Best SSD for Synology NAS to Get in 2024

Choosing a solid-state drive (SSD) for your computer is quite simple – all you have to do is pick the one that’s supported by your computer, comes with the capacity you need, has decent data transfer speeds, and is reasonably priced.

However, this process becomes more complicated when choosing a Synology NAS SSD drive. While you can also use typical SSDs for desktops inside NAS enclosures, they’re not exactly designed for such tasks. That’s where specifically-designed SSDs come into play. Namely, they have features specifically designed for a NAS system, which makes them an excellent choice.

It’s important to mention there are plenty of great SSD options for Synology, but some tools are simply better than others. Synology makes its own SSDs and HDDs too. If you’re not sure which SSD you should go with, this article is perfect for you. Here, we take a closer look at the 6 best SSD for Synology NAS you can get in 2023.

How We Picked the Best SSD for Synology NAS

The market is filled with numerous outstanding SSD solutions, so choosing the best SSD for Synology NAS isn’t easy. That’s why we used different criteria to examine the features of available tools and determine which ones will take the lead in 2023.

SSD capacity is the most important feature, so consider it carefully. SSD caches have two system memory requirements that mostly depend on your DSM version:

  • DSM 6.2 or lower: every GB of SSD cache requires 416 KB of system memory.
  • DSM 7.0 or higher: every GB of SSD cache requires 400 KB of system memory.

When it comes to capacity, all add-on system memory is used to support the SSD cache. However, users can’t make their SSD cache bigger than their system memory allows.

Data Transfer Speed

Another crucial feature is the data transfer speed, and SSDs are known to have faster read and write speeds, at least when compared to HDDs. They can also access large files quite quickly, which makes the entire process of data transfer significantly faster.

Furthermore, SSDs don’t need to spin up as HDDs do, so they’re visibly more responsive and provide improved load performance. With faster boot times and overall better performance, SSDs are quickly becoming the go-to choice of many Synology NAS users.

Mechanical HDDs come at lower prices than SSDs. Nevertheless, they’re slow and loud. Moreover, these drives have running motors that vibrate and can potentially cause failure, which is why many people prefer SSDs.

Although SSDs come at a slightly higher price point, they don’t come with the abovementioned issues. SSDs are faster and quieter because they don’t have any spinning or moving parts. As such, they produce less audible noise.

Another vital feature is reduced power consumption. The lack of moving parts also results in SSDs needing less power than HDDs.


The best SSD drives must be secure and robust. These drives hold some of the most valuable information, and someone gaining unauthorized access to the content of these drives can harm the drive owner’s security.

With cyberattacks on the rise and cybercriminal activity reaching new highs, all tools and solutions need to implement the necessary features to maintain or even upgrade their safety features. With that in mind, it’s important to assess the security of SSDs and ensure they protect the owner properly.


SSDs are far more reliable than HDDs simply because they don’t have any moving parts. That allows them to be more shock-resistant and handle heat much better. Many SSDs even have power loss protection built into the system, so no data is lost if there is a power outage. The SSD will remain in operation, and all data will be safely saved and stored.

Furthermore, the endurance of drives is another essential feature that contributes to the reliability of these devices. It represents the longevity of the warranty, and you can use it as an orientation for the expected lifetime of the SSD. While higher endurance doesn’t guarantee the SSD will last longer, it’s a good indicator of whether it will or won’t.

That’s why considering the expected lifetime or warranty is highly recommended for increased reliability.

Additional Tips for Choosing the Right SSD for Synology NAS

Even with these top six picks, choosing only one can take a lot of work. If you want to select the right SSD for Synology NAS and your needs, these additional tips will help you make the right call.

Protection Against Power Loss

Power outages are unpredictable and can cause data loss or corruption. Although they aren’t frequent, they can cause a lot of trouble when they occur. That’s why you need to protect your valuable data in these situations.

When choosing an SSD for Synology NAS, look for SSDs with power-loss protection features, such as capacitors or batteries, to ensure that the data is saved even when the power is gone. However, data loss can happen due to various reasons, installing a NAS data recovery software will help you recover deleted files from Synology NAS.

Consistent Performance

The performance of the SSD is crucial when it comes to data access. In fact, all tasks rely on the performance, so you should go with Synology SSD drives that are reliable and consistent.

Look for SSDs with consistent read and write speeds and sustained performance over time, especially for applications that require high-speed data access. That will ensure that the performance of the NAS remains steady and predictable.

Level of Endurance

Endurance is the ability of an SSD to withstand frequent intensive read/write cycles. Consider the level of endurance required based on the type of usage. For instance, an SSD with a higher endurance rating is needed if the NAS is used for business purposes. If you’re only using the NAS for individual needs, even SSDs with lower endurance should be okay.

Memory Requirements

The capacity of the SSD is critical when it comes to data storage. Determine the memory requirements based on the amount of data that needs to be stored. Ensure that the SSD has enough space to accommodate all the data without compromising the performance of the NAS.

Going with an SSD that doesn’t fulfill the memory requirements can lead to an extremely poor user experience, so you should avoid it at all costs.

SSD Cache Type

Some Synology NAS models allow the use of SSDs as a cache to speed up data access. Ensure that the SSD is compatible with the cache type supported by your NAS model. It will verify that the performance of the cache is optimized, resulting in faster data access.

Type of Application

The type of application running on the NAS is also an essential consideration when choosing an SSD. Heavy workloads require high-endurance SSDs with a higher capacity to handle the increased workload. On the other hand, light usage can work with lower-endurance SSDs, which are generally more affordable.

That’s why it’s useful to have at least a vague idea of how you plan to use your SSD for Synology NAS.


Choosing an SSD for Synology NAS can be demanding, especially considering that there are so many options on the market. However, not all the available SSDs provide the same quality and features, so it’s important to go only with top-tier products. We have listed the top six SSDs for Synology NAS you can get in the article above, but it’s ultimately up to you to choose one that fits your needs.
