Storing Data For The Next 1000 Years

[Guest]

Santa Cruz (CA) – Have you ever thought how vulnerable your data may be through the simple fact that you may be storing your entire digital life on a single hard drive? On single drive can hold tens of thousands of pictures, thousands of music files, vid

"A 10 PB storage system could be built for about $4700"

That is 4.7$ per 1TB disk, without considering ANY redundancy or extra hardware to handle the wear spread...
I wish I knew where to buy such cheap 1TB drives...

Something is wrong with that sum, or the storage size.

Year, they probably mean a 10 terabyte system.

"throughput of 3.25 MB/s"???

Kind of slow... Is that a typo by any chance?

And how did they calculate 1400 years? I guess I'm not as imaginative to come up with it. It's about as fast as some old ATA33 drives that need defragging.
It's a good thought, we need some type of longer term storage but maybe they should look to new mediums (crystal, holographic, etc...)
Anything with moving parts will fail!

So in each group of 16 drives 6 of the drives are providing redundant parity stripes? So, for 10 petabytes you'd need 1639 1-Terabyte harddrives, each with their own dedicated ARM 9 proc, ethernet port, and NVRAM. So hardware costs for a single unit:
ARM 9 Board with SATA and Ethernet: $229
1 TB SATA Harddrive: $159
8GB SD Card NVRAM: $30
-------------------------
$418
To hit 10 PB 1639 units
--------------------------
$685,102.00 Dollars

You still need to add in network switches, and a chassis for all this, etc.
