Synology D4NESO-2666-4G 4GB (1 x 4GB) DDR4 2666 MHz Memory

The Synology D4NESO-2666-4G is a 4 GB memory module engineered to expand the system RAM in compatible Synology NAS units. It operates on the DDR4 standard with a clock speed of 2666 MHz, providing a direct upgrade for improved system performance and responsiveness. The module utilizes a standard 260-pin SO-DIMM form factor, making it suitable for the compact internal architecture of compatible Network Attached Storage devices. This memory is designed to enhance the NAS's ability to handle concurrent tasks, large file transfers, and data-intensive applications more efficiently.

As an unbuffered, non-ECC module operating at 1.2 V, it is optimized for low power consumption and stability within its intended hardware environment. Installing this module allows the NAS to support more simultaneous user connections, accelerate file indexing operations, and improve overall performance in demanding applications such as virtual machines or Docker containers. It is validated by Synology for use with select DiskStation and RackStation models from the 18, 19, and 20 series, ensuring seamless integration and stable operation without compatibility conflicts.
