12-Bay rackmount flash storage

The Synology FlashStation FS2500 is a 1U diskless NAS enclosure built for all-flash arrays. It targets small to medium businesses that need low-latency block or file storage for virtualisation, databases or email workloads.

Ideal for I/O-heavy all-flash deployments

Organisations wanting high random read and write performance with RAID F1 or standard RAID levels will benefit. Buyers who need 3.5-inch drive support, larger memory configurations beyond 32GB DDR4, or fibre-channel connectivity should look elsewhere.

AMD Ryzen V1780B quad-core processor

The 3.35 GHz base clock with 3.6 GHz boost and eight threads drives over 170,000 random read and 82,000 random write 4K IOPS. This CPU choice determines whether the platform can sustain your most latency-sensitive applications.

Questions about this item

How many SATA drives can the 12-bay FS2500 hold before I need another chassis?

The FS2500 accepts 12 SATA SSDs in its 2.5-inch bays, so the first capacity limit you reach under sustained use is the 12-drive physical maximum.

What are the noise and heat figures when the FS2500 runs 24/7?

Operating temperature range is 0°C to 35°C with 5-95% relative humidity; the 1U rackmount design uses internal fans to stay within those limits during continuous operation.

Which memory modules must I already own to expand the FS2500 beyond the installed 8GB?

You need DDR4 modules; the system supports up to 32GB total capacity.
