We will probably see the retirement of the hard drive but it will never die. It has a use on backup servers.

[@JaredOwen]

That's true! Thanks LeztGG

[@xdJordxn]

Plus, it's cheaper xd

[@camper1749]

@@xdJordxn Well he's implying that in the future SSDs and HDDs will have the same prices but the HDD will still not be obsolete.

[@xdJordxn]

@@camper1749 I know. Of course, it wouldn't.

[@lintonfr]

@@xdJordxn I would prefer to pay more for faster and better storage. Plus I can fit more SSDs into a PC because of how small they are

now explain how an SSD works!

[@Randomusername1b]

It is something like a ram but it dosnt turn off when u turn off pc

[@junienet]

they wouldn't

[@victorsvidss]

Its a pretty solid explanation hahehahehaheh

[@the486kgman2]

Memory goes into a memory chip. And a small voltage is sent to the chip even if the computer is off or unplugged, it uses the same battery that keeps the time right so to preserve the data and form a sheild to stop hackers

[@xdJordxn]

It's like a usb/sd card, but with more storage and it's more thick. (It's also more expensive)

[@ruelagnes4277]

this is the best explanation of a hard disk ive ever scene explaining how the hard disk actuator arm read and write into the tracks sector, thank you very much

[@scythal]

The hard drive's sector and track format is actually inspired from floppy disks.

[@declansgamereview6523]

I just replaced by HD to SSD and wow, just wow. They are worlds apart in terms of performance. I was about to get rid of my old laptop away and it now works better than brand new.

[@amvymavy]

Yes of course, it is way faster. There's also NVMe SSD which is even faster

[@Aven-Sharma1991]

Love your work man. This was no exception. Keep it up. 👍🏽

[@JaredOwen]

Thank you!

[@BrianThomas]

I know this video is a bit old, but you didn't mention the magnets or power delivery. Nice video. I my son will love it. We've taken a few a part already and powered up a few to see them spin.

[@geekdiggy]

i only JUST started learning about these things in recent weeks shopping for a new laptop. the laptop i'm using right now is a toshiba satellite made in 2009. i've been having to learn a lot about the new stuff.

[@missingno2401]

"so no dust gets inside" *discs are very dirty*

[@JupiterKnight]

not a hard drive, no

[@SpareSimian]

You can safely disassemble one if you have a proper clean room. But clean rooms are expensive. This is what is sometimes needed by data recovery companies that get your data back when the drive is damaged.

[@twasinjunaed6709]

He said “no dust can get inside”,but there is literally lots of dust in the platers!

[@spb1179]

I like how 5 years later and ssd’s are definitely the dominant drive

[@somedubmetakeshi7960]

Arguable, both have the ups and downs

[@Krisztian08]

Jesus you have a warped sense of time.

[@BigOlSmellyFlashlight]

yeah but for mass storage hard drives are still used very often due to the currently 2x bytes per dollar compared to ssds

[@efai]

I would love to see more, this is like a trailer or something, the full video on this topic would be much appreciated..

[@gabracal]

1. Platters rotate in the wrong direction. 2. Read/write heads move from the parked position on to the platters with no headguide.

[@elagelilio1878]

OHHHHHHHHHHHHHHHH!

[@bentheman69]

Whats a headguide?

[@gabracal]

@@bentheman69 The plastic thing that modern hard drives park their heads on when not in use. I learned that the technical term for these is "off-platter parking ramp".

That Leaves Me With TWO BURNING QUESTIONS 1. What Makes The Hardrive Break When You Open It? 2. How Does A SSD Work?

[@Drag0nmaster]

First one, I believe dust gets into it, (as he said) and it makes the magnet connection on a hdd arm thing not able to read as well, but I'm probably wrong so take this with a handfull of salt

[@GamesAndWeirdStuff]

@@Drag0nmaster Thank You For Trying To Explain At Least... Lol I made this comment 7 months ago but no one responded until you!

[@mariotime2507]

@@Drag0nmasterhalfway right ill explain so the reason hdds may break is bc the arms are 15 nanometes away from the platters and dust can be a few thousand nanometers large and will cause major damage if the disk spins

[@Tulien1]

Don’t stop making videos ever

[@Scripture-Man]

So you've got a fast-spinning disk, being read by an arm moving faster than the eye can see, at a microscopic distance? Makes me realize how fragile these things are. Now I feel scared about mine breaking!

[@johnuferbach9166]

as long as you don't drop it / open it ect. it should hold up pretty well :)

It's amazing how a platter can store information

[@Dargonhuman]

Platters: They're not just for food anymore!

[@OopsieGoopsie]

It's just like a cd

[@Dargonhuman]

@@OopsieGoopsie Not exactly; CDs store information by having the data physically burned into the material, which is why most disc-based media is one-time use. Magnetic discs store information by altering the magnetic field of the disc, which makes them rewriteable as the field can be altered again and again.

[@kh23797]

Drives fail. As an IT tech, I see a _lot_ of data loss, and often hear, "I _meant_ to back up, but didn't get around to it..." Well, luck is unreliable, so back up important stuff regularly, keeping copies online and/or at remote sites. Google Drive, MS OneDrive, and Carbonite are just three of many (often free) 'cloud storage' options.

[@glenn_r_frank_author]

It is seven years after this video was made... and I think mechanical hard drives have been obsolete for many years already.

[@aresivrc1800]

Disagree. While SSD without a doubt is the future and keeps gaining market share there are still a lot of use cases for HDDs: - Still cheaper per Gigabyte than SSDs - higher capacity than SSDs - Unlike the Flash Memory in SSDs, HDDs can be overwritten an unlimited amount of times without issues. - HDDs do not loose data even when removed from power for years - Still the primary choice for data center drives - Ideal for large data which low performance requirements like video files

[@ORGANIZEDCoNfUsioN]
