TerraMaster All-Flash Series Compatibility Guide: Practical SSD Buying Tips

I. What Is a Solid-State Drive (SSD)?

A Solid-State Drive (SSD) is a data storage device that uses flash memory chips—such as NAND flash—to store data. Unlike traditional Hard Disk Drives (HDDs), SSDs contain no spinning disks or mechanical arms.
This design gives SSDs significant advantages in read/write speed, reliability, and power efficiency, making them particularly well-suited for NAS (Network Attached Storage) and DAS (Direct Attached Storage) systems. SSDs deliver faster data access and higher system responsiveness, greatly enhancing overall performance.

II. How to Choose the Right SSD

When selecting an SSD, start by clearly defining your usage needs.

Capacity considerations:
For entry-level users, a minimum of 256GB is recommended as a system or storage drive to avoid running out of space. Users handling large datasets or frequent backups should consider 1TB or more to ensure smooth daily operations.

Interface and form factor:

SATA SSDs offer broad compatibility and are ideal for upgrading older NAS or DAS systems, with typical speeds around 500MB/s.

NVMe SSDs (based on PCIe) provide much higher performance, often exceeding 3000MB/s, and are recommended for high-performance NAS or DAS applications.

In terms of form factor, 2.5-inch SSDs are compatible with most NAS and DAS systems, while M.2 SSDs are more compact but require careful compatibility checks to ensure seamless integration and avoid performance bottlenecks.

Brand reliability and endurance:
Choose trusted manufacturers such as Samsung, Western Digital, or Kingston, known for stable quality and reliable after-sales support. Pay attention to the TBW (Total Bytes Written) rating—the higher the TBW, the longer the lifespan (e.g., 500TBW or more is recommended for heavy workloads). A 3–5 year warranty is also strongly advised.

DRAM cache:
SSDs with DRAM cache deliver better random read/write performance and are ideal for multitasking and high-concurrency workloads. DRAM-less models are more affordable but may show reduced performance in complex scenarios.

Always refer to the device manufacturer’s compatibility list to ensure the SSD meets specific interface and model requirements.

Recommended SSD Models

Western Digital – WD_BLACK SN850X
Optimized for TerraMaster all-flash NAS systems with multi-slot expansion, such as the F4 SSD, which supports four PCIe 3.0 x2 slots. When configured with four drives in RAID 10, the system achieves significantly improved sequential and random I/O performance while maintaining strong data redundancy—tolerating at least one drive failure (or more, depending on failure distribution).
This balance of performance and data protection makes it ideal for small studios running virtual machines, AI data preprocessing, and other high-frequency, high-concurrency I/O workloads. Combined with the WD_BLACK SSD Dashboard, users can seamlessly monitor drive temperature and health within the TerraMaster TOS system. When paired with the TerraMaster F8 SSD series, the intelligent cooling system provides dual-layer protection, effectively extending SSD lifespan.

Samsung – 990 PRO 2280 NVMe SSD
Perfectly matched to the TerraMaster D1 SSD Pro with its PCIe 4.0 x4 interface, fully unlocking the enclosure’s maximum transfer potential. With efficient thermal design, the system remains stable and smooth under heavy workloads. The 1200TBW endurance (2TB version) supports enterprise-grade 24/7 operation, while the DRAM cache enhances responsiveness for multi-user access—pushing TerraMaster professional performance to the limit.

Seagate – IronWolf 2280 NVMe SSD
Designed specifically for NAS environments, this SSD series features firmware optimized for network storage workloads and is officially recommended for use with TerraMaster F8 SSD and F8 SSD Plus (see the TerraMaster compatibility list).
The F8 SSD Plus features eight independent PCIe 3.0 x1 M.2 slots, each with a dedicated lane, enabling simultaneous multi-drive read/write operations without bandwidth contention. This architecture is ideal for SMB file sharing, data backup, and server deployment. Combined with TerraMaster’s vibration-resistant chassis design, the IronWolf’s vibration protection minimizes resonance risks during multi-drive operation. A 5-year limited warranty and Rescue Data Recovery Services, together with TerraMaster’s after-sales support, provide comprehensive data protection.

Kingston – KC3000 / SanDisk – Ultra M.2 NVMe 3D SSD
With a PCIe 4.0 x4 interface and M.2 2280 form factor, these SSDs fully support the four NVMe slots of the TerraMaster D4 SSD, enabling RAID 5 configurations that balance large-capacity storage and data redundancy—ideal for professional creative teams managing extensive media libraries.
With endurance ratings of up to 3200TBW (4TB version) and TerraMaster D4 SSD’s independent power management module, standby power consumption is reduced while sustaining continuous writes under heavy workloads, preventing premature SSD wear due to insufficient TBW.

Crucial – P2 2280 NVMe SSD
More competitively priced, and when paired with the TerraMaster D1 SSD series, it delivers broad compatibility on a budget.

Final Buying Tips

Match your SSD choice to your budget and device specifications by checking the NAS or DAS manual and firmware settings to confirm interface support and avoid compatibility issues. Always purchase from authorized channels and avoid unknown low-cost brands to reduce the risk of data loss.

By following these guidelines, you can select a high-value, reliable SSD that maximizes compatibility and performance across your storage system.

DAS Models: D1 SSD Plus，D4 SSD，D1 SSD Pro

A detailed compatibility list is available on the official TerraMaster website.

IV. Can an SSD Be Used as a System Drive?

Yes. Installing the operating system on an SSD significantly improves system responsiveness, including web access and application loading speeds. However, a single SSD cannot be used simultaneously as both a system drive and a cache drive.
An SSD can be dedicated solely to cache or used as a system drive, and RAID configurations can still be created to optimize storage architecture and overall efficiency.

Conclusion

Choosing the right SSD not only ensures compatibility but also dramatically improves the performance and reliability of your NAS or DAS system. We recommend visiting the TerraMaster official compatibility list for the latest validated models and selecting SSDs based on your specific workload requirements—unlocking a faster, smarter, and more reliable storage experience.
