For those of you that use VirtualBox installation, how is the performance of your DSM4.2?
I have Windows 7, Virtualbox, Intel i3 3225 CPU, but 2GB of RAM. 4 x 2TB hard drive, + 1 WD Black for OS.
i have 1 x 250GB virtual disk image (VDK) on the WD Black drive as the first installation volume for my DSM4.2. Then I created 4 VMDK for each physocal disks and added them to the VirtualBox. These 4 x 2TB disks then got put into RAID5 in DSM4.2, and everything is working fine, but I can NOT exceed 20mb/s transfer rate to the DSM4.2 .
Over a gigbit connection, I have a real DS413 that can do 70mb/s. Does anyone have slow disk under VirtualBox?
