What disk type is more appropriate on Azure to replace my on-prem file server? Stardand or Premium?

I am about to replace my on-prem file server but I am not sure which type of disk I should choose from on Azure like Standard HDD or Premium SSD. I know Premium is more appropriate for workloads needing low latency and high performance i/o but considering my file server has only docs, spreadsheets, etc so I reckon that Standard HDD disks will do the job.

    @Edson Reis Welcome to Microsoft Q&A Platform, Thank you for posting your query here!

    You can choose Standard SSDs disk. I would recommend go for standard SSD in future it will be more useful and efficient .

    Standard SSD disks are standard disks backed by solid-state media, optimized as cost effective storage for workloads that need consistent performance at lower IOPS levels.


    Standard SSDs are designed to provide single-digit millisecond latencies and the IOPS and throughput up to the limits described in the preceding table 99% of the time. Actual IOPS and throughput may vary sometimes depending on the traffic patterns. Standard SSDs will provide more consistent performance than the HDD disks with the lower latency.

    For standard SSDs, each I/O operation less than or equal to 256 KiB of throughput is considered a single I/O operation. I/O operations larger than 256 KiB of throughput are considered multiple I/Os of size 256 KiB. These transactions incur a billable cost.

    What is the benefit of using Standard SSD disks instead of HDD?
    Standard SSD disks deliver better latency, consistency, availability, and reliability compared to HDD disks. Application workloads run a lot more smoothly on Standard SSD because of that. Note, Premium SSD disks are the recommended solution for most IO-intensive production workloads.
