    Does anybody really use SMR HDDs for anything but archiving? I have yet to hear fond words (that aren't marketing) about this technique.
    Stop TCPA, stupid software patents and corrupt politicians!

      They're not that much slower, at least for home users. Lots of random IOPS will kill the perf, but they can handle stuff like copying masses of files and extracting archives just fine. Assuming the OS buffers the I/O first.

        Good to see performance improvements as Linux is an industrial strength operating system used in the most demanding environments.

          Right, home users. Just don't dare try running something like a decent sized database, with lots of updates, or even a rather small number of VMs.

          SMR is fine to replace tape, optical discs, and basically anything that's highly read-biased. But it doesn't take many random writes before you're swamped.

            are SMR hard drives supposed to be used for anything but archiving?
