When just trying single threaded "put the finger in the air" measurements, the difference to SATA SSDs is not so big. Your mileage may vary. :-)

I read that NVMe SSDs can have in the ballpark of 1M IOPS.  I haven't 
seen that myself, but I don't run ideal circumstances usually.  Kioxia 
claims up to 385K IOPS on their previous get 12Gb/s SAS SSDs (over 500K 
IOPS on their new 24Gb/s).  I think that would likely be a tolerable hit 
for more capacity, but I guess I'd have to see what actual usage numbers 
end up being.
