I know you can stack ssd's in raid 0 until money runs out, but somewhere you'll hit a bottleneck. What is said bottleneck?

A fair guess would be the sata ports on the motherboard. How many drives might that scale to, on a recent intel board? I'd guess four or so.

Otherwise, if using a pci-e card, can you reasonably expect to saturate the lci-e bus?

Just thinking out loud really. Cheers
 
Here's a starting point...

Another advantage to M.2 is that you can use a very simple M.2 to PCI-E adapter to add one or more M.2 drives to your system. What we haven't touched on is the fact that an adapter card doesn't have to be limited to a single M.2 drive. While not available right now (that we can find at least) we completely expect someone to come out with a card that adapts four M.2 drives to a single PCI-E x16 slot. This would give you a ton of versatility since you could install four individual M.2 drives into a single motherboard slot or you could RAID the four drives together in a RAID0. Theoretically, this could allow for transfer speeds of up to 8GB/s which would almost match the performance of DDR3-1066 system RAM!

Thanks. I'm skeptical that mass storage could hit memory throughput, since memory has been connected directly to the cpu since the 775 days and I don't think PCI-E has an equivalent connection.

Sixteen channel PCI-E 3.0 seems to be roughly 8 gigabyte/s, so the Mushkin boards hitting 2 on an eight channel board is both very good and still plausible.

Slightly out of date DDR3 can push roughly 50gigabyte/s across four channels, so equivalence would seem to require more PCI-E channels than exist on a board. I'll take it as PCI-E providing the bottleneck for now.

Cheers
