storage

Technically correct?

Yum the corners are my favorite!

No!

Ackshually the corner is centered right on the spindle in the middle of the platters.

Those layers ARE the disks.

Also that's a 3.5" hard drive. They're still current. It's the standard form factor for desktop use. Though most home systems nowadays just use SSDs.

Still though these are used for large, slower storage like backups, media, etc. and used in enterprise.

That's a standard 3.5 inch harddrive. They still exist and are still sold.

Looks like a 5400rpm 1TB WD caviar green. But it's a standard size for desktops. Laptop hard drives are the same size as a SATA SSD. And the m.2 drives are the size of a large gumstick.

But, the WD greens weren't great drives, so nothing of value was lost - I have 6 of them in my house, and about 4 of them are dead or dying.

My dad bought them for a Intel RST RAID array when he built his hackintosh, all the way when the Intel Core i7-860 was new, and snow leopard was the current Mac OS. The array died a tragic, and very preventable death. (He never bothered to replace the first drive that died, and the second drive death completely killed it)

It's a 1TB 3.5" HDD. They still make those today.

Water jet cutting exists yo.

Not saying for sure whether that's how it was actually done or not, just saying.
