Currently working on RAMDisks Roundup and testing v2.
All further updates will be in the new thread.


Wasn't sure whether to post this in the storage or memory section, but I guess it makes most sense here.

For the past couple of years I been interested in and running a RAMDisk, but to my great frustration it has been really hard to find any kind of performance testing of RAMDisks. Most of what you find is superficial at best if not downright misleading.

So with the goal of coming up with some sort comprehensive testing of RAMDisk I thought I would start by finding as many RAMDisk software as I can and make a short evaluation of each of them. Then perhaps, as a community, will could come to some kind of consensus as to how to test them.

Keep in mind that many of those program can only create a Direct-IO Disk, which means benchmarks such as HDTune and HDTach will not be able to see those disks. Other benchmarks such as AS SSD often have erratic behavior when testing RAMDisks and will frequently crash. So as you can see finding good benchmark tools for testing RAMDisks might be problematic.

As far as performance testing goes, I intend to test as many variables as I can to see their impact on performance (if any), but I will limit my tests to only 64bit OS. I'm still finalizing my list but coming up with a testing method that's more than just running CrystalDiskMark on each RAMDisk and calling it a day is more pressing right now.

Downsides of RAMDisks should also be kept in mind. Since data on RAMDisks are volatile backup option are useful, unfortunately some program only offer to backup on shutdown (leaving you SOL in case of a crash) other offer even less options (if they have them at all). Backup options might not be useful to every usage pattern but it's never a bad thing to have them.
Also RAMDisks have an impact on CPU utilization, most of them will peg 1 core at 100% when operating at peak performance.

With all that said, if you notice any mistakes or oversight let me know and I will rectify them. Now let's move on to listing all the RAMDisks that I was able to run on Win7 64bit (in alphabetical order).

Wow, that took longer than expected biggrin.gif
Anyway, I'll start looking for some suitable benchmark tools, but I'd appreciate your feedback.
