存储市场持续供不应求，本周各类产品价格继续上涨势头。 随着原厂合约价的大幅上涨，现货市场的价格显得更加疯狂。 存储价格的大幅上涨，已经彻底影响到消费电子的整条供应链。 无论是手机厂商、电脑厂商、电动车或者服务器等产品，都在感受着缺货和涨价的双重压力。 不出意外的话，接下来市场上的手机、电脑和显卡价格都将有所上涨。 由于产品全面涨价和供应受限，市场成交量下降，整体成交订单陷入低迷。 另外，部分产品的报价已经翻倍，虽然很多厂商存在需求，但碍于价格过高，只能暂时维持低库存的局面。 DRAM模组销售，已经变为买模组，要搭配主机板，形成配货制。 模组厂受到上游资源涨价，原定于第四季度发布的新产品，目前都已经全面推迟，2026年才会推出。 供应链的各个环节都在观察价格的走势，暂时无法确定未来的产品规划和采购决策。 一方面供应紧张和资源不足，另外一方面，暂停报价和控制接单，市场情况比较混乱。 具体产品方面，DRAM价格继续大幅上涨，现货颗粒价格剧烈波动，成交活跃。 SSD产品价格持续上涨，交期持续延长，出现有价无市的现象。 Flash Wafer市场，原厂合约价全线上涨，现货资源非常紧缺，报价已经翻倍。 USB市场，报价上 ...

Core Viewpoint - The article highlights the significant yet often overlooked contributions of Indian inventor Nasir Ahmed, particularly his development of the DCT algorithm, which has become foundational in digital image and video compression, impacting global communication and technology [1][9]. Group 1: Historical Context of Indian Software Industry - In the late 20th century, India's software industry was highly regarded, with companies like InfoSys setting the standard for software outsourcing and achieving high CMM certification levels [1][2]. - During the early days of software outsourcing, Indian firms were seen as leaders, while Chinese companies were still learning from them [1][2]. Group 2: Development of DCT Algorithm - Nasir Ahmed conceived the idea of image compression in 1972 while working as a professor in the U.S., despite facing financial challenges and skepticism from peers [2][3]. - The DCT algorithm allows for significant image size reduction (up to 10:1) while maintaining visual quality, revolutionizing how images are stored and transmitted [6][7]. Group 3: Impact of DCT on Digital Communication - The DCT algorithm became integral to various digital formats, including JPEG for images and MP3 for audio, enabling efficient data transmission over the internet [7][8]. - Without DCT, modern digital communication, including video calls and social media sharing, would not be feasible, highlighting its critical role in the digital age [8][9]. Group 4: Recognition and Legacy - Despite the widespread use of DCT, Nasir Ahmed remained relatively unknown and did not seek patents or commercialize his invention, focusing instead on academia [9][10]. - The article emphasizes the importance of foundational innovations like DCT, which, while not always recognized, have profound effects on global connectivity and technology [10][11]. Group 5: Indian Innovation Culture - The article discusses the Indian approach to innovation, which often emphasizes deep technical research over quick financial gains, as exemplified by Ahmed's work on DCT and the invention of USB [10][11]. - This culture of perseverance and focus on foundational technology has led to significant contributions to the digital world, despite the perception of India as primarily a service-oriented economy [11][13].

Core Viewpoint - The article discusses the evolution and various standards of USB technology, highlighting the importance of understanding different USB protocols and their corresponding performance indicators. Group 1: USB Evolution - USB was introduced in the late 1990s as a universal interface, replacing multiple types of ports and significantly changing computer usage [1] - USB 2.0, released in April 2000, offered a transmission speed of 480 Mbps, a substantial increase from USB 1.1's 12 Mbps, making it suitable for high-bandwidth peripherals [5][6] - USB 3.0, launched in November 2008, increased the maximum speed to 5 Gbps (625 MB/s), marking a significant upgrade over USB 2.0 [9] - USB 3.1 Gen 2 doubled the speed to 10 Gbps (1250 MB/s) in 2013, with further updates leading to USB 3.2 Gen 2x2 supporting 20 Gbps [13][16] - USB4, introduced in 2019, provided a major upgrade with a theoretical maximum bandwidth of 40 Gbps (5000 MB/s) [19] - USB4 Version 2.0, launched in 2022, further increased the speed to 80 Gbps (10000 MB/s) [21] Group 2: USB Standards and Icons - USB Implementers Forum (USB-IF) created a set of icons to help users identify the supported protocols and performance of USB ports [2] - The USB PD (Power Delivery) standard allows for power delivery of up to 100W, with the latest version supporting up to 240W [29] - DisplayPort Alternate Mode allows USB-C ports to support video output, but is gradually being replaced by USB4 and Thunderbolt standards [33][34] Group 3: Thunderbolt Technology - Thunderbolt is not USB but uses USB-C connectors and has cross-compatibility with USB, making it relevant for users to understand [24] - The latest Thunderbolt version supports speeds up to 80 Gbps, comparable to USB4 [25]
