Answers
D.
2.5in (6.35cm) SSD connected via SATA interface
Suggested answer: A

Explanation:

The best option that the technician should choose for the best performance is

A) PCIe SSD connected via NVMe interface. This option means that the technician should install a solid state drive (SSD) that uses the PCIe (Peripheral Component Interconnect Express) bus and the NVMe (Non-Volatile Memory Express) protocol to communicate with the motherboard. This option can offer the following advantages:

Faster speed: PCIe SSDs can transfer data faster than SATA or IDE SSDs, as they use more lanes and have higher bandwidth. PCIe SSDs can reach speeds of up to 7,000 MB/s, while SATA SSDs are limited to 600 MB/s and IDE SSDs are even slower12. NVMe is a protocol that is designed specifically for SSDs and can optimize their performance by reducing latency and increasing parallelism3.

Smaller size: PCIe SSDs can be smaller than SATA or IDE SSDs, as they do not require additional cables or connectors. PCIe SSDs can come in different form factors, such as M.2 or U.2, which can fit in

different slots on the motherboard12.

Higher reliability: PCIe SSDs can be more reliable than SATA or IDE SSDs, as they have less moving parts and are less prone to mechanical failures or data corruption. PCIe SSDs can also support features such as error correction and wear leveling, which can enhance their durability and lifespan12.
