Every tool has a learning curve; it's up to you to decide how much effort you want to put into it. When I wrote "benchmark them using your workload", I was thinking "install Debian, install your apps, run your apps, quantify what you can". If you're doing command-line stuff, the 'time' built-in for Bash can be very useful. But, it's also good to get a subjective feel for the system on the various media -- does it lag? Does it stutter/ freeze? Does it crash? I found that Debian and FreeBSD on SanDisk Ultra Fit 16 GB USB 3.0 flash drives was "good enough" for headless servers, but stuttered/ froze for interactive graphical desktop use (during disk I/O; especially writes). I have since migrated to used 16 GB SSD's. (Does your target hardware have a SATA port?) David
