Hi all I am in the process of pre-purchase for hardware and software ( almost certainly unraid ) I read this tech document - https://wiki.unraid.net/Cache_disk#:~:text=For the fastest possible speed,WD Black will do fine. With this clause "The final consideration in choosing a cache drive is to think about the amount of data you expect to pass through it. If you write ~10 GBs per day, then any drive 10 GB or larger will do (a 30 GB SSD may be a good fit in this case). If you write 100 GB in one day every few weeks, then you will want a cache drive that is larger than 100 GB. If you attempt a data transfer that is larger than the size of your cache drive, the transfer will fail." So my questions on cache size are basically, if i have a 32GB optane cache, will the transfer fail completely on my source client, if a single file is larger than 32GB ? Or, does the cache fail, and the transfer continues, albeit slower.. - The remote client will most likely be Windows. - The file might also be a torrent, so slow download. What about if i copy multiple files, from the same windows client, whereby the source files individually are all smaller than 32GB, however the total file batch ( i.e. xcopy /s or some other utility ) is much larger than 32GB... Will this bulk file transfer fail ? My network connection the the unraid server will be 1Gb/s at both ends. thanks kindly tim PS - i did search for "optane and cache" but nothing stood out to me as an answer.
