It looks like a nice card. One thing I didn't get straight is if the cache is writethru or write back.
If the original posters problem is truly a burst write problem (and not linux caching or virtual memory overcommitment) then writeback is key.

If you are having a "write storm" or bursty writes that's burying performance, a scsi raid controler with writeback cache will greatly improve the situation, but I do believe they run around $1-2k. If it's write specific problem, the cache matters more than the striping, except to say that write specfic perf problems should avoid raid5
Actually, a single channel MegaRAID 320-1 (single channel ultra 320) is
only $421 at http://www.siliconmechanics.com/c248/u320-scsi.php It works
pretty well for me, having 6 months of a production server on one with
zero hickups and very good performance. They have a dual channel intel
card for only $503, but I'm not at all familiar with that card.
The top of the line megaraid is the 320-4, which is only $1240, which ain't bad for a four channel RAID controller.
Battery backed cache is an addon, but I think it's only about $80 or so.
