wishlist - ultra 2/4/6 with sandybridge and hdmi
I want an ultra with an intel sandy bridge system and hdmi out. Sandy bridge has integrated video on the cpu that is actually pretty powerful. Why? An XBMC server.

Good point.
I did some googling and apparently there are people working on SSD caches for Linux. Facebook has released some open source code called FlashCache. Here's some documentation:
https://github.com/facebook/flashcache/ ... he-doc.txt
Interestingly they specifically mention handling the issue of backups:
It is possible to mark IOs issued by particular pids as noncacheable
via flashcache ioctls. If a process is about to scan a large table
sequentially (for a backup say), it can mark itself as non-cacheable.
Someone has run some database benchmarks using FlashCache and an Intel X-25M SSD and found a doubling of performance compared to having the RAID alone.
Another sign that this idea is becoming mainstream is reported by tomshardware which reports that the upcoming Z68 motherboards will have an SSD cache feature.
