More great work out of AVPreserve - thanks Chris for sharing. You may be interested to know that EVault/Seagate LTS2 cloud storage has now enabled its SHA256 features - doing the SHA256 down inside the storage tier on-demand (first release is for every 6 months at a container level, the subsequent releases planned will allow for customer to set the date for the fixity check). This is as well as MD5 that was supported all along. The feature is turned on now and being exposed through the UI within 30 days.

From: Chris Lacinak <[log in to unmask]> Date: Tue, August 05, 2014 7:08 am To: [log in to unmask] Hello Everyone, I wanted to point you to a paper we just published today exploring the difference in resource utilization (ie. time, processing cycles) between SHA256 and MD5. The paper, titled "What’s the Real Impact of SHA-256?", can be found at the following link along with the scripts used for testing and the raw data from the test results. http://www.avpreserve.com/avpsresources/papers-and-presentations/ All feedback and thoughts are welcome.
