Re: The Future of Hard Discs?

Looks good as the form factor is the same (or can be) as conventional disks but ultimately the moving parts and the sequential read/write nature will be a limiting factor.

Re: The Future of Hard Discs?

For now it seems that the price of solid state storage is being kept artificially high, but surely at some point SSD's will replace HDD's in the majority of applications?

The steady increase in speed, arial density, storage capacity and reliability of HDDs' keeps raising the bar for SSD's, but I do get the feeling that the days of spinning disks are numbered.

Text documents and databases require less storage space now than ever, but images and especially video continue to eat disk space. But there must come a time when our demand for storage space reaches some kind of plateau, if not a platter?

Re: The Future of Hard Discs?

I'm a hardware electronics designer by trade. I sat down a while back and read a description of how a modern hard drive works, written by an engineer that designs them.

Even more than I already suspected, these things are a tour de force of physics, mechanical and electronic engineering where every design aspect is stretched to the limit in pursuit of storage capacity and speed. How they make them for £50 is a mystery to me.

Every day, when I switch on my computer and it boots successfully to the operating system some small voice inside me says "well, that's amazing"

I suspect few private users (and far too few professionals) have any kind of properly thought out storage or backup strategy.

People tend to buy big new external hard drives as their old devices run out of space and become obsolete. Rather than using the old drives as part of a reasoned strategy they simply duplicate again, and again, and again (and probably have copies on multiple cloud accounts too)! But ask them to locate any one image and they will probably struggle.

I use a file server to run my small business which has 120 GB PCIE SSD storage space allocated to current projects and clients, plus all of my data sheets, accounts and other information. So far, after 25 years I have used 48 GB of this space!

I then have 2 TB of file storage on the server (two mirrored 2 TB hard drives) for redundant files and the past five years worth of my camera raw files. The processed Jpeg images only get copied to the SSD drive above when I am happy with them. That way I don't clutter expensive SSD space with unwanted images.

My accounts programme and other shared apps have their own 50 GB partition on the SSD, and all of the data is kept well away from the System drive (C:\).

Older files are archived onto tapes in case they are ever needed, but this has only happened twice from memory.

Somebody once said that the heads on a hard drive are akin to a Jumbo Jet flying at an altitude of a few inches above ground and counting every blade of grass. And that was when a big hard drive was about a Gigabyte!

There's so much of our modern life that's equally mind-bending. DSP (digital signal processing) is another wonder of maths, micro-electronics and mass production that underlies the entire fabric of our connected world. Without it there'd be no digital cameras or mobile phones, no digital music or video, no internet, no satellite TV, no GPS, no.... - you get the picture.

Re: The Future of Hard Discs?

Photography is light so I'm predicting the EM1 Mk n+1 will employ quantum computing using qubits. It makes sense doesn't it
Hard drives - maybe DNA or coiled fibre optics in the luxury hand grip sold as an accessory.

I foresee one minor problem, the technology may be dependent on very low temperatures, so thermal gloves may be required.

I can't wait...

Re: The Future of Hard Discs?

I'm waiting for some new imaging technology that makes curved glass lenses obsolete at a stroke (like digital imagers have replaced film, mostly).

I'm imagining some sort of nano-technology zone plate ray modifier gizmo that delivers distortion and aberration free "lenses". This technology will also produce LCD screens that can be diopter corrected - like eyepieces are.

I claim prior art on both of these (c) 2018 and will expect payment in due course.

Re: The Future of Hard Discs?

The way to go I reckon is to have digital sensors implanted in the eyeball, one each side, providing stereo pictures. No need for a hyper USB serial data link, Mk 10, since Mk 15 Bluetooth will be out. The sensors will have PV cells and a tiny super capacitor for night time operation.
Simple really! I'm off to talk with my patent attorney.

Re: The Future of Hard Discs?

Back on topic, the way to stay one step ahead of hard drive obsolescence is to get a print out of your image files using 1's and 0s. Years in the future when you finally want to print the image just renter the 1s and 0's by hand, or use image recognition technology to map the bit pattern. Simple really!

If it is anything like entering the barcode number at the self-scan in our local Co-op you can forget it!

In relation to my recent innovation - I predict some work will be required to stop the “unexpected 1 (or 0) at the check-in”.

You mean carbon nanotube fresnel lenses (go on... google it).

Now that would be neat.

I was told they were akin to a Concorde flying at Mach 2 the thickness of a cigarette paper above the runway, and that was when a big hard drive was 10MB!! And by big I mean 56kg big . It took two of us to lift them.

Check this one out .
