This is the first time I've heard this expression.
So, you're telling me I shouldn't have bought all those WD Red drives for my ZFS machine?

I've been running ZFS in production and at home since July of 2006. Just resilvered a bad consumer drive with two bad blocks. All fixed now.

Hm, just makes one put ZFS everywhere! > The better the drives, the better the performance and data integrity with ZFS, but WD is really consumer grade hardware: Seagate ES or Hitachi enterprise drives have completely different firmware. Is the firmware the one that really matters here or is it about the quality of the hardware itself?
- Annatar 8y agoThe mechanical internals between a consumer grade and an enterprise drive from the same manufacturer are usually identical and might only differ in things like read and write cache sizes. Firmware is the only thing that matters, especially since that is the #1 source of the problems.
