Bonne nouvelle : depuis quelques années, il est possible d’ajouter des disques SSD M.2 d’autres fabricants pour étendre facilement le stockage. Voici les meilleures options.

Synology Hard Drives and SSD Comparison with Seagate/WD/Toshiba and More – Deal Breaker?

In recent years, Synology has steadily moved toward a more vertically integrated hardware ecosystem, and the arrival of the 2025 generation of NAS systems marks a significant escalation in that approach. With a much stricter verification process for compatible storage media—covering both hard drives and SSDs—Synology now appears to heavily prioritize its own branded storage. This shift has sparked widespread debate across the NAS community, particularly as many long-time users of Seagate IronWolf, WD Red, and Toshiba NAS drives find themselves increasingly locked out of certain key features like RAID expansion, hot spare assignment, and recovery operations unless using “verified” drives. What’s more, while some of Synology’s media are rebranded and firmware-modified versions of familiar drives from Seagate and Toshiba, the pricing and compatibility limitations often leave users puzzled—and frustrated.

In response to growing user concern, we conducted a comparison of Synology’s drive lineup against the current offerings from Seagate, WD, and Kingston—analyzing each in terms of price per terabyte, real-world performance, durability specifications, and availability. Drawing from direct benchmarking, manufacturer datasheets, and controlled NAS testing environments, this article aims to answer a key question: is Synology’s branded media actually worth the premium? While some users may welcome the simplicity of a one-brand ecosystem, others are understandably wary of higher costs, limited SKU availability, and the potential long-term implications of vendor lock-in. Let’s break down what Synology drives really offer—and where they fall short—compared to the tried and tested alternatives on the market.

Synology Hard Drives and SSDs – What Drives Are There to Buy?

Synology’s storage media catalog is divided across value, prosumer, enterprise SATA, and SAS hard drives, alongside both SATA and NVMe SSDs. While these drives carry the Synology name and firmware, they are not designed or manufactured in-house. Instead, Synology rebrands OEM hardware from established vendors: Toshiba for the enterprise SATA and SAS drives, Seagate for the value-tier NAS HDDs, and Phison-based platforms for SSDs. The internal firmware is customized by Synology to integrate tightly with DSM, and in some cases, to restrict compatibility to only their branded drives within the latest 2025 NAS systems.

The naming scheme makes it easier to distinguish between drive classes:

• HAT for SATA NAS hard drives

• HAS for SAS enterprise drives

• SAT for SATA SSDs

• SNV for NVMe SSDs

This segmentation aims to help users align their hardware with expected durability (e.g. workload in TB/year), power loss protection, and RAID integration. However, it’s worth noting that several of these drives are virtually identical to third-party counterparts—particularly in the HAT3300 and HAT3310 lines, which closely mirror Seagate IronWolf models down to mechanical structure and spec. Despite this, third-party versions of those drives remain incompatible with key RAID features on the latest Synology systems unless they are officially “verified.”

While Synology’s branding suggests ecosystem cohesion, it’s essential to recognize that their drive firmware is not engineered for general-purpose systems. These drives are optimized—and in some cases restricted—for Synology NAS environments. However, performance benchmarks show that Synology drives often perform equivalently or slightly below their third-party counterparts in synthetic and real-world tests. Moreover, price comparisons reveal a 5–15% markup on average in the value tier, and significantly higher deltas—often exceeding 30–40%—in the enterprise-class and SSD segments. Combined with regional supply inconsistencies and limited SKU availability, the value proposition of Synology-branded drives remains hotly debated, especially when identical hardware from Seagate or Toshiba can be purchased for less—if only the 2025 NAS series would support them natively.

Synology Hard Drives and SSDs vs Seagate, WD, etc – Price per TB and Value

When it comes to entry-level NAS hard drives, the price differences between Synology’s HAT3300 and HAT3310 series and their third-party equivalents—such as Seagate IronWolf and WD Red Plus—are generally modest. In most cases, the cost per terabyte (TB) stays within a 0% to 15% margin, with Synology’s versions sitting slightly higher. For casual or home users who just want a drive that “just works” out of the box and benefits from firmware-level integration with DSM, that small premium might feel justifiable.

But the story changes dramatically as we move into prosumer and enterprise territory. Drives like the Synology HAT5300 and HAS5300 series can cost 40%–50% more than Seagate IronWolf Pro, WD Red Pro, or Seagate Exos alternatives—despite sharing the same mechanical internals in many cases. These aren’t just marginal differences; when you’re building a multi-drive RAID array with 12TB or 16TB drives, that pricing gap quickly snowballs into hundreds or even thousands of dollars extra. And this is particularly frustrating when, for example, Synology’s 12TB HAT5300 (built on Toshiba hardware) costs nearly double what a comparable IronWolf Pro sells for, despite similar endurance ratings and warranty terms.

