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.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.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%.
What is the benefit of SSD cache in QNAP : Using the SSD cache technology, we can significantly improve the IOPS and I/O speed, and maintain a relatively low unit cost in order to satisfy the demand for utilized space and transmission speed. The SSD cache technology applies to a select number QNAP Turbo NAS models with a specific amount of memory required.
Is SSD good or bad for NAS
SSDs will also improve the performance of any maintenance tasks on the NAS drive itself. Anything that doesn't rely on the downloading or uploading of data is likely to benefit from an SSD. However, perhaps the biggest advantage of using SSDs instead of hard drives is they are significantly quieter.
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).
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.

Q: How long does a SSD last on a NAS The lifespan of an SSD in a NAS varies depending on factors like usage, type of SSD, and quality. Typically, modern SSDs can last several years, often 5-10 years or more with typical use.
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.
How big of cache for truenas : L2ARC Cache devices generally should not be used until you have maxed out your physical RAM. And one rule of thumb for size, is only 5 to 10 times the size of memory. Like 32GB of RAM would suggest a L2ARC Cache size of 160GB to 320GB.
Is 512 MB cache good : 512MB will improve the odds of a cache hit somewhat. How much effect this has will depend on the working set of your workload. The working set is the set of data that your application is using frequently enough for cache misses to cause significant delays.

Typically, modern SSDs can last several years, often 5-10 years or more with typical use.
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.The recommended size for the TrueNAS boot volume is 8 GB, but 16 or 32 GB (or a 120 GB 2.5" SATA SSD) provides room for more boot environments.
How much cache is recommended : A good base for the L1 cache is 64 KB per core. You can find this out by dividing the total amount by the number of cores in the CPU. A 256 KB L2 cache per core is perfectly acceptable, but gamers might benefit from 512 KB per core. And anything between 32 and 96 MB of L3 cache is perfectly fine for most purposes.
