Synology SSD Cache employs a write-back cache approach in read-write cache to accelerate write operations. When the Synology NAS receives a write request, it stores the data on SSD cache blocks and then acknowledges the write operation to the application server.You must use expensive Synology-approved SSDs. Other NVMe SSDs only work for caching. No boot: The NVMe SSD can't be used for the boot volume that runs the operating system.If there are empty SSD slots on your Synology NAS, insert the unrecognized SSD to these slots and see if it will show up in Storage Manager. If the SSD is recognized, then the problem is with the SSD slot. If the SSD remains unrecognized, it might be faulty.
How to add SSD to Synology : Add SSDs to Expand the Cache Group Capacity
Go to Storage Manager > Storage.
Locate the cache group you want to expand. Click the ellipsis icon of its storage pool.
Select Manage SSD Cache Group > Add Drive.
Select at least one SSD to add to the cache group.
Confirm the settings and click Apply.
Is it worth putting SSD in NAS
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.
Why add NVMe to NAS : The data that is frequently or recently used on your Synology NAS can be accessed more quickly from the cache devices (M. 2 NVMe SSD) than from the larger, comparatively slower HDD/SSD devices. So basically, the NVMe SSDs borrow frequently or recently used data from primary HDDs/SATA SSDs and cache it.
When considering NAS HDD vs. SSD, one will find that while HDDs offer cost-effectiveness and larger capacities, SSDs provide superior performance and improved energy efficiency. The choice is dependent on specific storage needs and budget constraints. NVMe SSDs shouldn't be the first consideration for use in NAS drives because they aren't supported as primary storage devices.

Why is my SSD not detected
The BIOS will not detect a SSD if the data cable is damaged or the connection is incorrect. Serial ATA cables, in particular, can sometimes fall out of their connection. Be sure to check your SATA cables are tightly connected to the SATA port connection.If you need to use your NAS for high-speed data transfer or to work with large files, such as video and audio files or virtual machines, then using an SSD can greatly increase efficiency and speed.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. 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).
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.
What are the benefits of SSD cache in NAS : To put it simply, SSD caching improves the performance of your NAS by placing frequently accessed files onto a solid-state drive rather than a traditional hard drive. Since modern NAS systems can be configured to automatically 'learn' which files are accessed most often and cache them on the SSD.
Should I use SSD for data storage
You should use a solid state drive (SSD) when you need high speeds or deal with frequent read/writes on large data volume. SSDs are a better choice for data analytics or gaming workloads. 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.If your SSD not detected on the computer, try to plug it into another computer or use another SATA cable/port. If SSD is still not recognized, that indicates physical damage. For a broken SSD, the provided methods on this page won't help. You'll need to take your drive to a local disk repair center for help.
Why does BIOS not detect SSD : Outdated SSD firmware or missing drivers can cause detection problems. Keeping the SSD's firmware and drivers up to date is essential for proper functionality. Issues with other hardware components, such as a malfunctioning motherboard, faulty ports, or a defective PSU, can indirectly affect SSD detection.
