Now a RAM disk is when you use some RAM like a disk, but this isn't on the motherboard, so... how is it RAM? how does it connect?
see when they call this a RAM disk, they really mean it on the "DISK" part. It's SATA! It's a SATA drive you use like any other drive, it's just fast as hell because it's backed by RAM!
but doesn't RAM lose its contents when turned off?
YEP! that's why it has that big honking battery there, it keeps the RAM active when the PC is turned off.
I wonder how long that battery lasts for, also I guess wiping your data is easy... just unplug the battery, no way anyones gonna get at your data then.
