Will Disks Using Shingled Magnetic Recording Kill Tape for Cold Storage?

We previously reported on the rumored Seagate/eVault “cold storage” tech initiative seeking to use disks to supplant tape libraries.

Now come this analysis from The Register.

We know Facebook’s Open Compute Project has a cold storage vault configuration using shingled magnetic recording drives. Both Google (mail backup and more) and Amazon (Glacier) have tape vaults in their storage estate. Shingled drives could change that equation because, probably, the cost/GB of a 6TB shingled drive is a lot less that that of a 4TB drive and, over, say, 500,000 drives, that saving turns into a big sum of dollars.

What are shingled drives, you ask? This video from Seagate explains:

Seagate’s eVault Reportedly Developing New “Cold Storage” Tech to Compete with AWS Glacier

Very interesting, though somewhat speculative, article today in The Register that outlines some new technology that may make a disk-based competitor to Amazon’s Glacier as cheap but faster:

“EVault, according to our storage gossips, is going to use disks, next-generation slow and energy-efficient drives from parent Seagate, probably shingled magnetic recording drives, and thus be able to generate restores which are potentially faster than those achieved on Glacier.”

For details and full-on speculation, read the article.
