What is Synology SSD cache?
SSD caches can achieve better performance on Synology NAS by leveraging the advantages of SSDs. By storing frequently accessed data on an SSD cache, you can reduce I/O latency and improve system performance of your Synology NAS. Most Synology NAS models support SSD cache.
How do I add SSD cache to Synology?
SSD Cache Creation
- Check the Requirements and Limitations first.
- Install the SSDs in your Synology NAS.
- Go to the Storage page.
- Click Create > Create SSD Cache.
- Select a volume to mount the SSD cache.
- Select a cache mode for the SSD cache and click Next.
- Select a cache RAID type for the cache group and click Next.
Does Synology need SSD cache?
Using SSD cache is not recommended if the amount of frequently accessed data on your Synology NAS exceeds the maximum size of SSD cache or if an application is always under a high load.
What types of SSD cache does Synology offer?
Synology NAS allows you to choose from two SSD cache types: read-only cache and read-write cache. Both are useful in different applications.
Is an SSD cache worth it?
When you use an SSD cache, you benefit from the faster speed and better responsiveness of the SSD compared to the slower, traditional hard drive. In fact, the SSD can be 10 times faster than an HDD when it comes to specific tasks like small disk reads.
Is SSD caching worth it?
What is a good amount of cache for an SSD?
Details
| Volume Size | Minimum Size of SSD Cache |
|---|---|
| < 24 TB | 400 GB |
| 24 TB – 40 TB | 800 GB – 960 GB |
| 40 TB – 80 TB | 1.92 TB |
| > 80 TB | 3.84 TB |
Can I use an SSD as a cache drive?
There are several ways to use an SSD as a cache for your regular hard drive. This is not a new idea, and already has several implementations. The best implementation is by NVelo: Dataplex – It has read caching and optional write caching. Unfortunately, like ExpressCache it is available to OEMs only.
Does cache matter on NAS Drive?
Hard drive cache size does not matter anywhere since all modern operating systems do their own caching, and have MUCH more memory to use for it.
Is cache important on SSD?
SSD caching can also be a cost-effective alternative to storing data on top-tier flash storage. The objective of SSD write caching is to temporarily store data until slower persistent storage media has adequate resources to complete the write operation. The SSD write cache can boost overall system performance.
How much SSD cache do you need for NAS?
Should I get an SSD with a cache?
Do NVMe SSDs need cache?
SSD’s are NAND flash memory, they’re so fast they don’t need cache.
