Will Optane replace RAM and storage both?

1) DRAM is faster, your retarded mongoloid

2) Optane tech is way too expensive $/GB to be useful.

3) It will most likely be outshined in the near future by another solid state storage medium - maybe MRAM finally?

When are we going to have consumer ramdisks? Its beyond me how no company in 2019 makes pci ram enclosures with a battery, not even the chinese

>consumer ramdisks

Sounds expensive.
Something enterprize has, I presume.
What is it? Lots of RAM?

because it's not profitable to start selling RAM as both storage and working memory. That means SSD and hard drives and all the technologies used in servers goes to shit. And I'm looking at you infiniband, you worthless pile of shit.

No, not even close. Optane has, at best, the throughput of a DDR2 RAMdisk with added latency.
What will replace RAM is several hundred megabytes of LN cache.

Ram as a hard drive, super super fast reads and writes

>super super fast
Horrible choice, PCI SSDs already are more powerful than any CPU can manage. What kills speed is latency.

RAM runs on power. It would all get deleted whenever you have to restart the computer.

imo it's not the "ram" as in the sticks they care about selling it's that people who understand what it means to keep their OS or programs running in volatile memory are few and far between and there would not be a lot of use cases so it's not profitable to sell the cards

to use one you would have to be mindful you had to transfer your shit to and from the disk to use it and that even if battery backup powered it would be easy to lose all information there forever if power were lost even for 1 second

It would be great for workstations though, for power users

Maybe that's because the OS treats the SSD as a hard drive. Something something information packets and decoding.

>RAM runs on power. It would all get deleted whenever you have to restart the computer.
no shit

not really, the latency is also reduced, also all read and write including sequential and non sequential is very high no matter what with low latency

several hundred megabytes with replace several half-dozens of gigabytes

Something something it has to be completely backwards compatible with SATA or m.2

Testing VPN, have a bump

I don't see why not. You can just run on swap when SSDs get fast enough. Minimalistic android ROMs manage just fine.

>Something something it has to be completely backwards compatible with SATA or m.2
pci

>RAM
Not happening. You cannot replicate the latency and speed between RAM and CPU in an expansion port.

Ooops! PCI-e is not an expansion port. It's part of the local bus directly connected to the CPU.

What I mean is that from the computer’s perspective, an SSD is just a memory region that you can use to store data. So, an SSD can look like a regular HDD, or it can look similar to a RAM DIMM, in fact it can even be a DIMM (called a NVDIMM). So anyway, when the OS wants the CPU to tell the SSD to store data, the CPU sends data to the SDD in the same way it would send stuff to a HDD, and it's up to a chip in the SSD to decode this into SSD language. The SSD also needs to send a message back to the CPU when it's finished writing the data. This message must also be translated before the SSD sends it.

But what if the CPU always assumed it was talking to an SSD? It could send requests to the SSD in SSD language and there would be no latency incurred by the SSD decoding the message.

Interesing

I don't see this shit aging well in the long term.
Archival ssds when?

never
SSD have a set shelf life regardless of use, HDDs require frequent spinups/consolidation runs to keep the data.

>HDDs require frequent spinups/consolidation runs to keep the data.
wat

So everyone just rotates hdd and ssds? How long can a hdd even stay powered off? I've booted up pcs that sat for 10-30 years with no loss of data can't say the same about ssds I've seen die if I don't turn them on every day

lmao no, DC 3400MHz RAM has 54.4GB/s of bandwidth and can do close to 2GB/s of 4KB random read/write. Optane can barely do 2GB/s sequential and barely 0.2GB/s 4KB random read/write.

At BEST optane can be used as a glorified page file drive but given the cost it's better to just buy a 970 pro and use that instead.

you need to spin up the disk every 5 days for about 4 minutes and do a rewrite every 4 months if you want to keep the data as-is and still accessible at a moment's notice.
>How long can a hdd even stay powered off?
forever, but data won't be preserved and you may have issues with reads once you spin it up the first time, which is why you should do an undervolt spin-up on shitty old HDDs to make sure they don't wobble like shit. Most don't, but when they do, you get scarred for life by the sound it makes

Why is everyone still focused on this ram shit when massive terabyte caches are the future? Why is everyone fucking around with tiny 8 12 14 mb cache?

