I just took a look at customer feedback on this drive here. 36% rate with
one star, which I would consider alarming. Take a look here, ordered from
lowest rating to highest rating. Note the recency of the comments and the
descriptions:
http://www.newegg.com/Product/ProductReview.aspx?Item=22-14
In general I agree completely with what you are saying. Making reliable large
capacity drives does appear to have become very difficult for the drive
manufacturers, judging by the many sad comments from drive buyers listed on
popular, highly-trafficked sales outlets' websites, like newegg.
And
be fairly easy
to (1) automate NAS snapshots and then (2) automate zfs sends of the
incremental differences between snapshots, but I don't want to spend the money
on electricity for that.
And when buying drives every few years, I always try to take advantage of
Moore's law.

This sounds like it will affect a lot of people since so many are using
SATA SSD for their log devices connected to SAS expanders.

That would suck worse.

Thanks for the comments. So ZFS alone cannot do what I'd like.

Hi Team,
We have a customer who wants to implement the following architecture:
- Solaris 10
- Sun Cluster 3.2
- Oracle RAC
The customer wants to use file system instead of raw partitions
Question:
- Is ZFS supported in Sun Cluster 3.2?
Sincerely,
SB

"zpool online" command does not work since no pool is available.
