Samsung Electronics is reportedly planning to convert its Xian factory to produce 286-layer NAND flash chips by year-end, while SK Hynix aims to upgrade its Dalian plant to make chips with 240 or more layers, according to Reuters sources. Both companies are racing to boost advanced memory output as AI data center demand grows, while fending off rising competition from Chinese manufacturers such as CXMT and YMTC.
A security research team documented their process of dumping and analyzing firmware (version 3.4.2.2h) from the Eufy HomeBase 2 device, following up on earlier work examining a Eufy doorbell. Because the HomeBase's flash chip was soldered directly to the board with no exposed test pins, the researchers used spring clips and a Raspberry Pi to physically read the Winbond flash memory chip.
Comparing a 256GB SSD to a 1TB hard drive isn't a simple capacity contest, since SSDs retrieve data electronically from flash memory while HDDs rely on spinning platters and moving read/write heads, making SSDs significantly faster for booting and running programs. Whether 256GB is enough depends heavily on usage: it suits light users who rely on cloud storage, while heavy local file storage, creative work or gaming may require 512GB, 1TB or more.
Modern flash storage relies on NAND memory cells that trap electrical charge, with newer 3D NAND designs stacking cells vertically and packing multiple bits per cell to boost capacity while lowering cost per gigabyte. These improvements have made flash ideal for SSDs and portable devices, since it lacks the moving parts of hard drives, giving lower latency and better durability. However, flash remains fundamentally different from RAM, serving as persistent storage rather than the fast temporary memory a system needs while running.
