My google capabilities are failing me. I'm trying to find a comparison or review of speed differences between using an IDE or SCSI virtual disk in VMware Workstation. I could probably create a whole bunch of test scenarios, but it's easier to read about it. 
It's been recommended to use LSI or Buslogic SCSI over IDE when creating VM's, but I wanted to know why. Is there a speed difference? If so, what is it? Anyone have benchmarks on a given system comparing native vs emulated SCSI vs emulated IDE?
Long and short: I have an old Windows XP virtual I've kept up-to-date for years that started with a virtual IDE disk. I just ran Crystal DiskMark and it's about 1/4th the speed of my native HDD running on the host Windows 7 OS. I always knew an emulated disk would be slower, but not that much slower. Would converting it to SCSI make it faster?
