@Shitij Bagga Apologies for delay in responding here! There won't be any performance issue when you mount on cloud and on-premises concurrently !
Azure Files offers fully managed file shares in the cloud that are accessible via the SMB and NFS file system protocols. This article discusses the scalability and performance targets for Azure Files and Azure File Sync
Additional information: Azcopy is the best tool in data transfer , Fast Data Transfer is a tool for fast upload of data into Azure – up to 4 terabytes per hour from a single client machine. It moves data from your premises to Blob Storage, to a clustered file system, or direct to an Azure VM. It can also move data between Azure regions.
The tool works by maximizing utilization of the network link. It efficiently uses all available bandwidth, even over long-distance links. On a 10 Gbps link, it reaches around 4 TB per hour, which makes it about 3 to 10 times faster than competing tools we’ve tested. On slower links, Fast Data Transfer typically achieves over 90% of the link’s theoretical maximum, while other tools may achieve substantially less.
For example, on a 250 Mbps link, the theoretical maximum throughput is about 100 GB per hour. Even with no other traffic on the link, other tools may achieve substantially less than that. In the same conditions (250 Mbps, with no competing traffic) Fast Data Transfer can be expected to transfer at least 90 GB per hour. (If there is competing traffic on the link, Fast Data Transfer will reduce its own throughput accordingly, in order to avoid disrupting your existing traffic.)
- This article provides an overview of some of the common Azure data transfer solutions. The article also links out to recommended options depending on the network bandwidth in your environment and the size of the data you intend to transfer.
