With current solid state storage getting faster and faster, what do you think are the theoretical max speeds we will be able to achieve on current technology. Also, what do you think the next step in memory technology is?

Anonymous

Hi Dave and Tom. Everyone in tech media seems to be impressed with the SSD in the PS5. What are your impressions and thoughts on the technology of the SSD in the PS5?

Mican Andrews

Nice I would love to hear dave's input on the ps5 certain gddr6 memory chips running at 98c is it even a problem? Also why did it take Sony to move forward consumer memory controllers? Could no company make faster controllers for consumer before?

Brad Medlin

Hi Dave and Tom, 2 questions... 1) Will memory like Optane DC Persistent start to make more of use case in consumer/gaming PCs? 2) With things like CXL coming to PCIe gen 5.0, will we see more uses for things like Smart access memory or Resizable BAR in the future?

Happy New year Tom and to Dave, thanks for coming on. I saw it mentioned that storage was a topic and wanted to know if shingled magnetic recording is as bad for consumers as it was made out to be and would like your guys take on it. I’m of course referencing the controversy Western Digital found itself in, not too long ago. Thank you.

What do you think of the purpoted irrelevancy of High Performance memory, which focuses less on Capacity and more on Latency and Throughput? I personally find it rather odd how increasing capacity and decreasing power usage - server requirements - are the only market being served.

1) Gen 3 NVMe drives usually ran pretty warm, Gen 4 NVMe ones on the market now tend to be pretty hot. What's going to happen with Gen 5? 2) What do you think about the viability of memory technologies like MRAM? 3) DDR6 is rumored to use PAM4 which I presume will run incredibly hot and/or tremendously complicate PCB design. How long before we go to a serial interface like IBM's OMI?

Hey fellow former SanDisk Product Engineer here. I’m curious to hear Dave’s thoughts on whether we will see a slowdown in storage density increases on the consumer side as cloud continues to offload from local storage.

Cleansweep

Are there any upcoming technologies/processes that you (Dave) are excited about when it comes to storage, especially in terms of bringing their cost per GB down? As a consumer, $100 for a terrabyte SSD isn't bad, but it's not great for replacing HDDs as mass/archival storage.

Hello Tom and Dave. My question is for Dave, I see you have been on the product development field for quite some time now, I wanna hear your insight on how the paradigms for designing storage devices have changed throughout the years. What design choices have been prioritized trough the years and why?

I will answer this now: 98c isn't even remotely a problem. GDDR6 is built to run 24/7 at 100c or lower. Either it is too hot, or it isn't. It's a binary question for a console - if something is within spec, then it is within spec. Period. 100c isn't "cutting it close" either - 120c is when there is potential for damage (I believe this was the same for GDDR5). P.S. Ampere's memory runs hotter lol: https://www.tomshardware.com/news/report-why-the-geforce-rtx-3080s-gddr6x-memory-is-clocked-at-19-gbps#:~:text=For%20reference%2C%20Micron%20rates%20its,ranges%20between%200C%20to%2095C.

Hi, Two questions: 1. How did the memory's longevity change over time when the manufacturing process and the popularity on the market changed from classic hard-drives to solid state drives? 2. Do you think that with higher memory speeds every year the notebook designers would need to put more thought into developing dedicated cooling solutions for the NVMe SSDs?

Anonymous

Hi Tom and Dave, 1. Is there a future beyond current solid state storage? 2. If so can you give us an insight as to what it may be and the benefits it may bring? Thanks Dave for coming on the show.

Hello Tom, a while back you made took a deep dive in the playstation harddrive, and the future of hardrives. I love this podcast because of my interest in tech, the more I learn the more I know that I lack the basics. My question is maybe mostly for Dave. Could you give me a technical breakdown on the parts m.2 pci drive, how they work and what they do. In example. The old Samsung 970pro was MLC The new 980pro is TLC with a portion MLC. Is not TLC slower. And how do they make up for that with the other parts And while your at it. The marketing goes like this drive delivers up to 7000read/5000write. But I find it harder to make sens of the nubers, and what to look for to differnsiate the the drives from one another. Can I get some input to make this make more sens? Sorry for writing a 5 page essay :-) Can I ask one more thing though 😁 Since the fastest m.2 drives are slower then ddr2. Why does it not make sense to make a harddrive out of ram or at least a large portion of ram? Like 16 or 32 GB in example? Or 128 so i could load a game up in ram fast hardrive (not modern warfare of course, that game was a pentabyte last time I checked)

My question would be for optane as a medium in laptops. What workloads does intel optane make sense in a gaming laptop. For instance I have a rtx 2070, 64gb of ram crucial balistixs laptop with 1tbnvme and 2tb ssd, would replace one of the drives for optane improve performance in video editing or rendering? Or has current storage and memory speeds pretty much topped out until software starts to use it better.

Since samsung make 8 nanometer silicone, why is not the ram in 8 nanometer?

Anonymous

Since I am on a question spree. Why are gpu's using faster ram ddr6 then cpu's ddr4?

Chris Rijk

A question for Dave: Imagine a new games console launching in 2030. What would you best bets be for the main memory configuration? For example, something like today's consoles but just higher bandwidth and density. Some form of stacked memory like HBM? Or perhaps something completely different? Do you think DRAM will still be the underlying technology at the cell level even though it has stagnated a lot lately?

Different types of ram entirely. It's GDDR vs DDR they aren't interchangeable

Anonymous
>>50920712

There is an important wording change I need to make to your question, it's silicon not silicone, the silicone you are referencing is a rubber. I need to look more into the question before I can answer it as I don't know. The only reason I can say is that it's different silicon that serve different purposes.

With the evolution of 3D stacking on CPUs that are coming "soon" will we have L1 cache on the CPU that is more than 100 Megabytes?