In short, while Synology’s drives are built on reputable platforms and do offer advantages like verified DSM integration and predictable firmware behavior, the value proposition becomes questionable—especially in higher capacities and enterprise deployments. For many users, especially SMBs and home power users deploying multi-drive setups, that extra 40–50% markup can be hard to justify. When the mechanical hardware is near-identical and the only major differentiator is firmware control, it’s no wonder many are pushing back against this pricing structure.)

Zoom in to see the results. IMPORTANT that you keep in mind that these SSDs and HDDs are different capacities and therefore direct comparison and correlation between their performance is not fair – I include these because I think it is important to compare the general gist of using Synology HDD media in a system and then alternatives, but measured with Synology’s in-system tools. Larger capacities mostly tend to yeald better results in any brand of drive (not a ‘do-or-die’ rule, but generally true).

Synology Hard Drives and SSDs vs Seagate, WD, etc – Performance

IMPORTANT – In the process of upscaling the test result images (as there is a lot crammed in, so I have included the slightly blurred ones here) but I and will replace these with upscaled versions as soon as possible.

When it comes to performance, Synology’s hard drives and SSDs generally stay within expected ranges for their class—but with some caveats. Most of their HDDs mirror the performance of the OEM drives they’re based on, particularly in the HAT3300 and HAT3310 lines, which perform nearly identically to WD Red Plus and Seagate IronWolf models. You’re looking at familiar specs here: 5400–7200 RPM spin speeds, ~200–280MB/s sequential transfer rates, and ~180TB/yr workload ratings. That’s no surprise, considering these are essentially Seagate or Toshiba drives with Synology firmware and branding. Where things start to scale up, like in the HAT5300 and HAS5300 series, the specs remain on par with their higher-end third-party equivalents. These drives offer 550TB/year workloads, 7200 RPM motors, and MTBF figures around 2.5 million hours—just like IronWolf Pro, WD Red Pro, or Seagate Exos. But Synology currently tops out at 20TB in both SATA and SAS drives, while the competition is already pushing 22TB, 24TB, and even 26TB models. So, if you’re planning a high-capacity build, Synology might already be limiting your options on sheer scale alone.

Performance parity continues with Synology’s SATA SSDs. The SAT5221 and SAT5210 series are very close in spec to Kingston’s DC600M drives, offering similar read/write speeds, IOPS performance, and endurance levels. The SAT5210 even pushes into ultra-DWPD territory, boasting up to 10,000 TBW and higher daily write thresholds, which is competitive in the enterprise space. If you need high write endurance and steady power loss protection, these drives tick the right boxes.

The gap, however, opens up in the NVMe tier. Synology’s SNV3400 and SNV3500 drives fall short compared to third-party NVMe SSDs like the WD Red SN700. While Synology focuses on endurance, PLP (power loss protection), and integration with DSM caching features, the performance ceiling on these drives is noticeably lower—both in terms of sequential throughput and IOPS. Capacities also top out at 800GB, while others offer 1TB and beyond with faster read/write performance. So if you’re after speed or larger NVMe caching pools, Synology’s current options may feel behind the curve.

SATA & NVMe SSDs – Synology vs Kingston

In short, Synology’s drives generally deliver solid, reliable performance that matches their third-party foundations—but the benefits of full DSM compatibility come with a trade-off. While the SATA range holds its ground, the NVMe lineup is due for an update if Synology wants to stay competitive against higher-capacity, higher-speed SSDs now widely available elsewhere. If performance is your main concern, particularly for NVMe caching or flash-heavy tasks, third-party options may be a better fit unless full integration is a must-have.

Synology Hard Drives and SSDs Guide – The Good and the Bad

In reviewing Synology’s lineup of hard drives and SSDs, it’s clear that the hardware itself is solid—built on trusted OEM foundations and tuned to work seamlessly within DSM environments. From a compatibility and reliability standpoint, these drives do offer advantages, particularly for users who want an integrated, no-hassle deployment. That said, these benefits come with notable trade-offs. In many cases, Synology’s drives are mechanically identical to models from Seagate, Toshiba, or Phison, yet priced significantly higher—especially in the enterprise and NVMe tiers. While some of that premium may be justified by firmware-level integration, PLP, or simplified support paths, the cost disparity is hard to ignore for experienced users already comfortable with third-party hardware.

Ultimately, the decision to adopt Synology-branded drives will depend on your priorities. If you’re building a system where out-of-the-box compatibility, long-term support, and unified ecosystem control are paramount, Synology’s media may be a safe bet—albeit at a higher packaged price. But if your focus is on maximizing performance per dollar, scaling capacity, or customizing your setup beyond Synology’s verified list, third-party alternatives remain the more flexible and cost-effective choice. Until Synology expands their verified media list and adjusts regional pricing or availability, many users will continue to see these drives not as a value-add, but as an imposed requirement.
