1. A high-level review of acquisition times for several
popular imaging tools

2. Background
There has been a lot of anecdotal
discussion regarding the relative
performance of various popular acquisition
tools. This document provides an overview
of some research currently being
undertaken. Once completed the full set of
detailed results will be published.

3. Tools Assessed
 EnCase Forensic Imager v7.06
 FTK Imager v3.1.2
 Adepto v2.1 (Helix3)
 EnCase LineN v6.12.0.21
 IXImager v3
 Raptor v2.5
 X-Ways v17.1

4. Speed Assessment Parameters
Each of the acquisition tools used in this research was placed
into one of two categories and measured for how quickly the tool
could acquire a 160GB virtual drive. The categories were:
 ‘Standalone’ – meaning the tool comes with its own bootable
environment
 ‘Dependant’ – meaning the tool itself is not part of a bootable
environment and requires a third-party write-blocking device
or bootable system.
Within each category the tools were tested in the same virtual
configuration. The default image type was selected together with
the fastest compression (if available).

10. Scalability Assessment
The tools were grouped by their ability to
accommodate being deployed in an
environment containing multiple source
devices. Two groups were identified:
 Unrestricted
 Restricted

11. Unrestricted tools
Tool Comment
IXImager Unlimited number of concurrent
acquisitions, one analysis licence
required
Raptor Unlimited number of concurrent
acquisitions, no licence required
EnCase LineN Unlimited number of concurrent
acquisitions, no licence required
Adepto Unlimited number of concurrent
acquisitions, no licence required

12. Restricted tools
Tool Comment
FTK Imager Requires write-blocker per concurrent
acquisition
EnCase Forensic Imager Requires write-blocker per concurrent
acquisition
X-Ways Requires write-blocker per concurrent
acquisition, requires dongle per
concurrent acquisition
