Non-Volatile Ramdisk

[Mylegit]

Is there a way to create a not volatile RAMdisk? Maybe a pcb that sits between the RAM and the DIMM slot with a battery that's connected to the power supply and is always on? Or a simpler motherboard feature? If not, why isn't there?

[AlwaysFSX]

Doesn't exist. There isn't the hardware in the ram to make the charge last.

There is no demand for such a feature. Ram uses so much power anyway that adding a battery would be pointless. May as well have a UPS.

UPS is the way to go

We actually have those there called SSDs.

Have you seen the speeds compared to SSDs of a RAMdisk?

There are some PCIe cards that come with batteries on board, on which DDR3 can be plugged in. Obviously, the speed is not quite there with RAM plugged in the mobo.

Ram is going to volatile no matter what.

 

You can have it setup so the ramdisk is always there. When you start the computer it will pull the information from an SSD or HDD and recreate the Ramdisk. When you shut down it will write those files back to the secondary drive. 

 

It has sort of the same effect of a non volatile ramdisk but your startup and shutdown period will be longer.

yeah yeah I know speeds aren't particularly comparable

but A: It was a joke

and B: You're kinda asking something difficult for "VOLATILE" flash storage to magically be non volatile...
