This page describes the differences between the various service tiers that Filestore offers and gives guidance on how to select between them.
Filestore offers Basic HDD, Basic SSD, and High Scale SSD service tiers. Each tier has different capacity options and performance levels to fit different use cases. The following table shows a comparison of the tiers:
|Specification||Basic HDD||Basic SSD||High Scale SSD|
|Scaling direction||Up only||Up only||Up and down|
|R/W Throughput (MB/s)1||100/100||1,200/350||3,000/660|
|Data recovery||Backups (manual only)||Backups (manual only)||None|
|Price per month for the minimum instance2||$204.80 ($0.20/GB)||$768.00 ($0.30/GB)||$18,432.00 ($0.30/GB)|
Selecting a tier
When selecting a tier for your Filestore instance, capacity is the
main determining factor on whether you should select Basic tier or High Scale
tier. If you don't anticipate that your instance will require more than 63.9
TB of storage, then select Basic tier. If you anticipate needing more than
that, select High Scale tier.
A second consideration when selecting a tier is performance. High Scale tier provides higher overall performance in multi-client scenarios. If your workloads are performance-critical and spread over multiple clients, you may still choose to deploy a High Scale tier instance for its performance benefits.
Once an Filestore instance is created, the tier cannot be changed. If you need to change tiers, you must create a new instance and copy the data from your original instance onto the new instance. We recommend selecting High Scale tier if there's a chance that you'll need the extra capacity in the future.
Quota for Filestore instances varies by region and tier. High Scale
and Basic instances each have their own quotas. High Scale SSD quota starts at
0. Before you can create a High Scale SSD instance, you must first make and be
approved for a High Scale SSD quota increase request.
