You have to screw up a storage system pretty good to have something other than the hard drives be the limiting factor.

  True but that doesn't imply you run at capacity all the time.

  this is generally true, but even small variations in other factors could propagate through a complex architecture to account for some of the differences presented here, especially over time. these data are still useful, but some of the caveats could be made more explicit. similarly, most drive benchmarks are 'artificial' in any number of ways and come with another set of caveats. since drive testing is already part of backblaze's process for putting drives into production, it could be especially interesting to compare and contrast performance data from testing with data from production use. i pick these nits because real-world storage performance info seems like a valuable public good (particularly for enterprise and enterprise-like usage of consumer drives), and i'm grateful to backblaze for offering it up.

  It's pretty easy to have software to be the limiting factor, such that you aren't taking full advantage of your throughput because the data's not there yet.
