Breathe life into your PC

Goodram is unveiling a new generation of its popular SSDs for home and office consumer solutions. The CX400 gen.2 is a line of SSDs aimed at those looking for a reliable and significantly faster alternative to a traditional hard drive.

Feel the difference

If your computer is running slower than it was just a few years ago, replacing your HDD with an SSD is the easiest and cheapest way to change that. SSDs have easier access to data, making it faster for your computer to boot and load applications and therefore work faster.

Reliable 3D NAND

The Goodram CX400 gen.2 SSD offers best-in-class performance and reliability. The refreshed drive features 3D NAND Flash memory. Improved firmware ensures full data protection, integrity and security during daily use.

Security & warranty

The CX400 Gen.2 SSD is based on high-performance 3D NAND Flash memory. Thorough testing and the appropriate selection of components have enabled the creation of a high-performance and durable drive. The use of the highest quality components and extreme attention to detail is evidenced by the drive being backed by a 3 year limited TBW warranty.


* TBW (Total Bytes Written) – SSD durability, a parameter that determines the maximum amount of data that can be saved on a drive until the warranty expires. The TBW parameter is defined in the SSD product specifications.
