Digital Evidence Storage Ideas (Encase 7 Specific)

Post Posted: Thu Sep 26, 2013 7:33 am

Hello,

Just wondering how other members store and backup there digital evidence? Mainly E01 and E01X files.
Currently our plan was build a hardware raid setup which would be connected to 2 workstations via Infiniband 20GBPS ports.

Specs

RAID
8 x 2TB HDD Hardware RAID 6
Infiniband 2 x 20GB/s ports


Workstation 1 (ENCASE 7 PROCESSOR)
Evidence Cache- 2 x 512GB SSD'S Raid 0
Evidence Storage- 2 x 2TB HDD Raid 0
Infiniband 1x 20GB/s ports


Workstation 2 (ENCASE 7)
Infiniband 1 x 20GB/s port


We currently use the Tableau TD3 for evidence collection. The plan is to transfer the collected evidence from the TD3 to Workstation 1 for processing. Once processed the evidence would be packaged and transferred to the RAID. When the examiner is ready to examiner the evidence he/ she will access the evidence straight from the RAID. Once the case is closed the evidence and all associated files will be achieved to tape.

It is hoped that the RAID will produce around 600-800MB/s which the Infiniband should cope with easily. All HDD will be WD Black Drives.

I look forward to your thoughts and opinions

Regards

Jem

That seems incredibly robust. What kind of price range are you looking at to create a setup like that?

Hoping to build the whole setup for £2500-£3000 what's your thoughts?

My main thought is how many cases do you work on at once? If you're Police, 16TB will not get you far.

Hello thanks for your response, We are a small company and don't deal with to many case's per month. We are hoping 16TB (12TB RAID 6) will last us 8-12 months. The RAID can be expanded but its not a fun exercise. We hope to expand by 8 TB per year and replace all drives when their warranty's lapse every 5 years.

Once a case has closed with with archive to tape.
