The Reduced Redundancy Storage Class Overview
Currently Amazon S3 provides two storage options: STANDARD and REDUCED_REDUNDANCY.
If you are storing your file with STANDARD storage option, Amazon S3 guarantes 99.999999999% durability and to sustain the concurrent loss of data in two facilities. If you are using REDUCED_REDUNDANCY, you may expect 99.99% durability and to sustain the loss of data in a single facility.
Why you may want to use Reduced Redundancy Storage? Pricing for Amazon S3 Reduced Redundancy Storage starts at only $0.10 per gigabyte per month and decreases as you store more data. So, you may want to reduce your costs by storing non-critical, reproducible data at lower levels of redundancy than the standard storage of Amazon S3

The Reduced Redundancy storage class was first introduced back in 2010 as a low-cost alternative to STADARD storage class and was designed for non-critical, reproducible data that you can store at lower levels of redundancy than the standard storage of Amazon S3.
But times have changed and now, as of Oct 2018, the price for the Reduced Redundancy storage class is actually higher than for the Standard storage class. And it is close to twice the cost of the S3 Infrequent Access storage class.
In fact you pay more to store objects under the Reduced Redundancy storage class than you will in Standard S3, while getting lower object durability.
As it follows from the AWS response to this publication, the Reduced Redundancy class is being phased out, and S3’s goal is to eventually deprecate the RRS storage class.
They advise to switch any data under the RRS storage class to either Standard or one of the archive classes.
