everyone Welcome to less than 5.6 hybrid drives and flash storage, artistic drives and storage.
Okay. And this lesson work on the first start talking about hybrid drives. And from there we're gonna transition to talk about flash storage, Specifically compact flash SD cards, mini SD, micro SD and finally S t x t. So let's go ahead and jump right on in.
So hybrid drives were S s HDs. What if you want it the best of both worlds in storage of the stability of a traditional hard drive. But the fast access oven SST So that's where Harvey drives come into play. They're just that
hybrid drives have both the spinning platter and SST memory hybrid drives use the Hartz dr as storage in the S S. D s cash
after the data is saved to the SST, or cash portion is then written to the hard drive for long term storage.
Now, hybrid drives can come in two sizes of a 3.5 inch or 2.5 inch. Now, however hard hybrid drives they're limited on the SS SD storage, so they're a little bit smaller than a regular SSD drive. Um,
so storage space will be a little bit limited for you. So you want to take that as a consideration,
and the hybrid drives are also they will learn what files could be cashed, and we'll move those files automatically for you. So that's another limitation you may wanna consider. You can't manually move the files to. I want this file over in the SSD, and I want this final long term storage.
It'll see what files can be cashed and move those automatically.
So initially, the travel start off slower. But as it begin to learn you, it will be faster. Another important factor of these drives is safe once he found a laptop and you have limited Dr Days, but yet you wanted the SSD and long term storage. The hybrid drive would be perfect for you
hybrid drivers perfect for those situations where you have a laptop or mobile device and it's limited on Dr Days.
You can get the again the boat best of both worlds using the SST portion as well as the traditional hard drive in a harbor drive.
Now we're gonna transition over to flash storage. Now, flash storage covers a wide range of memory on devices used to store digital information on mobile devices.
The basis of all storage cars used in these devices is flash memory. Now these devices we use on a variety of ways every day, whether it's a tablet laptop, mobile device, phone, digital computers, game consoles. There's a lot of different equipment that we use
that have flash memory for storage stored for settings,
storage for different formats that we need to say to within those devices.
So let's start talking about one of the earliest forms of flash storage was, which was the compact flashes again? This was one of the earliest flash storage cards used. They were used in professional and consumer equipment. If you remember the older digital cameras, they have the compact flash cards in A.
I remember in a point of professional side
in networking equipment, voice over I P equipment. Any type of equipment that needed the setting saved that came with the compact flashed. Even network equipment we used for testing data had flash memory storage, and they were in the form of the compact flash cards,
and they were either the metal of the plastic cards and have a 50 pin interface,
and these cards supported the fat 12 that 16 in fat 32.
The form factor sizes for these two particular off cards were the 43 by 36 by 3.3 millimeter in the 43 by 36 by 5.5 millimeter form factor. So again, compact flash one of the earliest flash storage cars out there in the market.
Then we moved to the SD cards or the Secure Digital, which was a proprietary, non volatile memory card for men introduced in 1999. Improvement over multimedia cards. And this was a calibration between major storage vendors at that time, and basically
they paved a way for the new technology is an improvement over the multimedia cards
Secure Digital actually was the name of the company that was formed,
and the SD car was one of the first formats out of that. The coming together of those companies. Now the SD card had a manual right protect switch on the side so you could manually protect your card for in just making read only, or you can sweep, make the switch the lever, and you can record on that
so that was the first of its kind on the market.
The form factor size for that particular car was at 32 by 24 by 2.1 millimeter, and one of the initial sizes that came out was the two *** capacity, but that actually increased from there.
Then we move on to the many. SD asked you still, within a secure digital family, it was the mini SD card. It was originally manufactured for mobile phones and small for small form factor devices. Its size was a 21.6 by 20 by 1.40 millimeter form factor.
Then, as technology moves on and improves, as it always do, things get smaller.
So then we had the micro SD again of this secure digital family was manufactured again for small form factor mobile foreman devices or smaller devices. As things get smaller,
this is actually one of the smallest card's memory cars that you can get. It's a 15 millimetre by 11 millimeter by one a millimeter form factor now important note here, the Mini SD and the micro SD do not support the ma'am. The manual right protects which, but you could put that car in an adapter
that do support that
And finally, we have the S D x Do secure digital extended capacity. This car came from the Secure Digital Group and it supported extended capacities specifications. Car specifications for this card actually supported up to two terabytes
support full HD in performance and speed.
And its form factor was
32 by 24 by 2.1 millimeters on and there you have it.
So we kind of step through and talked about hybrid drives and how that technology is used using the regular traditional spinning platter that you get from a regular to just no hard drive. As Willis says, the technology all in one device.
Then we stepped through time and talked about the flash storage, the evolution from the compact flash to SD, the mini SD, the micro SD and the S D x d. So there you have it flash storage and hybrid drives and that is it for this lesson.
