@Aroper: Like a cloud system within a cloud system. They are trying to fade the error correcting into the management system, just like a cloud, and together these disks represent the cloud.

@ASHU: I'm pretty sure these things have been standardized some years back. They are just dumbing down storage disks, nothing much. I think manufacturers won't have a problem dealing with this.

@Yalanand: I think it only stores, one time write discs. I don't think they'll be able to use it under a space management system unless MOSFETs are included.

@Gary_El: A shifting block data does have a security risk involved, if the data is being moved around in the same fashion again and again, hackers might successfully track it and hack into it. However I think Google has already thought about that in their implementation.

@Whoopty: I recently heard about a glass disk that stores your data for billions of years. It is readable and can have multiple writes on it. I wonder when these will be implemented into big data sets.

Re: Pretty intelligent

@Aroper-VEC       That is the first thing I thought of as well - A simple Raid.  We have to be careful to think just because Google mentions it - it has to be something innovative and new.  

There is nothing new about this concept, except Google appears to be pushing it.

Re: Pretty intelligent
True, RAID is an established concept that has been around forever, but I wonder if data shifting back and forth between cheaper HDD's migh open up a security hole for someone to exploit? But, anyway you look at at it, HDD's are a "sunset technology". Open up a computer these days, and they the last remaining complex, moving mechanical part

Re: Pretty intelligent
There is nothing new here. They're just adapting the premise behind distributed computing and applying it large scale for "cloud" storage. This is no different than RAID - which, literally, stands for a Redundant Array of INEXPENSIVE Disks. The problem with hard drives is growing capacity in scale and meeting IO demands. SSDs are no less error prone, or even more so in some instances, so they just want A LOT of hard drives to better balance the load but a lot of high-end hard drives would be very costly. They want to drive down the cost by shifting the error correcting focus away from the individual hard drives into management software. Though, this also isn't that dissimilar an approach to synapse computing in using a multitude of lesser expensive CPUs to distribute the workload with error correcting software managing the distribution and accounting for failed nodes.

Re: Pretty intelligent
Whoopty,

There is a lot of stuff here which is still very much open to conjecture at this point of time.

I for one would prefer to wait and watch how HDD manufacturers react to this Paper and what changes they make going ahead in their Design & Infrastructure.

Its not easy for these guys to change everything on the whims and fancies of Software Companies-Today Google wants something,Tommorow MSFT wants something else,then Salesforce???

Re: Pretty intelligent
I wonder if hard drives are really the solution for long term storage at this point though. NAND has come down in price so much in recent years that we may be looking at multiple terabyte SSDs in a few years rather than HDDs as storage.
