Amazon Glacier may be using Blu-ray Disc as storage

ByJonathan Gross

Online storage that Amazon launched in 2012 "Amazon Glacier"Can save a large amount of data at a very cheap price. The storage medium does not have a chance to see it directly, but it may be a Blu - ray disc that is actually closer to us.

Amazon Glacier "$ 0.01 / GB per month with unlimited capacity"Uri, online storage that began offering services from August 2012 is. As of January 2017, this price has declined to $ 0.004 (about 0.5 yen).


Storage Mojo at storage information site predicts its identity as a Blu-ray disc in 2014.

First though it is a tape medium, environmental control is hard to do for long-term preservation, and Amazon does not deny that it is tape itself.

What can be considered next is a hard disk, especially a high recording densitySingle magnetic recording (SMR)Although it is costly consideration, it is out of the candidate.

Storage Mojo's attention here is that it usually takes 3-5 hours to retrieve data stored on Amazon Glacier. As long as you are just using HDD, this delay should not occur, so I thought that the robot is in charge of taking out the HDD. However, the HDD is vulnerable to shocks, so there are no robots that can handle HDD without giving a shock at this point, so it will be out of the candidates.

And Blu - ray disc (optical disc) is coming up. Since the new standard of Blu-ray disc · BDXL has appeared in 2010 and it can store data at 100 GB / 128 GB, Amazon took over 2 years from here to create its own custom "optical disk mass storage system" It is the idea that we developed, tested and service in 2012.

Although this is only Storage Mojo's forecast, Facebook will be in 2014Low cost & energy saving data center using 10,000 Blu-rayWe are announcing that the gigantic data center using optical disks is not a "unlikely story."


In addition, in 2016 Panasonic and Facebook collaborate to announce "freeze-ray" archive system for data centers using optical disks. According to Panasonic, it is said that using optical disks "It is possible to provide optimal cold storage that simultaneously protects the data integrity and cost reduction of the data center", so huge data like Facebook Even if Amazon Glacier, which requires a center, is using optical disks, it can be said that it has come to a very reasonable conclusion.
