just an example... this arm device have USB3.0 and could plug external drivers with a fast speed http://gizmodo.com/5646025/marvells-15ghz-triple-core-arm-processor-can-play-140-hours-of-music-on-one-charge it´s a nice tool to implement since we don´t know what´s the quality of USB external drives, and we could use it as a home NAS server 2012/8/1 Roberto Spadim [off-list ref]:
well this will work on systems that have pci-express or pci slots for systems that don´t have slots like arm systems, i don´t know if this could work... maybe in some future we will have arm devices running NAS solutions, and a more secure system is nice... 2012/8/1 Stan Hoeppner [off-list ref]:quoted

Is silent data corruption like this simply to be expected when using cheap commodity hardware?When you pay less than 1/4th the price of one drive for the controller card directing all your drives, is it really necessary to ask this question? Two large pizzas cost more than a Syba/Rosewill/Koutech/etc SATA card. The pizza is consumed in one night, maybe some for breakfast. Would you trust a day worth of pizza with your RAID? With your data? One tank of gas for the average car today costs $50, the same as two of these SATA cards. The gas is gone in a week or two. You want the cards to run for 2-4 years. Your drives cost anywhere from $400-$1000, yet your controller maybe $50. Do I really need to say any more? Spend $150-250 on a decent SAS/SATA controller such as an LSI or Adaptec and you won't have to worry about this kind of thing. -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html-- Roberto Spadim Spadim Technology / SPAEmpresarial
