I cant remember which, but I was looking into this about 1 year ago, and I found a product which was also limited to 4* 1gb ramsticks.

However, the drivebay was equipped with a battery unit, that could keep the data in the ram for up to 8 hours. Also, it has a small dummy pci-adapter, that draws power from your pci slot when the computer is just turned off, but still has a powercord from the wallsocket. (as pr pci standard 2.x, your pcislot can draw current to keep Wake-On-Lan or other similar things powered)

This means, that only if you have to move your pc to a new location and it takes greater time than 8 hours, will you have to reload the contents of the drive.

Ofc, having 2 of these, provided a newer model can take 4 * 4gb sticks or 8 * 2gb sticks, would be one FAST windows boot, and one equally FAST wow experience. Add some backupsoftware, and a normal platterbased harddrive, and do a frequent backup of those contents (Symantec Ghost springs to mind here) ..

That would be made of pure win.



Ofc, considering the speed of the Sata bus, and the relative cost of this setup, you might be better off just investing in an extra sata drive or more, and striping them. Searchtime is not nearly anywhere the same, but your data throughput is not far off.
