the same as adding more RAM to your system. Is there a cheaper type of
RAM to make something in the 2GB to 16GB range? Older types of memory
modules seem to be going up in price per bit. Probably isn't true of
chips.
Current motherboards do 8GB of DDR2 (4x2G), which in dual-channel has
17GB/s (PC2-8500, 1066MHz, x2). That is more than the FSB of any cpu can
handle (even twice of the 16xPCIe)
For more, e.g. 16G+, there are server boards, which offer multiple cpu
sockets.. usually a required feature as you need to process that 16G of
data somewhere :)
My opinions:
- flash raid controller @ SATA2 or PCIe is interesting product if it
can handle 8-16G CF or USB sticks - in count of 4 to 8 (hw raid5,6,
hotswap) ... suitable for read intensive applications (mass-webhosting)
- memory based: what about to hack a motherboard to backup the main
memory and modify the system bios to preserve certain areas of it at
POST? Perhaps using linux bios it can even emulate a boot drive (or
preload the contents from a backup flash which was stored when power was
lost (from battery backup, as standalone ram based SSD do) ... suitable
for read/write intensive applications - database server - the solution
gives the fastest access and adds persistence by the flash,battery&bios.
