The 16TB drive I have in my desktop PC has 8 double sided disks, and 16 heads to read and write them. That's only possible because of helium gas inside the drive, which lowers power draw, drag and heat output to allow for thinner disks. Amazing how we've come so far.
40 years ago I worked at a joint (International Memories Inc.) that manufactured hard drives about that size holding 20 MB. Now most individual TH-cam videos are considerably larger than that.
It is crazy considering at an event my friend and I shot over 64 GB of footage or the equivalent of 3,200 of those 20MB drives and the SD cards could easily fit onto a postage stamp!
Going WAY back to 1974, I used to work for a company called Control Data. They made main frame computers for companies like Ford and Chrysler. The disk drives in those computers were the size of a dishwasher. I don't know how much data they held. Today, my home office PC has two Solid Drives (no moving parts) with each one rated at 1 Terabyte. My, how things have changed. The only thing constant in this world is change itself.
Why? They messed up how ETERNAL drives were made and only show how internal drives are made. They didn't bother going through the production of adding an internal hard drive to a shell and the circuitry needed to make it work via USB drive. Better off watching "How It's Actually Made"
i worked for IBM in the late 90s and were manufacturing 16Gb hdds. all parts were put in manually. discs were the hardest . also after screws had to vacuum the screws bar the motor screw as it contained magnetic fluid which if leaked the whole line had to be shut down ,everyone out to change the protective clothing ,then wipe everything down with isopropanol. we were basically the robots like in the vid
They forgot to mention that particular plastic is resistant to static charges so that during shipment any static charge doesn't damage the hard-drive permanently
The funny thing… the drives they show being assembled aren’t exclusively external, they are just drives. “External” drives just have a casing and a cable to connect the drive connection to a PC via usb
That's right, I still remember decade ago it's my first time turning an "Internal" HDD into an "External" HDD just by plugging the connector/adapter to the "Internal" HDD. At that time I thought I'm so stupid for buying 2 external HDD beforehand. Lol
@@HelloKittyFanManall of that stuff would be considered "trade secrets" because if they do something slightly different than another manufacturer that makes thier process just the tiniest but cheaper or more efficient then that other company could "easily" start using that same process and gain an edge over the original company.

Controller board? The board on the drive would be the same, there just would be a SATA-to-USB adapter, with a separate board in it. Or, if a large enough batch of hard drives is made to be specifically used in external cases, the drives might get custom boards that have USB port directly built in place of SATA port in regular drives. That saves the cost of separate adapters, and allows making the external drive a bit smaller (by the size of the adapter).
I guarantee you the cap and spacer used on the platter is NOT stainless steel. They are aluminum coated/plated with some chrome/stainless steel like stuff. At first I thought it might be titanium because it was light and not magnetic, but hit it with a bench grinder and the lack of spark tells you it's aluminum. Steel, including stainless steel has an orange spark, higher carbon steels have more spark. Titanium has bright white spark when you grind it. Aluminum has no spark when you grind it and you should not grind aluminum on a bench grinder at all unless the grinding disc is sandpaper rather than grinding disc. The reason is that grinding disc is designed to grind steel or titanium, and the aluminum will clog the disc rendering it useless, and worse it may cause the disc to explode.

Impractical. Hdds are very sensitive and any damage can be disastrous and difficult to repair. The data on the drive is often more important than the drive itself, so recovering that in the event of a failure is often your priority.
Near impossible unless you have a clean room with all of the specifically designed tools and software in order to actually repair it..and if they made them out of off the shelf components then the drives wouldn't last 2 weeks at the most.
the best part about this is that they didn't even show how an external drive is made (granted, the only missing steps are to put it into a case and connect a usb controller)
This is how a hard drive is assembled not made. There are many more steps such as how the disk platters in a hard drive are made. That is another process.
They get taken apart, and each part is then tested individually, and if it can be repaired then it is and then it's sent through the normal testing process again
Sure...have access to roughly 2 billion + US dollars or more, have the necessary land/buildings in order to house all of the equipment, and then have even MORE money in order to pay engineers to come and set up the equipment, and then hire people who know how to do everything etc. Etc. Look, i don't mean to be an ass, but making hard drives of ANY kind isn't something someone just "starts" doing, it takes literall decades of investment and learning in order to even begin the process, much less have any chance of actually making your company work in an industry that is absolutely DOMINATED by roughly 3 major corporations, that being Western Digital, Seagate, and samsung(the three most well known manufacturers in the world). In all likelyhood they would do a LOT to snuff you and your "startup" out like a burning cigarette.
@spec_opsgaming : Thanking you for advice and possible adversity in setting up such industry unit. Besides 3 major competitors there are lot of other manufacturers also doing well in the market. My country has a big regional market opportunity of at least 1.5 billion of customers, If only a 1/10th of market shares of others could be grabbed then it wouldn't be difficult to get return of investment safely in a decade. We would seek our government to impose ban or tighten import SSD, HDD from overseas so that it could help easy access to the regional market with no player.
A computer hard drive (or a hard disk or HDD) is one kind of technology that stores the operating system, applications, and data files such a documents, pictures and music that your computer uses. The rest of the components in your computer work together to show you the applications and files stored on your hard drive.
My local MicroCenter has 15 external drives over 12 TB and 23 over 6TB. You are incorrect. WD has an 18Tb. Seagate has a 20Tb. Solid State Drives (SSDs) are the one's that don't go over 4Tb yet.

Can confirm. Those bits are definitely aluminum.
And now we have SSDs, how time flies by.
Hopefully someday we can figure out SSDs that can handle media storage and heavy read/writes without unaliving themselves.
