Synology FS200T 2026 overview update
With Computex 2026 only days away, Synology today released their last year's announced 2.5" 6-bay successor to the DS620slim.
Small Size, Big Performance
Named the FS200T, this 2.5" 6-bay device has advanced in the world of Synology, transitioning from a desktop DS series to the distinguished FlashStation lineup. Indeed, the smallest member of the entire portfolio is here to stay, now with a new name, category, and several upgrades.

: Prologue
Starting in late 2024 and extending through mid-2025, Synology implemented several changes to its business practices and policies that were not well received by the general public, particularly among home and small business users.
Specifically, we are referring to their HDD compatibility policy, known as the HCL 4.0, which was published on April 16th, 2025.

Announcement of the new restrictive HCL 4.0 disk compatibility policy
In short, the policy mandates the use of Synology-only drives for all new and upcoming X25 DS models, although some models are still accepting enterprise drives such as the HAT5300.
As anticipated, the restricted drive compatibility over the following six months generated significant negative publicity in various forms until the release of DSM 7.3 in October 2025.

DSM 7.3 introduced a new HDD HCL 5.0 disk compatibility policy
The new HCL 5.0 largely reverted the previous restrictions, restoring full compatibility for all desktop X25 models with both Synology and third-party drives.
However, it is important to note that there is no guarantee that Synology will not attempt to enforce similar policies again in the future, or that certain features* may not be supported when using non-Synology drives (as is already the case). For now, customers are free to use any drive size and brand within the desktop models as they prefer.
*Compatible Synology drive benefits
- Volume-wide deduplication (available with Synology SSDs)
- Drive firmware updates throught DSM
- Synology 1-stop techinical support
The reason for revisiting these past policies in an article about the new FS200T model is straightforward. The FS200T is a successor to the DS620slim, sharing the same form factor with minimal hardware changes.
Although the hardware remains largely similar, the name alone warrants a brief overview that could shed light on the future prospects of this form factor.
: FS200T naming
From Synology's perspective, the new FS200T introduces several changes compared to its predecessor. Moving away from the DS (Disk Station) series and adopting an FS (Flash Station) vertical form factor, Synology aims to position this compact device as an all-flash solution from the outset.
The previous DS620slim name clearly indicated it was a 6-bay model introduced in 2020, whereas the FS200T name now emphasises the CPU family and product generation, similar to the naming conventions used for the DP series.
However, this clarification does not fully explain the initial prologue. The key reason is that users unfamiliar with the Synology compatibility list might not realise that the FS models are compatible with both Synology-branded drives and certain third-party options.
All-flash delivers snappy, highly responsive performance
Supports 6 x SATA SSD 2.5" drives
Includes one 2.5GbE port and one 1GbE port, providing fast networking with failover support
Includes 4 GB of DDR4 SODIMM ram (expandable up to 8 GB)
Based on the updated HCL 5.0, the new FS200T is compatible with any 2.5" SSD on the market, but Synology will fully guarantee support only with Synology-branded SAT5200 series. Notably, compared to its predecessor, the FS200T no longer supports 2.5" HDD drives, only SSDs.

: Hardware overview
From a hardware perspective, the new FS200T features some internal updates, but nothing substantial. Although the device was initially expected to be released in 2025, Synology decided to launch it this quarter. Despite expectations that some further refinements to its specifications might occur, no such changes have been made.
All-flash design for quiet operations at home or in compact workspaces
The 6-bay FS200T continues to feature the announced Intel Celeron J4125 quad-core CPU. This is an improvement over the DS620slim’s J3355, but as an FS series model, expectations were higher for a more capable processor. With the new profile naming, future generations may see more significant upgrades.
Compared to the DS620slim’s two-core CPU and 2GB of DDR3 memory, the FS200T offers a quad-core setup with 4GB of DDR4 RAM, with an upgrade path to support up to 8GB of memory.
The FS200T preserves its compact size, with a depth of less than 18 cm, matching the external appearance of the DS620slim. It supports hot-swapping drives in all six bays. While the model is designed to operate silently and efficiently, the minimal noise—approximately 21 dB—originates solely from the single 80mm vent at the rear.
Miniature all-flash storage for enthusiasts
The rear of the FS200T maintains the same port setup as previous models, featuring dual USB 3.2 Gen 1 ports and LAN ports. The notable upgrade is the addition of a 2.5GbE port alongside the standard 1GbE port, aligning with the configurations on models like the DS425+ and DS725+.
The FS200T's compact size makes it an excellent desktop solution or portable device. Its all-flash configuration minimises concerns about data damage during transport and makes it suitable for mobile use, such as in a mobile home.
Its low heat output, minimal noise—around 21dB—and small form factor, combined with enhanced performance and improved network connectivity, position this NAS as a prime choice for home users, small office content creators, and enthusiasts.
In terms of power consumption, it averages approximately 25.5W during regular use and about 19.06W with complete disk hibernation. Actual power use may vary depending on DSM services and packages, which can affect hibernation and sleep states.
Weighing 1.4 kg, the FS200T ranks as the second heaviest in the X25 series, just above the DS225+ (1.3 kg) and below the DS725+ (1.5 kg). It does not feature M.2 NVMe slots, similar to other Synology models, and many competing units offer full NVMe configurations. However, its primary limiting factor is the upgraded 2.5GbE network interface.
Even with an HDD setup, it's possible to saturate the 2.5GbE connection, especially with SSD or NVMe arrays. Synology chose to focus on a reliable, tested 2.5" SSD setup, which runs cooler and provides more storage at a lower cost.

Extended Warranty Plus program
The suggested retail price in the US is $499, translating to approximately €500 in most EU countries. Like other models in this class, the FS200T includes a 3-year warranty, with options for Extended Warranty Plus (EW201) in select markets, extending coverage up to 5 years.
