Will SSD speeds catch up to RAM speeds and make it obsolete in the next decade?

Why not just replace ssd with 1tb of ram?

>Because it doesn't need to be erased at high voltage (which deteriorates the flash cell with every cycle) every time it's written to.
Why don't they make SSDs that don't need to be erased at high voltage?

Because otherwise they wouldn't remain their memory when you turn them off.

mom why is the sky blue
why is the grass green
why do we have to go to grandma's

>SD card
Sigh.

Those things exist, but at higher capacities they're still much more expensive than SLC SSDs of similar size.

So this is Jow Forums, people not knowing the basic of how computers work.

>everyone is supposed to be an electrical engineer
So what do you know about civil and aerospace engineering?

>civil enineering
Just build a bridge that doesn't break
>aerospace engineering
Just build a plane that doesn't crash

Am I hired?

99% of the board is technology related to computers/electronics.

Kids in secondary school learn how computers work these days.

One would think people know the basic. Don't need a degree in EE for that. Knowing you lose data stored in your memory when you turn off your computer.

>>everyone is supposed to be an electrical engineer
This isn't electrical engineering.

Why hasn't SRAM scalable enough to replace DRAM

Not gonna spoonfeed you, it's literally elementary school tier.

Compact Flash card

>power cut
>lose 400gb of irreplaceable dolphin porn

>not having UPS

then you would have to use a live cd or live thumbdrive, and boot/install the OS fresh every time you boot/reboot, while that is possible it would be a lot of extra work updating and installing your preferred software on every boot,

that is how thin stations work (sortof) but the server that holds the OS for a LAN full of thin stations keeps an updated copy of the OS that gets distributed to each thinstation

That's cool.

But they already do user, just buy lots of ram and setup a battery powered RAM disk.

What is this called?

which one is more expensive now? brand new SSDs or second hand DDR1 RAM?

A scam.

Why? It seems to work as regular RAM + a lot more storage capacity as non-volatile memory, so why wouldn't that work? The computer would be unaware of it.

shut up, faggot. completely irrelevant.

even cfast cards are not as speedy as dd2 ram

The real question is when will magnetic tape become a viable consumer (normie) storage option again?

No because even if the read/writes were the same as RAM its a different kind of memory thats designed to store data after power is switched off.

DRAM is designed to hand constant read/write/cache flushing because its volatile memory. when the power is cut all data stored in ram is gone and needs to be reloaded from cold storage such as HDD or SSD

To many writes on an HDD or SSD and they begin to break down. If you had the same overwriting rates of RAM on your SSD it would fry within a month or less.

Random access and latency DRAM are massive fast over SSD like NAND based or even Optane Memories.

SSD like pure RAM will be thousands of times slow.

>knowing 7th grade physics requires an EE degree

No, because RAM will get faster too.
NAND isn't meant to replace RAM, the developmental goals are different.

Dedicated RAM drives usually have NAND backup or at least backup batteries.
Also, what's a UPS.

>7th graders are taught physics
Shut the fuck up.

Now comes the part where you did learn it in 7th grade, so everyone else is inferior, we get it. Shut up

I think Intel's Optane Persistent Memory stuff is kind of close, but even that buffers to the CPU with DDR4. The problem is that all the solid state solutions massively behind RAM on latency, longevity, and speed.

Thank you for answering that user's question instead of being an asshole. Not everyone knows everything especially when they're young. We all had to start somewhere

no, you have to explain how, you lazy fuck

How nice of you Satan

It does. Your computer downloads new ram as required.

>not just using sram for everything

why not make bigger cpu's with massive cache's.
bypass ram all together

Why not make even bigger cpu's with more cache AND built in storage and video so no need for a motherboard, memory, hard disk or video card?

and fit it on 7nm

SSDs need to reach the ~200,000+ IOPS of random 4KB read to match RAM performance. Currently something like a 970 pro NVME drive can barely push 12,000 IOPS of random 4KB read.

So it's gonna be a really long time before SSDs catch up to that especially with DDR5 inching closer to 100GB/s bandwidth in dual-channel mode. Though in most cases things like web browsing and loading vidya won't improve much if at all if you go from a 970 pro NVME drive to a ramdisk.

1gb l1 cache when?
I'm gonna play doom at several trillion fps and no one will be able to stop me.

*turns off computer once*
*loses all data*
heh... noting personnel, kid.

Won't affect fps, faster storage just means you can move 4KB blocks around faster, has nothing to do with being able to processing and drawing polygons.

Why not just make ram not lose data?

Yes from what Sony is larping about some sort of unified ram ssd cache hybrid I've been talking about for years

Attached: IMG_20190422_194947.jpg (950x632, 29K)

somehow that reaction pic still manages to express concern in the first frame and awe in the second.

Soon.
Unified cache ssd ram hybrids are in development and they are testing the waters with the Ps5 and xbox. Like they did with gddr5 back in the day.
Zen 2 already has a fuck huge cache.

Now if gpus had access to a very large fast cache we'd be seeing 1000fps+ assuming we get 8 core mcm gpus running 4ghz on 5nm

NAND will probably never be fast enough to replace DRAM. NAND isn't bit addressable like DRAM is, so even in theory if it was fast enough you couldn't make it work.

You would need storage class memory like Phase Change Memory (like 3D Xpoint AKA Optane). In theory, you could have an Optane drive that replaced both DRAM and your NAND/HDD.

the RAM is needful of doing the not replacing, sir

>Kids in secondary school learn how computers work these days.
Typing up your essays in Microshit Word isn't 'learning how computers work'. AFAIK the best they have is an AP course for java programming which, guess what, will teach you absolute shit as well. You are way overestimating the school system. At least if you're American. 95% of kids don't even know what RAM is, yet alone the various designs/uses/specialties of memory.

>Not everyone knows everything especially when they're Pajeets
there ya go

Why don't they just make SSDs with batteries in side of them?
