TechSellerUSA supplies genuine Synology hardware - DiskStation and RackStation NAS systems, expansion units, memory upgrades and spare components for backup, file serving, surveillance and virtualisation storage.

DiskStation, RackStation and Expansion Units

DiskStation units are desktop NAS systems suited to small offices, workgroups and branch sites. RackStation models mount in a standard cabinet and are built for higher drive counts, redundant power and continuous operation. Expansion units add bays to an existing system without migrating data, which is the usual route when a NAS outgrows its chassis rather than its performance.

Drive Compatibility and Memory Upgrades

Synology maintains a compatibility list, and drives outside it may work but will not be supported - worth checking before populating an array. Memory upgrades matter more than most buyers expect, particularly when running virtual machines, Docker containers or Synology Drive for a large team, since these workloads are memory-bound long before they are CPU-bound. Browse our enterprise hard drives for NAS population, or contact us for a build quote.
