Absolutely. I keep saying to people "it doesn't matter, everything is fast now".
Gigabit fibre to the home, NVMe that is way faster than RAM was not that long ago, CPUs in phones that make old desktops look like toasters.
The disconnect is that the numbers feel huge in comparison, and what my computer can do for me really, is not hugely different.
- DaiPlusPlus 4y ago> NVMe that is way faster than RAM was not that long ago Citation?
- rektide 4y agoDDR2-1066 was pretty rare (fast), and rated as PC2-8500, meaning 8.5GBps. DDR3 started here-about, in ~2007. Consumer PCIe 5.0 ssds will in some cases likely surpass that.
- jakogut 4y agoDDR2-800 has a maximum theoretical bandwidth of 6,400 MB/s, and was in common use well after 2010.
- doubled112 4y agoDepends on what you consider a long time, maybe. https://www.samsung.com/us/computing/memory-storage/solid-state-drives/990-pro-pcie-4-0-nvme-ssd-2tb-mz-v9p2t0b-am/ https://www.samsung.com/us/computing/memory-storage/solid-st... > Sequential read/write speeds up to 7,450/6,900 MB/s https://en.wikipedia.org/wiki/DDR2_SDRAM https://en.wikipedia.org/wiki/DDR2_SDRAM Lists DDR2-400 capable of 3200 MB/s of throughput.
- ciupicri 4y agoYeah, but there's a random in RAM and SSDs aren't that great yet.
- DaiPlusPlus 4y agoNot to mention deletes/overwrites.
- tester756 4y agoSeems like we'll start using NVMe as RAM, so we'll be able to have higher RAM sizes
- rhn_mk1 4y agoIt's called swap.
- doubled112 4y agoCould we go full circle and use that for a RAM disk?
- sidpatil 4y agoIIRC tmpfs already does that, by swapping to disk.
- tester756 4y agoConceptually? yes, but I meant using NVMe fully as RAM, without your RAM sticks.
- godelski 4y agoIsn't the issue endurance? I'm pretty sure your drive would die before the year is over. Probably a month or two.
- bravetraveler 4y agoLatency would be significant as well Endurance may surprise you, but then again - I haven't paid much attention to newer (cheaper/weaker/more dense) NAND types
- Night_Thastus 4y agoIsn't NVMe storage much higher latency than RAM, which is no good for the CPU? IIRC, NVMe is also poor at random access.
- kiratp 4y agoLets all keep in mind that a very small portion of the global population has access to this. It is our responsibility to bring all of humanity forward with us as we write software. https://perfnow.nl/speakers#alex https://perfnow.nl/speakers#alex
- SketchySeaBeast 4y agoWhile you're not wrong about the portions who can access it, I wonder at how many of us doing work that brings humanity forward at all. Sure, let's not use fast system as an excuse for bad code, but I'm not going to pretend my CRUD app is elevating humanity. Even the stuff that claims to feels like at best a lateral move a lot of the time.
- rnk 4y agoThat kind of reads like a sarcastic post. The us has so much terrible internet. I'm about to try trip channel bonding starlink, dsl, and an lte internet connection. Starlink and dsl drop packets a lot. I'm in the us, pay $100 a month to get 5 mbit dsl. This is not in a big city though, 20 miles outside of a city, next to a highway. There's fiber that runs by the street at the small subdivision this is in, kind of in the woods. The company that owns it refuses to connect us to fiber, instead preferring to put 100 homes on 5mbit dsl at far more profit. There's one big commerical user that paid for the fiber. This is the story of the us of course, I'm not unique. A family member lives on the other side of the country, he's closer to a big city but has the same problem.
- TheHappyOddish 4y agoThe important thing is you kept those damn socialists out of your country and let good old American free market forces solve the problem.
