Frequently Asked Questions

Q1. Can these SSDs be used with older PC systems?

They may be usable if the PC supports M.2 2280 NVMe SSDs. However, even if recognized in a PCIe 4.0 or PCIe 3.0 environment, transfer speeds will be limited by the connection standard, and the maximum performance of PCIe 5.0 will not be achieved. Users are advised to check their motherboard or laptop specifications, M.2 slot compatibility, and BIOS/UEFI support before purchasing.

Q2. Which series should I choose between NM990 and NM1090 PRO?

For a main storage drive for the OS, applications, and games, where high speed and durability are prioritized, the NM990 series is recommended. For users who handle large amounts of RAW data, 4K videos, generative AI-related files, and production data, and who require DRAM Cache for high-load tasks, the Professional NM1090 PRO series is recommended.

Q3. Is heat dissipation necessary?

PCIe 5.0 compatible SSDs deliver high performance but can generate significant heat under heavy loads. To ensure stable operation, it is recommended to use an M.2 heatsink provided with the motherboard or ensure sufficient airflow within the PC case.

Q4. Can these be installed in laptops?

They may be usable with laptops that support M.2 2280 NVMe SSDs. However, installation might not be possible due to internal space constraints, SSD thickness, thermal design, or BIOS/UEFI compatibility. It is advisable to check the PC manufacturer’s specifications in advance.
