Mass Storage: Device Drivers [top]

Understanding these drivers is essential not only for systems programmers but also for IT professionals and power users seeking to diagnose storage performance issues or choose compatible hardware. As storage technologies move toward CXL and computational models, the driver will remain a critical interface—but one that must adapt to blurring lines between memory and storage.

Many modern drivers are —e.g., a USB flash drive uses usb-storage + scsi_mod + sd_mod . Understanding these drivers is essential not only for

The evolution of mass storage device drivers reflects the broader trajectory of computer hardware: from slow, serial mechanical devices to fast, parallel electronic systems. While the primary function remains the same—abstracting physical media into a block device interface—the implementation has shifted from low-level register manipulation to the management of complex, hardware-accelerated memory queues. As storage media continues to evolve toward persistent memory (e.g., Intel Optane) and computational storage, drivers will likely evolve further, potentially merging the file system and driver layers to minimize latency even further.
