The Maxio MAP1602 is a high-performance, DRAM-less PCIe 4.0 SSD controller designed for mainstream client PCs. Its most notable feature is the ability to hit high sequential read speeds of up to 7,400 MB/s, effectively saturating the PCIe 4.0 x4 interface without the cost of an external DRAM cache. Key Technical Features

“They sent an automated system diagnostic,” Lin corrected. “The ship’s AI, for its last ninety seconds of power, did nothing but repeat this one status line. Not a distress call. Not a log entry. Just: Maxio 1602. Full. Maxio 1602. Full.” She paused. “And then the hull breached.” 3,500 MB/s speeds
