Frequently Discussed Topics
Q: Which SSD is faster for gaming?
A: The Kingston A400 offers slightly better 4K random read/write speeds, which can benefit gaming performance.
Q: How much storage capacity do I need for everyday use?
A: For typical computing tasks, a capacity of 240GB or 480GB should be sufficient.
Q: What is the difference between SLC and TLC NAND?
A: SLC (Single-Level Cell) NAND stores 1 bit per cell, while TLC (Triple-Level Cell) NAND stores 3 bits per cell. TLC NAND is more cost-effective but has lower write endurance.
