Synology D4ES01-16G 16GB DDR4 ECC UDIMM SODIMM

Give compatible Synology systems the memory headroom they need for sustained business workloads. This 16 GB DDR4 ECC unbuffered SODIMM is designed for compact platforms that require dependable memory expansion with built-in error correction. ECC support helps maintain data integrity by detecting and correcting common memory errors, which is especially important in storage appliances and edge servers that run continuously. The unbuffered SODIMM design keeps the module suitable for systems that need efficient, space-conscious memory without moving to larger server-class DIMMs. At 16 GB, this module is a practical fit for environments that have outgrown entry-level memory allocations. It can help improve responsiveness during file services, backup operations, indexing, and other concurrent tasks. For procurement teams and infrastructure owners, choosing platform-matched Synology memory helps reduce compatibility risk and supports predictable performance over the life of the system.
