See the Drobo in Action, a wide coverage of various Drobo Performance Stats. Here are some stats collected with running Drobo as a direct attached storage and using some benchmarking tools to compile these results. All the performance stats are collected using different criteriaâ€™s that can affect the performance of the Drobo. Also used various connection methods including USB and Firewire to obtain these stats.

In this blog post we will cover the Vaulting technology related to the EMC Symmetrix V-Max and the DMX-4 technology. Vaulting is a key feature added on DMX-3 series of machines, which was further extended into the DMX-4â€™s and now the Symmetrix V-Max Systems. With power outages or major power fluctuations or other critical environmental conditions (temperature, water, fire and environmental hazards) in data centers, the vaulting technology saves all the data during the shutdown of the machine offering additional safety features with the customerâ€™s data in transit (channels, cache â€“ memory, etc).
Over the last few weeks I’ve been using Zumodrive, another cloud storage offering. This week Zumodrive released their iPhone client, which enables storage to be synchronised to an iPhone or iPod Touch device.
