Test Environment for Synology Applications

  • Synology Office:
    • Models are tested with their default memory configuration.
    • FS Series models are tested with 10 SSD drives configured into a single SSD volume.
    • SA, HD, and XS+ Series models are tested with four HDD drives configured into a single volume and two SSD drives as read-write cache.
    • J, Value, and Plus Series models are tested with up to four HDD drives configured into a single volume.
  • Synology MailPlus:
    • Models with SSD support are tested with up to 12 SSD drives configured into a single SSD volume.
    • Models with expandable memory are tested with their maximum supported memory, up to a limit of 64 GB.
    • The performance of the mail system will slightly decrease in high-availability mode due to data synchronization between the two servers.
    • Functions enabled during tests: anti-spam, anti-virus, DNSBL, greylist, content scan, full-text search (English only).
  • Synology Surveillance Station:
    • Performance figures are obtained from testing conducted with the device fully populated with drives, with their default memory configuration, and under a continuous recording setup. Actual system capabilities may vary based on configuration, drive performance, enabled features, and the presence of additional workloads.
    • FS Series models are tested with SSD drives while all other models are tested with HDD drives.
    • The performance metrics for SA6400 and SA3610 improve with the addition of expansion units. For detailed figures, please refer to this article.
    • For specific models, Surveillance Station 9.1.3 or above is required to support the performance figures listed. Please check the product software specification for details.


  • Performance measurements are conducted using numerous client endpoints with optimized network settings and manual traffic distribution. Your product performance may vary depending on configuration and environmental factors.
  • Performance testing for Synology applications is conducted without additional applications running on the system. Running multiple applications concurrently may impact both overall system performance and the performance of individual applications.
  • The availability of device models may vary by region. Please contact a local Synology partner for more information.
