Just to jump in.

Did you guys ever consider to shortstroke a larger sata disk?
I'm not familiar with this, but read a lot about it;

Since the drive cache gets larger on the bigger drives.
Bringing back a disk to roughly 25% of its capicity would give better cache ratio and less seektime.

So 2TB would become 500GB, but better then a normal 500GB SATA.
( Or in your case, swing it down to 750Gb )

Armand

Hi Bob,

Why do you consider that model a good drive?

Why do you like to use mirrors instead of something like RAID-Z2 / RAID-Z3?

And how many drives do you (recommend to) use within each mirror vdev?

Cheers,
Simon
