Information Dispersal Performance- December 28, 2007 Our focus for Dispersed Storage performance has been overall system performance which in a Dispersed Storage Network is driven by how quickly bytes travel up and down the client stack. This stack performance is basically what determines the speed of getting data on or off the dsNet, i.e. the speed of reads and writes. The sequence of events when going down the stack -- writing data is: 1. Source data integrity check 2. Compression 3. Encryption 4. Dispersal 5.

So mentioned this to Dennis Roberson and he connected me with this article at Toms Hardware which I found very enlightening. It turns out that increases in hard drive capacities have been keeping pace with Moores law (as observed) by doubling every 24...http://www.cleversafe.org/cs-weblog/2007/12/14/are-hard-drives-getting-slower |
