SSD CacheSSD cache, also known as flash caching, is an easy and cost-effective way to improve the performance of your Synology NAS.Synology CalendarSmall upgrade, big performance gainA relatively small SSD cache can dramatically boost the data writing and reading speeds of large HDD volumes. In in-house tests, adding SSD cache to an all-HDD storage array boosted random write and read IOPS more than 15 times, and cut average latency by up to 93%.

higher random read and write IOPS Two SSD cache modes for your use scenarioAre you seeking to improve the performance of a static web server or file server, to boost your indexing and database applications, or to speed up virtual machine storage? Choose the most efficient SSD cache mode for your application.Read-only cacheImprove random read performance when small files are frequently accessed and rarely modified.Read-write cacheImprove read and write performance when small files are frequently accessed, modified, and created.
Flexibility in SSD cache integrationMost Synology NAS support installing SSD cache using one or several of the following interfaces:Drive traysInstall 2.5" SSDs using regular drive traysBuilt-in M.2 SSD slotsInstall M.2 NVMe SSDs using built-in slotsAdd-on M.2 adapter cards
Install M.2 NVMe or SATA SSDs using add-on adapter cardsBuilt-in data loss protectionData on read-write SSD cache modules are protected against data loss by a RAID configuration. Users can choose to create a RAID 1, RAID 5, or RAID 6 setup. If an SSD fails and the RAID degrades, I/O operations are diverted to HDD and all data is written back to the source, ensuring data integrity and operational continuity.Advanced analytics with Synology SSDFull integration with Synology’s DiskStation Manager (DSM) enables lifetime analytics for each SAT5200 unit based on actual workloads:Timely Notificationsdsm_ssd_cache.lifetime_timely_pOptimal UseEasy monitoring allows you to make optimal use of each SSD.
