Hi,
I was wondering what cost advantage do SMR drive provide as compared to
normal CMR drive?
8TB SMR drive - $ 260
3TB CMR (Conventional Magnetic Recording drive) - $ 105
Is the 8TB SMR drive that you mentioned in another post on this mailing

You can also find these drives inside the STDT8000100 external
USB unit for a bit more at $300.

which any file system can use, but the file system has no mechanisms to
leverage or control the drives behavior hence they
'host aware' or 'host managed' SMR drives open the real possibilities for
