File system storage: you pay for your use of a file system based on its storage capacity measured in gigabyte-months (GB-Months).
Persistent file systems are ideal for longer-term storage and workloads. Data is replicated and file servers are replaced if they fail. Scratch file systems are ideal for temporary storage and shorter-term processing of data. Data is not replicated and does not persist if a file server fails.
SSD storage is optimized for latency-sensitive workloads or workloads requiring the highest levels of IOPS/throughput. HDD storage is optimized for throughput-focused workloads that aren’t latency-sensitive. For HDD-based file systems, the optional SSD cache improves performance by automatically placing your most frequently read data on SSD (the cache size is 20% of your file system size).
Backups: For backup storage, you pay for the amount of backup data stored, measured in gigabytes-months (GB-Months). Backups are incremental, which means only the changes after your most recent backup are saved, so you save on storage costs by not duplicating data.
Standard data transfer fees apply for transferring data between AWS Availability Zones (inter-AZ access).
Pricing
Different storage options are available based on the redundancy level and the level of throughput desired per TB of storage provisioned
Pricing example 1
Assume you have a scratch file system in the US East (N. Virginia) region, which has been provisioned with 4800 GB of storage capacity, and you spin up your file system for an 8-hour workload every day and then shut it down. You do this for 30 days (a month).
Total workload charge:
$0.14 GB-month / 30 / 24 = $0.000194/GB-hour
4800 GB x $0.000194/GB-hour x 8 hours x 30 days = $224
Total FSx for Lustre charge for the month: $224
Pricing example 2
Assume you have a persistent file system in the US East (N. Virginia) region, which has been provisioned with 4800 GB of storage capacity and per unit storage throughput of 100 MB/s/TiB, and you retain your file system for 30 days (a month) to execute your long-lived workload then shut it down.
Total workload charge:
$0.19 GB-month / 30 / 24 = $0.000264/GB-hour
4800 GB x $0.000264/GB-hour x 720 hours = $913
Total FSx for Lustre charge for the month: $913
