Has anyone tested with ECC memory? For non-ECC memory, it partitions off 1/8 of the installed RAM to do "virtual ECC". I was wondering if the parity calculation on every byte of memory was slowing the drive down. The benchmarks I've seen show it runs fast, but not as fast as it should for having 2 sata channels on the drive.

Normally ECC memory is a bit slower than regular desktop memory, but it shouldn't make a difference here. However, relieving the IO processor of the parity check could since it seems to be a bottleneck.

Is ICH10 good enough for RAID 0 on two of these (4 sata channels)? Intel RAID drivers use to allocate a chunk of memory for cache. Do they still do that? Hardware RAID seems like somewhat of a waste for 0, but a big 2GB cache like the higher end Areca's support might be nice. System RAM would be much faster and cheaper, but Vista is too stupid to use it on its own.
 
There's a jumper on the back to force the virtual ECC off which they say is not recommended. I may give that a try just to see.

I ordered a 2nd one so I could have enough space to run it as a boot drive. Currently my apps load fast, but grind to a halt (relatively) when they have to go to my Raptor for OS libraries like dx10.

Thx for the link. It was a good read.
