At a recent International Electronics Conference (IEDM), Toshiba Storage released flash memory products based on Twin BiCS technology and revealed upcoming XL-Flash technology information, while saying it was not optimistic about the prospects for stacking storage solutions such as 3D XPoint.
As for the reason, Toshiba believes that the cost of the 3D XPoint is too high, and that it is difficult to match 3D NAND technology in terms of capacity/price ratio, and that 96-tier stacked flash memory is now on the market, making it easy to crush 3D XPoint on capacity.
In fact, for high-end DIY players, 3D XPoint is the perfect choice if they are looking for extreme speed and experience. Even the strongest SLC in NAND SSD can’t even see the proud taillights in terms of 4K random performance and latency, after all, one is DRAM and the other is NAND.
The current Intel 900P 280GB price is about 1799 yuan, if the market has SLC SSD products, 280GB capacity model solder is not cheaper than AoTeng.
Say XL-Flash, which is based on Bics Flash 3D NAND technology and SLC, with a latency of 1/10 of the current TLC flash, with transmission speeds between DRAM and NAND Flash flash. XL-Flash flash has a single Die capacity of 128Gb, supports 2, 4, 8 Die packages, and can be 32GB, 64GB, 128GB of single-grain capacity.
