S3 Storage Classes

Archive

S3 Glacier Flexible Retrieval

$0.0036 / GB-month

Low-cost archival storage (formerly "Amazon Glacier") with retrieval times from minutes to hours depending on speed tier: Expedited, Standard, or Bulk.

  • Durability: 99.999999999%
  • Min. duration: 90 days
  • Best for: Backups and archives accessed a few times a year
Archive (Instant Access)

S3 Glacier Instant Retrieval

$0.0040 / GB-month

Archive-tier pricing with millisecond retrieval — costs more per GB than Glacier Flexible Retrieval or Deep Archive, but with no restore wait.

  • Durability: 99.999999999%
  • Min. duration: 90 days
  • Best for: Quarterly-accessed archives needing instant reads
Automatic Tiering

S3 Intelligent-Tiering

$0.0230 / GB-month

Monitors access patterns and automatically moves objects between Frequent, Infrequent, and Archive access tiers, with no retrieval fees and a small per-object monitoring charge.

  • Durability: 99.999999999%
  • Min. duration: None
  • Best for: Unpredictable or changing access patterns
Infrequent Access (Single-AZ)

S3 One Zone-IA

$0.0100 / GB-month

Same access profile as Standard-IA at a lower price, stored in a single Availability Zone rather than replicated across three — not resilient to AZ loss.

  • Durability: 99.999999999% (within one AZ)
  • Min. duration: 30 days
  • Best for: Easily recreatable data, secondary backup copies
Legacy

Reduced Redundancy (legacy)

$0.0240 / GB-month

A discontinued, lower-durability class AWS no longer recommends for new data — kept here for reference against existing workloads still on it.

  • Durability: 99.99%
  • Min. duration: None
  • Best for: Legacy workloads only — do not use for new data
General Purpose

S3 Standard

Default storage class for frequently accessed data — websites, content distribution, mobile and gaming applications, big data analytics.

  • Durability: 99.999999999%
  • Min. duration: None
  • Best for: Active data, frequent access
Infrequent Access

S3 Standard-IA

$0.0125 / GB-month

Lower per-GB storage cost than Standard for data accessed less often but needing millisecond access when it is. Carries a per-GB retrieval fee.

  • Durability: 99.999999999%
  • Min. duration: 30 days
  • Best for: Backups, disaster recovery, long-tail media
