(well, a software RAM drive can be mapped to a hard drive, so that it stuff its contents into it on power down, but with the downside that it all needs to be read back on boot.) So the only last advantage that a dedicated RAM drive has left is the fact it can have its own backup power, and doesn't empty on a reboot. (Not to mention servers where each CPU can take hundreds of GB.) So could just use some of that system memory as a RAM drive through the use of software. So if you need tons of bandwidth, and rewrite data all the time, then a RAM drive isn't a bad idea.īut most places where a RAM drive would make sense, one though might have a computer with support for 128 GB of system RAM at the minimum. RAM is also ridiculously fast, both in terms of bandwidth and latency, unlike hard drives. RAM doesn't really wear out over time, unlike Flash media that can only take a couple of thousand write cycles.

The main advantage of a RAM drive over an SSD or hard drive is for scratch disks and other temp and project drives. A RAM drive isn't a too stupid idea, even today.
