Hi Stuart and John -- Thank you for your comments. Yes, I do remember MS DOS Stacker etc. but I have never used virtual hard disks in MS Windows: I have asked about performance hit because I have found that when setting a "map network drive" share from VM to a host PC virtual harddisk it takes some time even to create and save via notepad.exe a small text file. During that time notepad.exe becomes "frozen". When you restart VM with "map network drive" share automatically remapped then such a "performance hit side effect" disappears... Anyway I'm going to try using virtual hard disks to keep the source files and test databases for my customers projects... Thank you. -- Shamil Mon 3 Dec 2012 13:36:06 от "Stuart McLachlan" <stuart at lexacorp.com.pg>: > > > > >I did some testing a while ago with Access and VirtualBox. > > There was no appreciable difference when writing and reading large test datasets between > Access running directly in Win 7 and running in a VirtualBox installation with a virtual HD. > > Certainly nothing a user would notice. > > Except in one instance where I created a new virtual machine and told it to create a > "dyanically allocated" disk rather "fixed size" - that really slowed down the initial writes :-) > > > -- > Stuart > > On 2 Dec 2012 at 20:28, jwcolby wrote: > > > Is the average Windows 7 desktop user going to notice the overhead of reading and writing to a > > virtual disk? > > > > John W.
