Slowmotion video of a HDD in action: that’s why SSDs are superior

Posted at 18 June 2012 17:11 CEST by Jan Willem Aldershoff

If you’re a techie, you probably know that a hard disk drive is simplified a spinning platter with a moving head above it to read and write the data. This means that a hard disk has a lot of moving parts and this is also why SSDs are rapidly becoming more popular. The moving parts make a HDD more noisy, slower, ¬†less energy efficient and more susceptible to damages than SSD drives. ¬†Usually you don’t open a harddrive and it’s therefore very likely that you’ve never seen the internals of harddisk moving and operating.

But some guys going by the name ‘Slow mo guys’ have put a movie on Youtube which shows a hard disk in full action, in slow motion. And you’d better see it, so you can explain your kids in 10 years what those HDDs where and how they worked. Just like you probably need explaining on Floppy Disks, remember?

    Not sure what to make of this post, DoMiN8ToR. We all know that performance-wise, SSDs are superior to HDDs. However, when considering cost-per-GB and drive volume size, HDDs are superior. Slow news day? LOL.

      So true regardless when the cost of HDD is still less expensive compared to SSD of which I find it hard to justify getting a SSD at this point in time when I don't need all that fast speed for what a HDD can do and the capacity it has to offer as well as price/capacity SSD still can't compete with. Just take comparison if you bought many TB of HDD would you think the same amount of money on HDD would buy you the same one SSD the answer no way would anyone be that ready to loose their IT jobs for doing something that cost their employeer that much without much in return. So there are other factors being one the Price is the big on limiting SSD from becoming the replacement and since HDD are still being made and manufactured along side SSD I doubt everyone around the world can afford SSD prices. That is what they manufacture of SSD has to consider HDD still being used and replaced even if the warranty is less they would be less inclined to kill their cash cows thinking they can get more from SSD when HDD will suffice for most users even if they game.

      As for slow video maybe they should consider all the junk being loaded that causes those slow loads and playback rather then just blame the HDD for the slow playback. I seen where people had so much junk loading and toolbar and screen junk loads that caused the system slow down and once those junk was removed the system ran like new. So just blaming the HDD being slow is just a no brainer there are many other factors like what users install on their system without thinking or knowing it will be a cause and effect that will slow their system down. They like to have so much stuff running and then ask why is my video so slow and don't take time to think what did I install to slow my system down????

        That's an interesting video though.

        I've never seen the mechanism in a hard drive in action before and the speed of that is amazing!

          Liquid cooling for HDDs is an innovative technology

          Can you imagine what happen to HDD when downloading a torrent? There are a lot of read/write operations

              I agree. Can't seem to find a 2TB SSD for $90...

              Disc platters actually are water proof, they're a glass-metal compound. Not sure about the additional electronics though. The casings make great ashtrays though.

              It's a shame they didn't film the reading parts more closely and from different angles. It's actually a very interesting process.

                Back in the good OLE days of SCSI drives, those things got so damned hot that people used to leave the cover off for cooling purposes (summertime, of course).
                Also, I've seen PC enthusiasts put a clear cover over the internals just to see the parts move through the mounting on clear plexiglass cases.

                Of course I wouldn't mind all that technology to be (in 1-3 years time) replaced by a 4 terabyte USB (3.0) flash drive the size of my thumb. Not as sexy, but you could stack 8-10 of them and have 32-40 terabytes of.. well, whatever.. pron, tron, taiwan, king prawn
