I need quantum now dammit

[deustroop]

I backup alot. I keep two clones of the C:\, "D" and "E". Redundant safety , not the most physically secure I know , but entirely adequate for a personal machine not in the line of fire anywhere near here.So either I reclone the two backups every month or I save, install and delete everything three times. Repetitive Tasks drain the old furnace.

So I want a quantum computer. I want changes to C to also change the other two drives simultaneously. Port the quanta from here to there and save me time to think about more important things. (Like where that gunfire is coming from .) How long before such a thing is here ?

Raid 1 was developed in the late 80's, and does exactly what you're trying to do. It maintains a 'copy' of the same data on two or more drives, in the event of the failure of one.

Yes, of course that's an option but I'm far from an enterprise operation with a ton of resources. That's a 486 on the desk behind the dog (lol-circa 1992)

Ironically Raid 1 may be too complicated compared to quantum .

Raid is very fragile from what I can tell even though the failure rate of ssd drives is low, about 1 in every 3300 drives . But any breaking the mirror risks loosing the data. I would be relying on three drives to work mechanically together with the RAID controller. If any one of those items has a problem, the array may fail. If one drive has a problem even for a moment, you have a degraded array on your hands and must rely on the RAID controller for error correction and array management.

Perhaps I am being naive about quantum machines which will likely have their own risks but the operation might be simpler in a quantum machine.Quantum mechanics would simply port the change between drives which could even be in separate machines in the same room.

You should read up on the difference between raid 0 and raid 1,the one does what you said the other does what osiris said.
That quantum thing you are looking for will probably take ages to be developed,if ever.

he said raid 1 dude.......

I don't think quantum computing even has anything to do with this lol.

Which brings an interesting thought, storage - perhaps even ram, is probably the biggest bottleneck in quantum computing. With the amount of data the NSA/other gov agencies need to store, I imagine they do use spindle drives, or do they have something even better? Though I guess they probably only really use quantum computers for cracking encryption, so data storage is not as huge of an issue, they probably use some kind or battery backed up ram based storage or something to store the temporary data they are trying to crack.

It's nothing exotic, just rows upon rows of racks with storage arrays and tons of CPUs, GPUs, and ram, just like any other server room. Gov's just tend to be a lot bigger.

You don't want quantum anything.....but I'll add some info to this conversation....and you won't like it. 😛

Any and all so called quantum computers are made to spec for specific hardware wired algorithims .
The most common use is encryption/decryption .
I won't bother to get into the math , I don't have the time.
I'll just leave this here : https://en.wikipedia.org/wiki/Quantum_annealing

You can't afford it and quantum computer is not designed to do this kind of jobs. 🙂

Raid 1 was developed in the late 80's, and does exactly what you're trying to do. It maintains a 'copy' of the same data on two or more drives, in the event of the failure of one.

Yep, RAID1 is basically just cloning write operations to multiple drives, with the added benefit the read operations are split across all cloned drives so read speed goes up with the number of drives. The controller itself on the motherboard takes care of managing the RAID devices and will react accordingly if one of the devices fails or becomes unreliable, so there's little to worry about there.

Honestly most reasonably decent motherboards these days come with RAID controllers on them, it's such an old and ubiquitous technology that it's actually fairly hard to find motherboards that don't support it, you need to be in the bargain section to find motherboards without it.

if the concern is reliability and you're comparing brand new ideas of quantum computing I can all but guarantee you that older tried and tested methods will be more reliable in reality than some kind of quantum system. reliability in the real world comes from years of R&D and testing products and then revising them, rinse and repeat.

reliability is actually one of the reasons I still use RAID0+1 at work rather than something newer and more clever, the moment you have to start dealing with parity drives and things like that, the more downtime you have repairing arrays and the more that can go wrong. RAID 1 or 0+1 gives you automatic fail over, since there's completely redundant disks inside the array at all times, if one dies it just alerts you and carry's on with the backup disks as normal, there's no downtime to fix either, it's fantastic.

Thx to all.
