Hey Sccrooge, ACard's ANS-9010 Serial ATA RAM disk - The Tech Report - Page 1
It's not cheap and I dug around and found a couple of reviews and when I looked closely there doesn't sseem to be that much of an advantage over what you've got. I was quite surprised as it uses DDR2 RAM and that has to be about a squillion times quicker than any hard drive or SSD, it even has two SATA connectors so you can RAID it with just one drive.
As I said on the other thread though, it's the limitations of the onboard SATA controller. I don't regret paying for an Adaptec controller one bit, it's on the PCI Express bus (x4) and probably gives me about 50% more speed than when I simply plug the drives into the motherboard. It's worth having. The downside is it really does slow the boot time right down. It is an enterprise standard bit of kit for servers really, so it slowly counts the drives on POST, spinning them up one by one.
Anyway I spent quite some time looking at SSD drives as you've really got me quite errrrrrr excited with your results. (I am sad)
The price isn't that bad for the 32 gig ones, I know it means a lot of rebuilds but I kind of fancy buying them one by one and building up an array like you've got. I'd love to see what a 4 SSD RAID 0 could do on a really good controller, maybe an Adaptec with a x8 PCI Express interface. And no spin up time!
I mentioned putting the pagefile on an SSD, but in reality if you are using just SSDs for your system drive then your pagefile is already on them. It might be worth using one of the two other SSDs as a dedicated pagefile drive though as I reckon with three of them in a RAID 0 array you'll have pretty much saturated the SATA controller's bandwidth.
When you get them it HAS to be major playtime. Better buy some reinforced SATA cables so they don't melt!
