16000 request/min = 266 requests/sec.
With a well-tuned Squid system I estimate that the disk I/O is less than 2000 IOPS
and the current SSDs should be able to cope with that.  So speed should not be an issue.

Why do you want to extend? Is it only to extend the disk cache capacity?

What is are specs of the current SSDs ?
It is worthwile to replace them with new SSDs with higher performance/capacity ?

The PDF points to a Windows-only based NAS !
