Core Viewpoint - The article discusses the pricing and technology behind the new iPhone 17 Pro Max, particularly focusing on the controversial use of QLC (Quad-Level Cell) NAND flash storage in its highest configuration, which is priced at 17,999 RMB for 2TB, making it the most expensive iPhone ever [5][19]. Pricing Analysis - The starting price of the new iPhone is perceived as competitive, but the top-tier model's price has reached an unprecedented level, with the 2TB version costing 4,000 RMB more than the 1TB version [5][19]. - The article highlights the stark contrast in value, suggesting that the additional 4,000 RMB could buy several 2TB SSDs from other brands [5]. Technology Overview - The iPhone 17 Pro Max's 2TB storage option likely utilizes QLC NAND flash, which is a departure from the traditional use of multiple lower-capacity TLC chips [8][19]. - QLC technology allows for higher storage density but comes with trade-offs in terms of performance and longevity compared to SLC, MLC, and TLC [11][13]. NAND Flash Types - NAND flash types include SLC (Single-Level Cell), MLC (Multi-Level Cell), TLC (Triple-Level Cell), and QLC, with QLC storing the most bits per cell but having lower endurance and speed [11][15]. - QLC's lower endurance is highlighted, with a lifespan of approximately 1,000 write cycles compared to SLC's 100,000 cycles [15][16]. Performance Considerations - Despite concerns about QLC's performance, the article argues that for typical smartphone usage, the lifespan of QLC storage is sufficient, estimating that a 2TB QLC drive could last nearly 30 years under normal conditions [19][21]. - The use of SLC caching is mentioned as a method to mitigate QLC's slower write speeds, allowing for faster data handling in everyday use [23][24]. Market Implications - The adoption of QLC in smartphones may lead to more affordable high-capacity storage options in the future as supply chains mature [28]. - The article suggests that while consumers may initially be wary of QLC, its integration into devices like the iPhone could ultimately benefit the market by providing larger storage capacities at lower prices [28][29].

Core Viewpoint - The new iPhone 17 Pro Max features a top configuration with a staggering price of 17,999 RMB for the 2TB version, making it the most expensive iPhone ever, with a 4,000 RMB premium for the additional 1TB of storage compared to the 1TB version priced at 13,999 RMB [2][3]. Pricing and Storage - The iPhone 17 Pro Max's 2TB model is priced at 17,999 RMB, which is significantly higher than the 1TB model at 13,999 RMB, indicating a steep price increase for additional storage [2]. - The additional 1TB of storage in the 2TB model costs 4,000 RMB, raising questions about the value proposition given the cost of alternative storage solutions [2]. Technology and Specifications - The 2TB version likely utilizes QLC (Quad-Level Cell) NAND flash memory, which has raised concerns among users due to its lower performance and lifespan compared to other types of NAND flash [3][6]. - Apple has achieved a "world first" by using a single 2TB QLC flash chip instead of combining multiple lower-capacity chips, which is a departure from the practices of other manufacturers [6]. NAND Flash Memory Types - NAND flash memory types include SLC (Single-Level Cell), MLC (Multi-Level Cell), TLC (Triple-Level Cell), and QLC, with QLC being the least durable and slower due to its higher data density [8][12]. - QLC can store 4 bits of data per cell, which reduces costs but also leads to lower performance and lifespan, with QLC having a write endurance of only 1,000 cycles compared to SLC's 100,000 cycles [20][21]. Performance Considerations - Despite concerns about QLC's lifespan, calculations suggest that a 2TB QLC drive could theoretically last up to 30 years under typical usage conditions, as the total data written can be substantial [26][27]. - The use of SLC caching is a common method to mitigate the slower speeds of QLC, allowing for faster write operations by temporarily using part of the QLC storage as SLC [34][41]. Market Implications - The integration of QLC technology in smartphones may lead to more affordable options for consumers in the future as supply chains mature, potentially allowing for larger storage capacities at lower prices [45].
