 So here's world's first 128-layer 4D NVME SSD. Hi. Hello, my name is Jedwuk. So here we are introducing our NVME SSD for our consumer market. It is based on our SK Hynex 128-layer 4D NAND. That's the first to launch the 4D, 128-layer. What does it mean 4D NAND? 4D means a 3D array, a standard 3D NAND, but with the addition of periphery on the cell. That's how we call it, the 4D NAND, 3D plus another dimension to it. What is an undercell? It's a periphery undercell. It's like a circuit theory, a circuit theory for the NAND flash. Instead of doing it on the side, we're doing it under the 3D array. That's why we call it 4D NAND. 3D NAND is already amazing, right? Yes. 4D NAND is going to change the world, and it is changing the world, and 4D NAND, it's going to be everybody's going to adopt this, or is it special? Yes. SK Hynex was the first to have this 4D NAND, but then, yes, it is periphery undercell. It's a common technology that I think eventually everyone in the industry will adopt it. So SK Hynex is, where is it from, where is it based? SK Hynex is based in Korea. It's been a market leader for this kind of stuff for a long time, doing memory for how long? SK Hynex is a major ERAM and NAND flash memory technology provider. We have our own FAP in Korea. So it's from the core of the technology, the NAND component, that's why we adopted it into the SSD solution. So we have been doing this for a long time. We are a major supplier to all the top companies, top OEMs in the world, from the PCOEM to server data center. So now today what we are doing here is we are spending our SSD portfolio to the consumer market. So how many terabytes do you manufacture per second? I mean, you do a lot of capacity, you do a lot of memory, how does it work? It's big machines. Oh yeah, it comes from the NAND, NAND FAP, the capacity, right? And then all those will transform into a solution, whether a mobile solution, SSD solution. You do SD cards or? We do EMMC, UFS, not SD card, we do SSD. So 128 later, is that the first one to do 128? Yes, we announced that mass production of the NAND component sometime mid last year, we were the first. 128 in the world of memory sounds like not so much, is it possible to do millions of layers? That's the limit. How's it going to happen? It actually is a lot, from where we come from, as you know, for the past few years we have been growing from 32 layers to 64, 32 layers, then 96, then 128. So at the Flash Memory Summit last year, we publicly announced it, there's a potential to go up to like 500 layers or even beyond that, but then that's really many years down the road that we are still not disposing of. Why is it so hard to add more layers? It's all about the fabrication process, you can think of like, you're building a very tall building, like to make it very high up, you really need to improve your fabrication process. The key thing is to make it reliable for mass production. So how much data goes on this? This platinum drive, it supports up to two terabytes. So two terabytes? Yes, and the gold NUEME supports up to one terabyte. So are we going to see like 100 terabytes and how soon? How many layers do you need to get to like hundreds of terabytes? 100 terabytes, yes, it will be coming, but then maybe in a little bit bigger form factor like this, but eventually it will come, but about when and how I think that's still too far to predict. Is there a time when SSD becomes cheaper than hard drives? Or is it never going to happen? Also it's hard to say, I've been in the industry long enough that for a long time people have been setting that goal, but there's still a gap between SSD and HDD. But SSD, as a city vendor, we continue to improve our cost reduction year over year, generation after generation, but I try to give the best value to the consumer. Who provides the best R&D in this space? Are there like universities everywhere that contribute, the whole bunch of tech? Or is it all invented in South Korea, and that's it? I think it's a collaboration, I mean academia definitely play a big part in R&D, research and new technology. We collaborate with industry partners, with the university, with academia, so it's all around, it's the whole ecosystem. We work together. And is Samsung a competitor, or they actually work with you on everything? I'm sorry? Samsung. Competitor? Oh yes, Samsung has the same drive, so yeah definitely competitor. Competitor, alright. So what is this? This is just a demo, like we put our SSD into a gaming system, and then running some live benchmark. So you can see our platinum SSD is in there, and better in there. So there's nothing better than platinum, you don't have like diamond line? Maybe in the future. Maybe. But right now no, platinum is a high end. And the solid-state gold? So the most excited people about this are like high-end video editors, or gamers, or who? We are definitely targeting for, yeah, you name it, gamers, video editing, like those that require the high capacity, high performance, this is what we are providing to our customers. Because the point is not just capacity as a performance, it's at the main point. Yes. So this is the fastest performance? Yes, we optimize the performance, we own all the end-to-end technology. The DRAM, the NAND, the controller firmware. So that's how we provide to our customers. How fast does it get? You can see from the brochure here. What SSDs? Up to 3,500 megabytes a second for read, 3,200 for write. That's very fast. Yes, yes. Definitely one of the... And all this crazy fast speed is reliable forever. How long is it going to last? Oh, yes. I mean, when we design our drive, that's our spec, and we will... What's the warranty? Warranty is five years. Five years is pretty good. What's that? It's pretty long. SSD. So maybe in the early years there were some reliability issues, but that's been fixed. Our drive is we have shipped to many B2B, like OEM customers also. So we are very confident on our lightweight. Five years. Is there like a limited number of writes? Yes, yes. Five years or... How many writes? Like here, you see here, 1,500 terabytes. Terabyte written, 1,500. So if it's one terabyte, that means 1,500 times. Is it two terabytes? Is it half as much? Or is it for the two terabytes? I think it's for the two terabytes drive. All right. So that's pretty much. That's a lot. Yeah. The consumer market, I think, is a lot. But hard drives have many more writes on hard disk or no? I'm not too sure. All right. Cool. Thanks a lot.
