In general the x86 machines makes a faster NAS, but the RPIs draw a lot less power, but has a lot less performance.
Also you have to think about the power for the hard drive. RPIs kind of struggle with power delivery as it is, so if you are going to use an HDD, then it would be better to use one with its own power or a powered USB hub.
I use one of these, but it is pretty slow: http://www.cubietech.com/product-detail/cubieboard2/

I would gladly have, but I don't have x86 hardware that are old enough.
My oldest machine is a Core2-duo E6600 and it blows a PI Zero-1 right out of the water.
single threaded performance.
E6600: Total Measured: 280.11 ms
RPI400: Total Measured: 477.02 ms
Ryzen 3700x: Total Measured: 82.57 ms
RPI Zero-1:Total Measured: 3370.83 ms
With a quick compile test, the E6600 was also about double the performance of the RPI400, but the time is dominated by the final linking, which is single threaded.
E6600:
time make -j2
real 0m16.575s
user 0m15.600s
sys 0m1.816s
RPI400:
time make -j4
real 0m29.551s
user 0m27.457s
sys 0m4.081s
Ryzen 3700x:
time make -j16
real 0m3.113s
user 0m3.152s
sys 0m0.313s
RPI Zero-1:
time make
real 4m12.987s
user 3m15.891s
sys 0m13.104s

I regret giving away my Celeron 300A (clocked at 450) all those years ago. It would have been a nice comparison.
128 MB RAM
I1st gen Nvidia TNT GPU (16MB).
That machine was soo amazing when I got it, but the software soon started to go backwards.

Would have been nice to have a metal heatspreader to keep temps down, so you could essentially completely supplant the Pi 3+ in performance. But at the money you can't really complain.

While optimizations are always possible, the same applies to Arm (eg. this board runs 32-bit code, while 64-bit is 10-15% faster). And RISC-V has issues that cannot be worked around in the compiler (such as no conditional execution, load/store with indexing or writeback).

Is it 486 or better ?
