Myth of the Day

All hard drives can be imaged at the same speed.
Category: All DME Myths
There are many variables that impact the speed at which a hard drive can be imaged. Some common variables include, the imaging tool used, the speed of the hard drive, presence or absence of bad sectors on the hard drive, and the type of drive connection. Most of these variables cannot be controlled by the examiner. For example, imaging the same 64 GB SATA SSD with one software tool took 36 minutes, a different tool took 33 minutes for the same drive and a hardware imager took 6 minutes.
