Frequently Asked Questions
Q: Can I install an SSD in any laptop?

Q: Is NVMe faster than SATA?
A: Yes. NVMe drives are significantly faster than SATA SSDs, with speeds up to 7,000MB/s compared to SATA’s 550MB/s limit. However, you need an M.2 NVMe slot to use them.

A: Most laptops have built-in thermal management, so a heatsink isn’t usually necessary unless you’re using a high-performance Gen4/Gen5 drive in a compact system.
Q: How do I clone my old drive to the new SSD?
A: Use cloning software like Samsung Magician, Acronis True Image, or Macrium Reflect to copy your OS and files. Many SSDs include a license for these tools.
