➀ SSD endurance, measured in Terabytes Written (TBW), is crucial for determining its lifespan; ➁ The type of NAND flash (SLC, MLC, TLC, QLC) affects cost, performance, and durability; ➂ A high-quality controller can significantly enhance SSD performance; ➃ DRAM presence can boost sustained write operations; ➄ Random read/write speeds are more indicative of real-world performance in gaming and general use.
