I guess you're referring to solid state drives - WTF has that got to do with power relays?

garypTVRS3 - Have you checked/replaced the yellow connector? If not that bit of OE really does need checking. Ignore the general rule here, if it an't broke yet it will (at the most inconvenient time) so replace it.

For many years the majority of computer users installed operating systems to a disk and while computing could store any files on the same disc, these disks are part of what's known as a magnetic storage device and named as Hard Disk Drives

Hard Disk Drives (HDD's) are of the electro mechanical type and the main mechanical parts are moving fingers that read the information on the disk and a motor that spins the disk at a very high speed of up to 7200 RPM and sometimes higher but 7200 RPM drives for operating systems are the most common

HDD's are very troublesome due to them being very sensitive to shock and their use of moving parts

Several years ago companies made great progress in designing electronic storage devices that can have an operating system and user files written to them and deleted from them many times over, these devices are known as Solid State Drives (SSD's) and have in the majority of cases proven to be extremely reliable and work at far greater speeds than HDD's do

6 x SSD's can be fitted in the space that a standard 3.5 inch 7200 RPM desktop HDD takes up

In answer to your above question - It is known as evolution - Progress for the better - Get things working faster while at the same time using up less space and being more reliable

A Solid State Relay has no moving parts and is not affected by vibration

A mechanical relay suffers from volt-drops across its contacts due to arcing, its armature does wear over time and it doesn't enjoy being shaken about due to its use of delicate armature windings

You may or may not live long enough to witness mechanical relays being a thing of the past

You haven't educated me, but if you enjoyed writing it then good for you.

I hope you understand that the suitability of electronics for data storage in a computer tells you nothing about the suitability of electronics for power switching in a car.

just stumbled on this thread and fascinating reading - I knew absolutely nothing about SSD's so googled and read this article

https://www.electronics-tutorials.ws/power/solid-s...

very interesting - once costs come down then I agree with Penny - that will be the future

Wow what a read, thank you very much for the link

This surely means that sometime in the near future switches won't have cables, there will be buttons similar to switches that when pressed will allow light to pass through them and that light will travel through a strand of fibre optic that will control a solid state relay

Switch panels with lots of buttons, strands of glass and one wired LED = Heaven for all of us

Thank you once again for the link

Come on guys, play nicely please.
As there's room for both in our 'pistonhead' lives.
My telecoms career started over 45yrs ago (now retired) on loop disconnect/pulse dialling connected to Strowger equipment. All electro mechanical with no brain other than that of the engineers. In the average small UK town that meant at least x2 full time tele exchange mtce engineers continuously doing both preventative & corrective maintenence on it. In the 70's/80's solid state & intelligence came into play. Soon followed by disc drives, can-bus wiring etc etc. And now we all rely on broadband, PC's, cars with can-bus wiring to peripherals (door locks etc, to you and me).
And at home I go into my garage and bang 30yr old relays against the wall, break open the tin can, and nail file the contacts, just to see if I can breathe new life into it !!!
So there you are....
Oh, I've got a £50 digital wrist watch that'll keep perfect time for around 200yrs.
But I prefer my Bremont chronograph that I have to wind up.

And my point is.... None of us are stupid, our hobby is just that, and there's nothing wrong it doing it your way, even when it all goes horribly wrong. After all who ya gonna blame ?
Finally... Ugh, those solid state relays are damn ugly.

I can't see SSR replacements for mechanical relays being adopted in the mainstream. They're an awkward compromise between old tech and new. I think it's more likely that CANBUS or its successor will get so cheap and reliable that everything electrical will just plug into a bus and switch itself locally. No more fan relays and wired motors - instead a £0.01 ASIC that combines a BLDC controller and comms interface. Just getting rid of all those discrete analog wires and plugs and fuses and so on would simplify things immensely.

But obviously not happening on an S3.

in 20 years time when doing 'another' ground up refurb on the S and a full 'rewire and modern motive power' upgrade, the S MAY have CanBus and electric engine.

In summary,

You can knock it, you can be abusive towards others, you can use or abbreviate swear words to show some disgust, you can post a load of nonsense but none of this will hold back electrical technology

A company invests much money into research to create electronic parts for the future that will be proven reliable before being marketed

Mere mortals at PH knock the products, some even commenting that they will be problematic

Surely I must be dreaming, this hasn't really happened........
