Software Defined Storage for Police Digital Evidence Management

Today’s digital forensic investigation units collect and process large amounts of data from body-worn cameras, crime scene photography and video, CCTV, facial recognition systems, smart phones, satellite data, license plate recognition and social media for each criminal justice system case file. All of these digital intake mediums generate large amounts of data that must be securely stored up to 100 years.

According to Police Chief Magazine, the Chula Vista, Calif. Police Department calculated that a single 30-minute video from a body worn camera alone took up almost 800 MB of storage space. If it equipped all of its 200 officers with cameras, the department projected that it would generate about 33 terabytes of data every year. This does not include metadata and the need for mirroring and data replication. A good rule of thumb is to allocate 4 times the amount of storage for every terrabye of video storage created in the field and ingested into the department IT system making the allocation of 12oTB of raw storage capacity for video generated by 200 officers a realistic target.

With data ingest rates increasing from 1TB to a projected 3TB+ per day per forensic crime scene unit, above and beyond body worn video, police departments are finding themselves “awash in digital data.” Small police departments may find themselves needing at least a half a petabyte of storage per year. Therefore, a reliable, secure storage solution is required to store and transport case file information to an encrypted centralized data storage facility that can easily scale to 10s or 100s of petabytes (1000 TBs). Many police departments are taking a hybrid approach to their storage needs by deploying storage systems both on-premesis as well as in the cloud with FBI Criminal Justice Information Services (CJIS) compliant vendors.

Given the high cost of transmitting large amounts of data over high-speed internet, police departments also require options for both physical data transfer of case files via mobile storage appliances as well as online transfer options for securely transferring data from police forensic office locations to offsite data retention facilities.

To help meet the needs of law enforcement agencies, OSNEXUS’ QuantaStor SDS Migration Edition, a secure petabyte-scale mobile data appliance, enables the secure transfer of large amounts of data without high network data transport costs and long data transfer time. Transferring forensic data with QuantaStor SDS Migration Edition is easy, secure, and cost effective.
