They are intended for use with Vista - and have recently been found to
be marginally more effective than a placebo (for Vista-performance).
The speed-gains are barely distinguishable from measurement-errors...
So, if the drives would help ZFS, it would be a big irony.

There are companies that manufacture "pure" SSDs (www.superssd.com,
www.soliddata.com) with battery-backup.
Unfortunately, the price-tag of these systems is still beyond reach for
normal customers.
