Any real advantage under linux? Any benchmarks? (Score 1)

It seems to me that with Linux' hard disk buffering algorithms, this card wouldn't really make much difference from simply putting, say, 4 gigs onto the motherboard. All the useful files would simply be loaded into the buffer on the first load (yes, a once-off performance penalty, but no slower than copying the files from a normal hard disk to a solid state one), and then it would be faster even than RAM sitting way out there on the PCI bus.

On other OSes, perhaps it would be advantageous. But as to the suggestion that it could be used for virtual memory (this was on their Web page!), you have got to laugh. Does it make any sense to anyone? I mean why go through the kernel as a file operation, go through the PCI bus, get the stuff from RAM, bring it back and THEN turn it into a page; rather than using actual RAM?

Has anyone actually done benchmarks on the supposed applications of these things (say, webserving under Linux)? I could find no benchmarks on their web page. It seems to me that it might be 10 or 20 per cent faster, but given that the bottleneck is likely to be the network and not the machine (and besides, it would be better value to simply *upgrade* the machine), why bother?
