I guess not. Especially considering that some of these files will be useless tails from your big files, so there is nothing gained by having them in svdev instead of your Z2.
I would even argue that for your files, metadata only is the best setting, if you don’t want to repeat my mistakes 
My personal money quotes from @winnielinnie:
The 160KB file will have its first 128K block stored on HDD, while its second block, compressed down to 32KB, will be stored on the NVMe.
Retrieving metadata from a faster device makes sense, as the results are felt by the user: Browsing directories, apps scanning through many files, rsync crawling entire roots, and other typical usages.
Retrieving small blocks from a faster device doesn’t really make much sense. What is it about your 32KB text file, comprised of a single “small” block that makes it more important than a 96KB text file, comprised of a single “not small” block? The same can be said for binary files.
