DSM and QTS create different daily experiences

DS925+ is centered on DSM, with integrated backup, Photos, Drive, snapshots and administration. The environment is deliberately consistent across Synology models and is a major part of the purchase.

TS-464 runs QTS by default, giving the administrator more applications, network options and expansion choices. This flexibility can be powerful but requires more decisions and documentation.

QuTS hero gives TS-464 a ZFS path

QNAP allows supported TS-464 systems to switch to QuTS hero, its ZFS-based operating system. QNAP lists higher memory expectations for features such as inline deduplication and recommends appropriate SSD design.

The operating-system choice should be made before production data is installed. Switching later is not a simple in-place toggle, and migration between QTS and QuTS hero needs a backup-based plan.

Processors suit different workloads

DS925+ uses AMD Ryzen V1500B with four cores and eight threads. It is strong for storage services, indexing and containers but lacks listed integrated graphics.

TS-464 uses Intel N5095 with four cores and Intel UHD Graphics. The iGPU makes it a more direct candidate for media conversion, while the Ryzen threads can favor concurrent general services.

Plex is the clearest TS-464 advantage

QNAP markets smooth video conversion and Plex identifies exact hardware compatibility separately. With Plex Pass and supported software, Intel UHD Graphics can reduce CPU load during transcoding.

DS925+ remains effective for direct play and library storage. Frequent conversion can be moved to an external Intel server while DS925+ retains DSM storage duties.

Built-in networking is similar, expansion is not

Both systems provide dual 2.5GbE. That is enough for many homes and small offices, and can increase aggregate capacity across multiple clients when configured appropriately.

TS-464 includes a PCIe Gen3 x2 slot and QNAP supports compatible 10GbE cards. DS925+ does not offer the same generic PCIe route, so buyers needing 10GbE should assess another Synology model or accept 2.5GbE.

M.2 slots have different software possibilities

Both have two M.2 positions. QNAP supports cache and storage applications under QTS/QuTS hero with compatible SSDs, while M.2 devices are not hot-swappable.

Synology supports cache and storage pools on DS925+ under its model-specific rules, with stricter compatibility requirements. Physical fit alone does not establish support on either system.

Memory configuration must be matched exactly

DS925+ ships with ECC memory and supports a defined maximum for its platform. This is attractive for a storage appliance and DSM’s supported configuration model.

Current TS-464 listings commonly use 8GB, while a legacy 4GB version also exists. QNAP’s official maximum and matched-module requirements should be followed, especially for QuTS hero or VMs.

Containers and VMs favor QNAP flexibility

TS-464 supports Container Station, Virtualization Station and PCIe expansion. The hardware is well suited to a compact technical lab when memory and storage are planned.

DS925+ supports containers through DSM’s Container Manager and can run useful services, but Synology’s emphasis is integrated applications and storage rather than broad hardware experimentation.

Expansion means different things

DS925+ can use DX525 to add five bays through a vendor-supported path. This favors users who want to keep DSM while capacity grows.

TS-464 can connect QNAP expansion units and add PCIe cards. QNAP’s broader expansion ecosystem can be powerful, but each unit and card has exact compatibility requirements.

Drive policies are not simply open versus closed

Synology’s current 2025 Plus policy gives more HDD and SATA SSD flexibility under applicable DSM versions, while listed devices remain the validated path and M.2 rules remain stricter.

QNAP supports broad third-party storage but maintains a compatibility list. In both cases, validate exact part numbers and firmware rather than relying on family names.

The complete system cost includes the software choice

TS-464 may need extra memory, a 10GbE card or additional SSDs to realize its technical potential. QuTS hero also changes storage planning.

DS925+ may cost more per hardware specification but can eliminate the need to assemble equivalent backup, photo and management workflows. Price the complete deployment and administrator time.

The exact-model verdict

Choose DS925+ when DSM, backup, Photos and supported bay expansion matter most. Choose TS-464 when Plex transcoding, PCIe networking, QTS/QuTS hero, containers and VMs are stronger priorities.

Neither choice removes the need for independent backup, UPS protection and tested recovery. The decision tool makes the tradeoff explicit.

A final choice should also account for replacement availability and administrator familiarity. When the NAS is a critical business service, the model that the team can restore confidently may be worth more than a feature that looks superior on the product page. Record the chosen operating system, memory modules, network card, drive models and recovery sequence before migration.

For a new installation, test backup and restore before moving the final data set. That validation matters more than a small performance difference between the enclosures.