Vipast

With Memory capacity and speed increasing, the integration sharing of assets among video cards, RAM, SSDs, and on-die Cache. What are the major bottlenecks between these components? Is it the I/O controllers, bus speeds, CPU, and/or software limitations (How bad is Windows holding us back?)?

Vipast

What really affects pricing when it comes to the types of memory used in SSD's? QLC vs TLC... etc (3D V-NAND,SLC, MLC, eMLC)

Vipast

Why is memory always in "slot" designs? Have there ever been any other attempts in different types of connection interfaces such as socketed memory? CPU's were at one time in a "slot" design and then went back to Socket.

Mostly software and consoles when it comes to gaming everything is optimized for the mass market

Thanks for getting such an interesting guest! My question is regarding the recent prominence of Cache. With AMD, (and Apple, if I'm not mistaken), it seems like a larger unified cache is at the center of a lot of breakthroughs in performance, but it seems to me like there would've been attempts at something like that in the past, so my question is: is there a reason why a larger unified cache is viable now where it wouldn't otherwise be? Thanks.

Hi Dave, As i Student for electronic engineering i was wondering when apple move the ram to be imbedded with the SOC in the M1 that must made the ram extremely low latency almost like another tier of "cache" do you think that the way they manage to remove the main bottleneck in emulating X86 to ARM since as i know the main bottleneck is store and load instruction. if that is the case how to you think they will fare in high end work station that require a lot of RAM for there operation? Another question do you think that the use in PAM4 signal in GDDR6X for GPU is the cause for the RTX 30 crushes ? Thank for answering my question

What is stopping the widespread adoption of Optane DC solutions in the DC? What does the end of the JV between Intel and Micron mean for the future of persistent memory?

KarbinCry

I've got a couple. 1. Could you do a short post mortem on HMC? Why did it end up losing to HBM? I know it was after Dave's time at Micron. 2. Are we now at the precipice of a shift to serial memory? And why did a parallel interface survive - and continue to survive - in memory, when all other high performance interfaces went serial decades ago?

KarbinCry

And some more from the fab side. 1. Can Intel spinoff their fabs? And can they enter the foundry market at all, given they failed miserably the last time they tried? 2. What is the future of GloFo? And what role will FD-SOI technology have going forward - could we see it used for bleeding edge nodes as shrinks and gate structure changes stop bringing enough improvements?

I have a question about ssd storage memory SLC, MLC, TLC and QLC are all different types of ssd storage memory with different storage densities As memory gets denser, it becomes less reliable and has less write endurance. It also has higher bit error rates Given this, why do companies, especially budget ssd manufacturers like Samsung with its Evo line of ssds, keep releasing new ssd products with higher storage densities when they know it will result in less reliable ssds to the previous generation, with a lower write endurance and lifespan as well as higher amounts of data corruption and data loss? Why do they discontinue the old, more reliable ssds when some buyers prefer them to the newer, less reliable ones? And why don't they warn consumers about the dangers of buying these ssds in their adverts and on their websites? For Samsung especially, how worried should buyers of their latest Evo line of ssds, the 870 Evo which uses QLC memory, be about write endurance, product lifespan and data error rates? Should the Evo line be avoided if say a computer user hibernates their computer at the end of each day, writing tens of GBs of data to the ssd each time, and does this for a few years, while continuously filling up their ssd every day with more things, until it is full? Also how much more reliable and long life is Samsung's PRO line of ssds, and which out of all of the available ones is the best for reliability and has the least data errors? Same question for the Evo line Finally, SSDs that use NAND Flash memory will slowly leak charge over time if left for long periods without power. This means they will start losing their data after one to two years. SSDs are therefore not suitable for storing data for long periods of time, whether they are left on a shelf outside a computer or in an old computer no longer used. Why isn't this fact made clear to consumers on ssd manufacturer websites and computer adverts? And what efforts have been made to make an archival quality ssd that also has great read and write speed and high write endurance?

One more thing When will we be seeing ssds with rgb lights in them :)

Hello Tom and Guest, recently PC hardware performance saw solid improvements: storage got a lot faster with Gen 3 and 4 NVMe SSDs, but CPU development didn’t stope either, looking at Zen 3 and what’s around the corner. My Question is regarding the gap between storage speed and CPU speed: is it increasing or does storage catch up. Im especially curious about how soon we can use some of the PS5 SSDs technology in PC Land and what performance gains it will enable, apart from gaming.

Something about ram memory Why is ECC error correcting ram only available for workstation computers? Why isn't error correction in consumer and gaming ram and why don't those motherboards support it? Why do ram makers think consumers and gamers don't want error correction? Another question Most gaming computers come with 16GB or 32GB of ram. How many years will it be before gaming computers typically come with 64GB or 128GB of ram? Another Why is the fastest laptop ram available today so much slower than fastest desktop ram? The fastest laptop ram at the beginning of last year was 2666Mhz and it's only recently gone up to 3200Mhz The fastest desktop ram is 4800Mhz

Although it's too late to ask for the video, I'll put it here anyway Hard disk drives work by having a head read from and write to a platter. When the head touches or scrapes the platter, there's data loss and damage to the platter Although a home computer with a hard drive should always be kept on a stable surface and never bumped, knocked or shaken, that isn't always possible, especially if the hard drive is in a lightweight computer or laptop on a shared table in a family home What efforts have companies made to make consumer hard drives vibration proof, knock proof and shake proof, and how far will it go and can it go? Which consumer hard drives available today are the most resilient to vibration, knocks and shakes when reading from and writing to?

Have you ever been a mac user? Is there anything from the apple ecosystem that is of interest to you? Especially on new M hardware and so.
