Azure Files has always delivered secure, fully managed cloud file shares with a full range of data redundancy options. While customers love the simplicity of Azure Files and the hybrid capabilities of Azure File Sync, until now, scaling cloud file shares beyond 5 TiB required changing the paradigm for accessing data.
Today, we are excited to announce the preview of a larger and higher scale standard tier for Azure Files, now available to all Azure customers. This preview significantly improves your experience by increasing standard file shares’ capacity and performance limits. In select regions, standard file shares in general purpose accounts can support the following larger limits.
Azure Files standard storage scale limits
|Azure Files||Before (standard tier)||New (standard tier)|
|Capacity per share||5 TiB||100 TiB (20x increase)|
|Max IOPS per share||1,000 IOPS||10,000 IOPS (10x increase)|
|Max throughput per share||Up to 60 MiB/s||Up to 300 MiB/s (5x increase)|
Performance limits for a single file remain the same at 1 TiB, 1000 IOPS, and 60 MiB/s. Standard file shares are backed by hard disk drives. If your workload is latency sensitive, you should consider Azure Files premium tier, that is backed by solid-state drives. Visit Azure Files scale limits documentation to get more details.
Pricing and availability
There is no additional charge for enabling larger and increased scale for standard file shares on your storage accounts. Refer to the pricing page for further details.
We are introducing standard larger file shares in preview with support for locally redundant and zone redundant storages in select regions. We are quickly expanding the region coverage. We advise you to visit region availability documentation to get the latest information.

Frequently asked questions
Do larger file shares work with premium file shares?
We recently announced general availability (GA) of premium files with 100 TiB support. All premium regions support large file shares as a GA offering.
Does Azure File Sync support larger file shares?
Absolutely. Azure File Sync performance is a function of the number of objects, files and folders, in the sync scope, rather than of the capacity of the file share in the cloud. Our team is constantly making investments in improving the performance and scale of sync and cloud tiering. So, keep your Azure File Sync agent updated with the latest version and visit Azure File Sync scalability targets to keep informed of the latest scale.
What about larger file shares support for my existing standard shares?
We are working on upgrading existing storage accounts. After the existing accounts are upgraded, you will be able to opt-in your accounts into the larger file shares feature without any disruption to your existing workloads, including Azure File Sync. Stay up to date on the latest status through the region availability section of Azure Files documentation.
