Thanks so much for the advice. Not many give it so freely and in a timely manner …
I take your point about SSD drives. While I might not want to spring for multiple SSDs for storage now, could I expect a significant increase in NAS speed if I used the Ironwolf HDDs but chose a NAS that allowed SSD caching and if so, how large of a caching SSD is recommended?
You will achieve the best results with NVMe cache which is several times faster than regular SATA SSD (around 500MB/s). But also remember about the weakest link in the chain. Either it is CPU or LAN/ Thunderbolt, the overall speed will be limited to the slowest thing in the chain. The cheapest NAS with a cache option built-in is TS-351. A recommended cache would be around 200-500GB for photo editing.
The one and only job what cache does is copying frequently accessed data and storing this copy on SSD. Similar to Windows machine is copying data to RAM (system memory). This allows you to access data from faster media then comparably slow mechanical hard drives.
With Qnap, you can go step further and instead of having a copy of frequently used data on SSD, you can create a volume on SSD. You can enable tiered storage or use this fast volume for speed demanding tasks like video/photo editing or simply fast data transfers.
The best NAS with a cache/ volume option out there is Qnap 72XT series, featuring 10Gbit, Thunderbolt and NVMe M.2 slots.
Determining the SSD Cache and Monitoring SSD Cache Performance
The aggregate size of hot data and appropriate cache size can be determined with the help of Synology
DiskStation Manager’s SSD cache Advisor, where the number of unique files1
accessed in the last seven days
and their aggregate size will be displayed. For example, if the accessed file size is 200 GB daily, the
corresponding SSD Cache size should be 200 – 300 GB to ensure that all hot data can be accommodated.
Additionally, a mapping table will be created in the RAM module to track the SSD cache data. Therefore, RAM
size must be proportional to the size of SSD cache. Every 1 GB of SSD cache requires approximately 400 KB of
system memory. For Intel-based Synology NAS, only 1/4 of the pre-installed system memory can be used for
SSD cache. For Annapurna-based Synology NAS, the total size of SSD cache is limited to 1 TB.
Apart from SSD endurance, you should also consider the memory requirements of SSD caching. As an SSD cache requires a certain amount of system memory depending on the cache size, you may have to upgrade your memory if you want to mount a larger SSD cache. To maintain system stability, only 1/4 of the pre-installed system memory is allocated for SSD caching.
Since a 1GB SSD takes up approximately 416KB system memory (including expandable memory), a 2 X 128GB SSD read-only cache (total 256GB) requires at least 104MB memory, while a 2 X 128GB SSD read-write cache (total 128GB) consumes 52MB memory. It should be noted that a lack of memory will, therefore, limit the SSD cache size.
| CACHE CAPACITY | RAM REQUIREMENT |
|---|---|
| 512GB | ≧ 1GB |
| 1TB | ≧ 4GB |
| 2TB | ≧ 8GB |
| 4TB | ≧ 16GB |