Am I getting memed again?
Who the fuck does this?
Rewrite every 4months seems overkill, I mean that would take several days for the 10 tb on my HDDs.

>you need to spin up the disk every 5 days for about 4 minutes and do a rewrite every 4 months
Fuck off already, my 15 year old PC in the basement hasn't lost a single bit of data.

don't listen to him. the magnetism on the platter is more resistant than that. however rewriting everything every year or two just in case wouldn't hurt

You should think twice before posting.

>Will Optane replace RAM and storage both
It isn't designed to do that.
It's slotting in between the two to act as another buffer, though it has the potential down the line to do so.

Conceptually, a medium that can be used as both RAM and storage like 3D Xpoint is very exciting, since it upends how we've done computing until now, cutting out the middleman as it were. It's just a matter of seeing if it will be the answer to this issue of datacenters needing more data faster, or a competing technology like MRAM (which Intel and others are also working on).

they literally just have to make a controller board, and I will install ram myself, I dont understand what is so expensive about that

>massive terabyte caches are the future?

Explain.
Caches of terabytes where?

I'm gay btw, not sure if that matters

Ok, but why do you eat up bait like there's no tomorrow?

>It isn't designed to do that.

Yeah, I don't know too much about whatever the 3D design is and if that's what's called Optane, and if that is the thing that will develop bigger and faster than other SSDs.

just use zfs + ARC

I'm creaming myself at the thought of 2GB L3 memory at the end of next year

how

>I will install ram myself

I'm lost on what was proposed about the RAM.
RAM is super expensive and stores nothing when power goes off.
You want to use it to do what now?
Do what different than by 16 gigs of DRAM are doing now?

(I'm not naysaying anything, I just don't know what's being proposed. I'm just a caveman. Your world frightens and confused me.)

Configure Linux or your BSD kernel to boot with ZFS filesystem support and run your / and other filesystems on the ZFS pool(s). Have a bunch of RAM on your board and stuff will get cached there for read/write. It won't be as fast of a boot as your ramdisk, but once stuff is cached it should be breddy gud.

Sorry I'm going to clarify/correct myself. Shit won't get cached on the RAM for write because obviously that would be a horrible idea. You could use a ZIL for that however but it still wouldn't be as fast as your DRAM. Sorry.

>not having 96GB MRAM as your main storage
pathetic

NRAM

3D Xpoint is a class of memory called "storage-class memory".
In a more perfect world, rather than a HDD or NAND loading the information to the RAM, and from there to the CPU, you would be able to load directly from the storage itself. We can't do that now, because DRAM is volatile and loses data when power is cut.
In datacenters, which hold vast databases that need quick access times or need to manipulate data as fast as possible, DRAM is used constantly as giant RAMdisks. Companies use huge oceans of RAM to do this. But the RAM is expensive, and since it's volatile, they need to jump through hoops and add complexity to make sure nothing goes wrong.
Storage class memory is a more elegant solution to these problems. It isn't as fast as DRAM, which is why it can't totally replace it, particularly for mass market consumers, but for these larger companies working with large amounts of data that needs to be worked with quickly, it can offer a cheaper alternative that may be "fast enough" for their needs.
3D Xpoint (PCM) is one type of SCM. But there are alternatives like MRAM which have the same sort of potential.

Never heard of it.
I have 16GB of DRAM
1TB Samsung SSD
4TB old timey spinning disk HD.

I never heard of this MRAM on shopping sites or hardwareporn videos.

Interesting. But I don't understand.
You put thousands of these on the wall to get to 96GB?

Is this a running gag on Jow Forums?

Ya got me.

what are you quoting that for exactly?
you didn't typo, don't know what he greentexted that for

I guess if you insist it's normal to tell his retarded mongoloid that DRAM is faster (maybe he has a slow son or daughter to look after, nothing wrong with that), I'm not really in a position to disagree.

it's a memory module that's great for embedded purposes. It's just kind of not in a good spot commercially as of right now
