A field technician is replacing the 2.5-inch 5400 RPM SATA hard drive in an ultrabook. The system has an open M.2 slot that supports both SATA and PCIe/NVMe devices. The traveling user wants noticeably faster boot times, quicker application launches, and better resistance to accidental drops. Which replacement option will BEST meet all of these requirements because it uses non-volatile flash memory and communicates directly over the PCIe bus?
An M.2 NVMe SSD stores data in flash memory with no moving parts, providing strong shock resistance and dramatically lower latency than mechanical drives. Because NVMe leverages the high-bandwidth PCIe interface, it delivers much higher throughput than either a SATA SSD (limited to 6 Gb/s) or any magnetic HDD/SSHD. The other options either retain spinning platters or are constrained by the slower SATA bus.
