Hard Disk Emulation   31 January 2014, 03:36

This is my first posting here, and I did try to read through previous threads, but I still had two questions.

I was wondering if there were any compelling reasons to use the Hard Disk Emulation when setting up the RAM Disk, or is this more just for being able to see the RAM Disk in Disk Manager and/or running benchmark programs?

If the Hard Disk Emulation is turned on, is there any comparison data to show the speed impact vs. Hard Disk Emulation turned off?

Thanks.

Certain Windows services such as Volume Shadow Copy and Windows Backup only operate on a fully emulated HDD.

It's also possible to create partitions on those RAM disks and merge dynamic volumes in a RAID array.

Other than that, if you don't need the above to operate on a RAM disk, there's no need to use the HDD emulation.

As to how much slower it is, it really depends on what other software may be installed and OS version. If you'd like to run a quick test, try Crystal Disk Mark.

does the windows paging file need full hdd emulation? I was considering moving the windows paging file there. Wondering if there was anything special to consider.

No, it does not need the HDD emulation (although placing a page file on a RAM disk may be a bad idea; this article explains why).
