Why use SSD cache Synology?
A relatively small SSD cache can dramatically boost the data writing and reading speeds of large HDD volumes. In in-house tests, adding SSD cache to an all-HDD storage array boosted random write and read IOPS more than 15 times, and cut average latency by up to 93%.An SSD cache is a way of obtaining faster storage, reduced latency, and improved all-round NAS performance and access speeds. SSD caching is the perfect solution for IOPS-demanding applications such as virtualization and databases, significantly improving the quality of workflow.This means the life of these drives are around 6 months.

What is the maximum SSD cache in Synology : 930 GB

For Synology NAS models using an Alpine CPU, the maximum cache size is 930 GB. For other Synology NAS models, the maximum cache size is 127 TB.

Is SSD cache useful

Improved performance

Copying the most accessed data (hot spot) to SSD Cache allows for more efficient hard disk operation, reduced latency, and accelerated read and write speeds. Using high performance SSDs to cache data from HDD volumes improves I/O performance and response times.

Will SSD make my NAS faster : A NAS does not necessarily need to use an SSD, but using an SSD can increase the read and write speeds of a NAS. SSDs offer faster read and write speeds and higher endurance than traditional hard disk drives (HDDs).

NVMe SSDs shouldn't be the first consideration for use in NAS drives because they aren't supported as primary storage devices. They do, however, offer general device performance benefits since they're used only as cache drives, acting a little like extra RAM.

If an SSD has a cache, when data needs to be read or written, the SSD will first try to obtain the data from the cache, which will improve the read and write performance and the response speed. It will also reduce the chip wear and increase the SSD service life.

How long will a SSD last in a NAS

Typically, modern SSDs can last several years, often 5-10 years or more with typical use.Theoretically, bigger is better, but in practical applications, if the SLC Cache is larger, it will take up more space on the SSD. In general, SSD vendors may make 1-1.5 GB cache on a 120-128 GB SSD and a 1 TB SSD may have a cache nearly 100 GB.Estimate SSD cache size by expected volume size

If you are planning your storage capacity and haven't created any volumes yet, you can estimate the minimum size of an SSD cache based on the volume size you plan to create. We recommend setting the minimum size of an SSD cache to at least 2.5% of the volume size.

DRAM SSDs incorporate a DRAM chip in their design, serving as a cache for frequently accessed data to enhance overall performance. The inclusion of DRAM enables quicker random read and write operations, particularly in scenarios involving intensive access patterns.

How much SSD cache is enough : The size of the SSD cache you choose depends on what you're doing, whether you're accessing large or small files, or whether you read and write data frequently. If you work a lot with small files, a smaller SSD cache might be enough.

What does SSD cache do : The SSD Cache feature is a controller-based solution that caches the most frequently accessed data ("hot" data) onto lower latency Solid State Drives (SSDs) to dynamically accelerate system performance. SSD Cache is used exclusively for host reads.

How long does SSD last in NAS

5-10 years

Typically, modern SSDs can last several years, often 5-10 years or more with typical use. It's best to check the manufacturer's specifications for more specific information on a particular SSD.
