00:00
specifically compact flash, SD cards,
00:00
mini SD, micro SD, and finally SDXD.
00:00
Let's go ahead and jump right on in.
00:00
Hybrid drives or SSHDs.
00:00
What if you wanted the best of both worlds in storage?
00:00
The stability of a traditional hard drive,
00:00
but the fast access of an SSD.
00:00
That's where hybrid drives come
00:00
into play. They're just that.
00:00
Hybrid drives have both a spinning platter
00:00
and SSD memory.
00:00
Hybrid drives use the hard drive as
00:00
storage and the SSD as cache.
00:00
After the data is saved to the SSD or
00:00
cache portion is then written
00:00
to the hard drive for long-term storage.
00:00
Now, hybrid drives can come into sizes
00:00
of 3.5 inch or 2.5 inch.
00:00
Now however, hybrid drives,
00:00
they're limited on the SSD storage,
00:00
so they're a little bit smaller than a regular SSD drive.
00:00
Storage space will be a little bit limited for
00:00
you so you want to take that as a consideration.
00:00
Now, hybrid drives are also,
00:00
they will learn what files can be
00:00
cached and we'll move those files automatically for you.
00:00
That's another limitation you may want to consider.
00:00
You can't manually move the files to,
00:00
I want this file over in
00:00
the SSD and I want this file on long-term storage.
00:00
It will see what files can be
00:00
cached and move those automatically.
00:00
Initially the tribal start off slower,
00:00
but as they begin to learn you,
00:00
it will be faster.
00:00
Another important factor of these drives is
00:00
safe or unsafe out a laptop and
00:00
you have limited drive bays.
00:00
But yet you wanted the SSD and long-term storage,
00:00
the hybrid drive would be perfect for you.
00:00
Hybrid drive is perfect
00:00
for those situations where you have
00:00
a laptop or mobile device and it's limited on drive bays.
00:00
You can get though again, the best of
00:00
both worlds using the SSD portion
00:00
as well as the traditional hard drive in a harbor drive.
00:00
Now we're going to transition over to flash storage.
00:00
Now, flash storage covers a wide range of memory
00:00
on devices used to store
00:00
digital information on mobile devices.
00:00
The basis of all storage cards
00:00
used in these devices is flash memory.
00:00
Now, these devices we use
00:00
on a variety of ways, every day.
00:00
Whether it's a tablet, a laptop,
00:00
mobile device, a phone, digital computers,
00:00
game consoles, there's
00:00
a lot of different equipment that we
00:00
use that have flash memory for storage.
00:00
Storage for settings, storage
00:00
for different formats that
00:00
we need to save to within those devices.
00:00
Let's start talking about one of the earliest forms of
00:00
flash storage which was the compact flashes.
00:00
Again, this was one of
00:00
the earliest flash storage cards used.
00:00
They were used in professional and consumer equipment.
00:00
If you remember, the older digital cameras,
00:00
they have the compact flash cards in them.
00:00
I remember, on
00:00
the professional side in networking equipment,
00:00
voice-over IP equipment, any type of
00:00
equipment that needed the settings saved,
00:00
they came with a compact flash.
00:00
Even network equipment we use for
00:00
testing data had flash memory storage.
00:00
They were in the form of a compact flash cards
00:00
and they were either the metal
00:00
or the plastic cards and have
00:00
a 50 pen interface and these cards supported
00:00
the FAT12, FAT16 and FAT32.
00:00
The form factor sizes for
00:00
these two particular cards were the 43 by 36
00:00
by 3.3 millimeter and a 43 by
00:00
36 by 5.5 millimeter form factor.
00:00
So again, compact flash,
00:00
one of the earliest flash storage
00:00
cards out there in the market.
00:00
Then we move to the SD cards or the secure digital,
00:00
which was a proprietary non-volatile memory card format
00:00
introduced in 1999.
00:00
Improvement over multimedia cards.
00:00
This was a calibration
00:00
between major storage vendors at that time.
00:00
Basically they paved the way for
00:00
the new technology as
00:00
an improvement over the multimedia cards.
00:00
Secure Digital actually was the name of
00:00
the company that was formed and
00:00
the SD card was one of the first formats out of
00:00
that coming together of those companies.
00:00
Now, the SD card had a manual
00:00
right protects switch on the side so you can
00:00
manually protect your card and just make it a read-only
00:00
or you can make the switch to
00:00
lever and you can record on that.
00:00
So that was the first of its kind on the market.
00:00
The form factor size for that particular car was at
00:00
32 by 24 by 2.1 millimeter.
00:00
One of the initial size of that came
00:00
out with a two gig capacity,
00:00
but that actually increase from there.
00:00
Then we move on to the mini SD.
00:00
Still within a secure digital family,
00:00
was the mini SD card.
00:00
It was originally manufacturer for mobile phones and
00:00
small form factor devices.
00:00
It's size was a 21.6 by 20 by
00:00
1.40 millimeter form factor.
00:00
Then, as technology moves on and
00:00
improves as it always do, things get smaller.
00:00
Then we have the microSD,
00:00
again of this secure digital family
00:00
was manufactured again for
00:00
small form factor or mobile phone devices
00:00
or smaller devices as things get smaller.
00:00
This is actually one of
00:00
the smallest memory cards that you can get.
00:00
It's a 15 millimeter by
00:00
11 millimeter by one millimeter form factor.
00:00
Now, important note here,
00:00
the mini SD and the MicroSD do not
00:00
support the manual right protects switch,
00:00
but you can put that card in
00:00
an adapter that do support that.
00:00
Finally, we have the SDXD,
00:00
Secure digital extended capacity.
00:00
This card came from the Secure Digital Group and
00:00
it supported extended capacities.
00:00
Specification for this card actually,
00:00
supported up to two terabytes.
00:00
It support full HD and performance and speed and
00:00
its form factor was 32 by 24 by 2.1 millimeters.
00:00
[NOISE] There you have it.
00:00
We've stepped through and talked about
00:00
hybrid drives and how that technology is used using
00:00
the regular traditional spinning
00:00
platter that you get from
00:00
a regular traditional hard drive as
00:00
well as SSD technology,
00:00
all in one device.
00:00
Then we step through time
00:00
and talked about the flash storage.
00:00
The evolution from the compact flash to SD,
00:00
the mini SD, the micro SD, and the SDXD.
00:00
There you have it, flash storage and hybrid drives
00:00
and that is it for this lesson,
00:00
we will see you in the next lesson.
