How a Hard Drive works in Slow Motion - The Slow Mo Guys

by The Slow Mo Guys • 6,900,795 views

Here is a previously unreleased video which was shot almost 2 years ago for our original trailer. Inside a hard drive. Plus a bit of unnecessary destruction. Shot at 1000fps

I'd love to see a solid state drive in slow motion.  That would be some exciting footage. lolz

+00vaag​​​​ Because an SSHD, which uses that of which would be a small flash-based SSD as a cache for a HDD, or a logical drive, by combing a separate SSD with a HDD to achieve the exact same hybrid of two drives, is not a RAM-based SSD that holds all of the data, uses a battery and creates an entire backup to a hidden HDD, for the purpose of making it non-volatile, which is sometimes backed-up separately, to a form of non-volatile storage. 'SSHD' refers to the HDDs that are used by the computer and, also, have a small SSD that holds a certain amount of data that can be accessed more quickly, while the HDD is used for the rest, basically a cache for the HDD. I know for a fact that what I described is to be referred to as an SSD.

+Controversy Owl If what you described actually exists could you then tell me what it is called? Just calling it an SSD is not helpful since you claim there is a subcategory in this matter that is being overlooked. What is this drive called? It sounds like you are confused on the topic of specialized SSD raids. Also, when it comes to the memory hierarchy size need not scale consistently in each level (although it helps). For example, it is possible to have a 2TB cache for a 500GB drive, although that would be odd - but it doesn't make the drive any less of a memory storage compared to the cache. I assume this is not what you're having trouble with, however.

Does a hybrid drive know to store the OS on the SSD part? Or do you have to do it manually?
Report spam or abuse
+Michael Scheu A regular hybrid hard drive usually has less than 10gb of ssd storage, so there is no way to put the whole OS on it. The drive just puts the most accessed files on the ssd part.

+Nitay A. I'm not a fanboy of anything in particular, I use all OSes and the only thing Mac is good for is music, visual art and business, which is sorta my career. "Pro Apple" is like saying Pro Golden Toilet Paper. It's needlessly expensive and there are other platforms that do what it does just as well for a better price. I use a Mac almost every day, I use Linux at home. Mac has good video editing, photo editing, and general music softwares, but that's it. If anything, I'm pro-linux but that's just my preference. If you really have to defend a company that makes "High build quality" devices, then Apple shouldn't be it. I shouldn't need to remind you of the iPhones and iPads. Macbooks are fine, if a bit overpriced, but you're, for all of their products, buying a name. Air Jordans are manufactured the same way as any other basketball shoe, they have a few shiny things you're paying extra for, but most of that price is the name. I own an Alienware, I overpay for my PCs as well, I just can't justify the price of a mac for an average consumer. Unless you work in video or music, you're better off with Windows OS. Each has strengths and weaknesses, Mac's is the fact that it's good at one thing and one thing only and that you're paying an arm and a leg for somewhat mediocre hardware. Windows has versatility but doesn't excel in one field or another and Linux is favored by coders and for use of servers. I've explained this more than once, but for me, personally, Mac simply isn't worth the investment and when people say that it can compete with something that is designed to be as versatile as Windows, I'll call em out. Mac can compete with Linux, they both specialize in a singular task and do it better than Windows, but Windows does EVERYTHING ELSE better than those two. Oh, for the record, I don't care for Windows, this is just "Fact". But remember when I said "I'm not talking OSes"? It's cause I use all of them. I know what each are good at and what each are bad at. I say "Fanboy" because that's the impression you're giving me for claiming Mac is at all even comparable to Windows as an OS. It's not. It's apples and oranges. Might as well be comparing Android to Windows. They're meant for two different things.

Techncially it didn't move "back and forth" 22 times what happened was it Moved 22 Times it moved "back and forth" 11 Times, because 22 / 2 =11 that aside This is still highly impressive, i have pulled a lot of these apart by the way THE PLATTERS ARE WATER PROOF,   I pull them out and use them as coffee cup coasters it saves me from getting ring marks in wooden coffee table but it never seems to stop amazing me that the magnetic can be controlled so finely to produce this result

To whoever says hard drives are in h2o proof is wrong. The water increases friction, casing the drives to slow down, rendering them unreadable to the heads.
Report spam or abuse
+Alexander Necheff I don't know where you get it from that opening it up outside of a clean room is fine, but I really wouldn't suggest doing it. Esp on newer drives. Yes, the torque screws can cause issues aswell, but dust on a platter will wreck the data on it.
Report spam or abuse
+Vaes Joren  As I said previously: "it isn't the best thing in the world for the platters". I have already acknowledged the fact that the drive is not meant to be without a top cover. However it is not as though the second you open the housing all your files are automatically gone either. I have plenty of experience pulling data off of ailing media (hard disk, flash, optical disk, tape) for other people (I learned a very long time ago that it is easier and cheaper to just have a good backup routine in place). I don't recommend running the drive with the top cover off, and I don't recommend continuing to use the drive in production after the procedure either. But you won't hurt anything by cracking one open to get it running long enough to clone the drive at all. Interestingly enough I have only had a couple drives I was not able to recover 100% of the data off of - none of these were ones I opened beforehand.

Every electronic devices should be waterproof if there's no electric current running when it's wet.
Report spam or abuse
So, a factoid for anyone one's that's into that kind of thing. Electronics are water proof. It's the minerals and other impurities in the water that allow it to conduct current. H2O won't.
Report spam or abuse
+50flamingbottles Yeah, totally forgot about this factoid! Also, There are some custom PC builds that are literally submerged in Mineral Oil to keep them cool, which is not the same thing, but goes to illustrate the concept. [most people: any liquid + electronics = busted]

lol at "That last bit was a lie" Basically those arms move tiny particles around on the spinning discs magnetically and arrange them in a way that when read represents the data on your computer. Hence why you should keep magnets away from HDDs.  Water ruining that process is just a given. hehe.

And to those who have been claiming "it was SATA/IDE". It doesn't matter. The only cable plugged into the drive was a power cable for an external chassis. There was no data cable plugged into the drive chassis. BUT, so many people have watched the video to the point where water was poured on the exposed platters.... But they've commented their ignorance before the video said "Might have been a lie, that last one" It doesn't matter if the drive was E-IDE or SATA. It's toast, end of story (except in supremely extreme cases). P.S. It's disheartening to see people commenting their bullshit on a video, especially before they've watched the full film.
