Match each storage device type or interface standard on the left with its defining physical form factor or operational characteristic on the right.

U.2 SSDHot-swappable 2.5-inch enterprise drive form factor utilizing PCIe bus lanes
M.2 NVMe SSDCompact modular storage device connected via an M-key slot directly to the PCIe bus
eMMCIntegrated flash storage controller soldered directly onto budget mobile device motherboards
SATA Revision 3.0Internal host bus interface limited to a maximum theoretical bandwidth of $6\text{ Gbps}$

Answer

U.2 SSD pairs with the 2.5-inch hot-swappable enterprise PCIe drive form factor; M.2 NVMe SSD pairs with the compact modular M-key PCIe drive; eMMC pairs with integrated flash memory soldered directly to the motherboard; and SATA Revision 3.0 pairs with the internal bus interface capped at 6 Gbps throughput.

Each storage technology is correctly paired according to its architectural specification: U.2 provides hot-swappable 2.5-inch enterprise storage running over PCIe lanes; M.2 NVMe SSDs utilize an M-key connector for direct high-speed PCIe access; eMMC is soldered embedded storage for entry-level devices; and SATA Revision 3.0 is an internal storage interface capped at a theoretical maximum throughput of

6\text{ Gbps}

Step-by-Step Solution

Identify enterprise hot-swappable PCIe drive form factors.

Recognize that U.2 uses a 2.5-inch enclosure connected to PCIe lanes.

U.2 allows server backplanes to offer hot-swappable drive bays with PCIe performance rather than legacy SATA/SAS bandwidth limitations.

Identify compact modular high-performance drive interfaces.

Determine that M.2 NVMe uses M-key slots for direct PCIe connectivity.

M.2 drives with M-keying support up to four PCIe lanes for high sequential read/write operations.

Identify permanently integrated low-cost flash storage.

Associate eMMC with motherboard-soldered embedded flash memory.

eMMC is non-modular, non-upgradable storage commonly integrated into budget tablets and compact laptops.

Identify legacy SATA interface maximum bandwidth limits.

Link SATA Revision 3.0 to its maximum throughput threshold of 6 Gbps.

SATA 3.0 is fundamentally restricted by its controller standard to a theoretical maximum speed of 6 Gbps.
