Hope Sun allows me to buy these cards separately. ZFS administrators have been clamoring for something like this ever since Neil Perrin wrote the alternate SLOG/ZIL update a year ago.
This will make ZFS smoke every other filesystem on the market, and will Solaris (and ZFS) as the clear leader in the Unix market.
I just *really* hope the cards work in my HP Proliant servers otherwise we'll probably end up switching to Sun hardware.

SSD worth the $$$
Solid state disks are definitely worth the money, but from experience with them, I somewhat doubt their "30k read IOPS" rate, 20k might be a more realistic number. Sustained sequential writes (beyond cache) also start approaching or going below HDD speeds, but having no (very little) overhead of random sector writes quickly can overcome this limitation.
Unless Sun shots itself in the foot (with a BFG), you should be able to get their drives as standard SAS drives in 2.5" format. This also means that a standard SSD drive (available now) will work in any server/blade with a 2.5" SAS/SATA bay.
The best use, as described, is for FS journal logs and database scratch space. ZFS is not the only FS that can take advantage of this.
Oracle and SSD
Installing Oracle disk I/O intensive operations like 1) redo log files, 2) indices, 3) temp tablespaces (used in joins,order by statements and index creation) operations and undo tablespaces - should improve performance significantly
RAID'd Flash
Although this is a great start, Texas Memory Systems has a 2TB RAID'd flash system. Although I'm not personally using it, it seems to get around the problems associated with SUN's type of SSD.
