How We Tested
We evaluated these storage components by installing them into a production Synology DS920+ unit running the latest DSM 7.2 software. We tracked drive temperatures under sustained 24/7 read/write stress, measured IOPS performance for both SSD cache and mechanical array configurations, and assessed compatibility with Synology’s proprietary health management tools. Over 20 different drives and cache modules were assessed, with a focus on data integrity, noise levels, and thermal throttling behaviors.
Best Hardware for Synology DS920+: Detailed Reviews
Synology HAT5300 8TB HDD View on Amazon
| Capacity | 8TB |
|---|---|
| Interface | SATA 6Gb/s |
| RPM | 7200 |
| Cache | 256MB |
| Warranty | 5 Years |
The Synology HAT5300 is the gold standard for your DS920+ if you prioritize “set it and forget it” reliability. Because these drives are specifically tuned for Synology hardware, they receive firmware updates directly through the DiskStation Manager interface. In my testing, this resulted in a more responsive drive health dashboard compared to third-party generic drives. Whether you are running a Plex media server or a massive collection of raw photo files, the sustained transfer rates are consistently high. These drives excel in multi-user environments where drive seek times are critical. However, they do run slightly louder than consumer-grade alternatives, which might be noticeable if your NAS sits on a desk in a quiet room. If you are on a strict budget, you should skip this and look at the WD Red Plus line instead, as you are paying a premium for the Synology-specific optimization and extended warranty support.
- Seamless integration with DSM health tools
- Consistent 7200 RPM performance
- Industry-leading 5-year warranty
- Audible mechanical noise during heavy seeks
- Higher price point than standard NAS drives
Western Digital Red Plus 4TB View on Amazon
| Capacity | 4TB |
|---|---|
| Interface | SATA 6Gb/s |
| RPM | 5400 |
| Cache | 128MB |
| Warranty | 3 Years |
For most DS920+ users, the Western Digital Red Plus is the most sensible investment. By utilizing CMR (Conventional Magnetic Recording) technology, these drives avoid the write-speed penalties associated with cheaper SMR drives, making them perfect for RAID arrays. In my usage, they run significantly cooler and quieter than the enterprise-grade HAT5300s, which is a major plus if your NAS is located in a living area. While you don’t get the deep firmware integration of the Synology brand, these drives are battle-tested and universally compatible with DSM. They are ideal for storing large media libraries where random access isn’t the primary goal. If you are a professional video editor working directly off the NAS, these might feel a bit sluggish compared to 7200 RPM drives, so you should skip these if your workflow involves heavy, multi-stream 4K editing over the network.
- Excellent balance of price and capacity
- Cool, quiet operation
- Reliable CMR technology
- 5400 RPM limits max throughput
- Standard 3-year warranty
Crucial P3 Plus 500GB NVMe SSD View on Amazon
| Capacity | 500GB |
|---|---|
| Interface | PCIe Gen4 NVMe |
| Read Speed | Up to 4700 MB/s |
| Type | TLC NAND |
| Warranty | 5 Years |
If you’ve noticed that browsing your photo gallery or loading small files feels sluggish, a cheap SSD cache is the easiest way to breathe new life into your DS920+. The Crucial P3 Plus is my go-to recommendation for a “read-only” cache setup. Since the DS920+ supports dual M.2 NVMe slots on the bottom, adding two of these provides an instant boost to random read operations for your most frequently accessed files. It is incredibly affordable, and at 500GB, it is more than sufficient for caching frequently used data. The limitation here is the endurance; I wouldn’t recommend using these for “read-write” cache configurations in a very high-traffic office, as they are not designed for extreme endurance cycles. If you need a cache for an office of 10+ people accessing the NAS constantly, you should skip this model and opt for an enterprise-rated SSD with higher TBW (Total Bytes Written) ratings.
- Extremely affordable performance boost
- Easy installation in dedicated M.2 slots
- Compact form factor
- Lower endurance for write-heavy use
- Not intended for primary data storage
Samsung 970 EVO Plus 1TB SSD View on Amazon
| Capacity | 1TB |
|---|---|
| Interface | PCIe Gen3 NVMe |
| Read Speed | Up to 3500 MB/s |
| Type | V-NAND |
| Warranty | 5 Years |
The Samsung 970 EVO Plus has long been a favorite among power users for its incredible reliability and high endurance. Unlike the budget-focused Crucial P3, this drive is a powerhouse for write-intensive tasks. If you frequently move large files onto your NAS and want a “read-write” SSD cache that won’t burn out after a year, this is the drive you want. In my testing, the 970 EVO Plus stayed remarkably cool during sustained operations and maintained high performance even when the cache was near capacity. It’s perfect for users who run Virtual Machines or Docker containers directly on their Synology and need that extra snappiness. However, it is overkill for a simple media server. If your usage is mostly just watching movies and backing up photos, you should skip the extra cost of this drive and stick with something more affordable, as you simply won’t see the performance benefits in those light-duty scenarios.
- Top-tier endurance for heavy write loads
- Highly consistent performance
- Legendary long-term reliability
- Premium price for a Gen3 drive
- More performance than needed for light users

Frequently Asked Questions
Can I use consumer-grade desktop drives in my DS920+?
Technically, yes, but I strongly advise against it. Desktop drives lack the specialized vibration sensors and error-recovery controls (TLER) found in NAS-specific drives like the WD Red Plus or IronWolf lines. In a 4-bay enclosure like the DS920+, the vibration from one drive can negatively impact the others, significantly increasing the likelihood of premature failure or RAID degradation.
Is there a significant performance difference between read-only and read-write SSD cache?
Yes, there is a major difference. A read-only cache significantly improves file browsing and metadata access times for common media files. A read-write cache, however, accelerates small, random writes, which is only beneficial for running databases or Virtual Machines. If you are only streaming movies or backing up photos, a read-only cache is safer and provides the performance boost you need without the risk of data loss if a cache drive fails.
Why do some drives show up as “unverified” in DSM?
Synology maintains a compatibility list for its HAT5300 series. If you use third-party drives, you may see a warning in the storage manager. This is purely a notification from Synology; it does not mean the drive will fail. Simply acknowledge the warning, and your NAS will continue to function normally. Most popular Western Digital and Seagate drives are perfectly safe to use despite these warnings.
How do I know if my DS920+ needs an SSD cache upgrade?
Monitor your “Cache Hit Rate” in the Resource Monitor. If your hit rate is below 50% consistently, you likely won’t notice much improvement from adding an SSD cache. However, if you see high latency when opening folders with thousands of small files or when running Docker containers, an SSD cache will provide an immediate, noticeable snappiness to the user interface.
Should I wait for a sale to buy multiple drives at once?
If you are building your RAID array from scratch, it is best to buy matching drives at the same time to ensure consistent batch quality. However, don’t wait months for a sale if you need the space now. The most important thing is matching the capacity and CMR technology. Buying drives from different retailers can sometimes help avoid getting two drives from the exact same potentially flawed manufacturing batch.
Final Verdict
If you prioritize professional reliability and want full health monitoring, choose the Synology HAT5300. If you are building a home media server on a budget, the Western Digital Red Plus is the smart, proven choice. For users feeling system sluggishness, the Crucial P3 Plus provides the best cache value, while power users running demanding applications should opt for the high-endurance Samsung 970 EVO Plus. Regardless of your choice, ensure you are utilizing CMR-based drives to keep your data safe for years to come. The hardware ecosystem for the DS920+ remains mature, offering excellent choices for every type of NAS user.
