StorSimple Upload Calculator

Some time ago, I played around with the on-premise Azure StorSimple virtual appliance. Unfortunately, I happened to pick the new blob storage account in cool, RA-GRS mode. This happened to have a very expensive "per 10k write" cost and cost quite a bit of money when I uploaded 750 GiB of data.

Since then, we have seen Azure storage transaction costs come way down, especially on the v1 general purpose storage account type.

To help you get an estimate of storage and transaction costs for uploading bulk data into a StorSimple device, I've created a calculator here.

To begin, simply key in a GiB storage amount that you plan to upload, the per 10k write and per GB cost for your region and the calculator will give a guide to the expected transaction and storage cost to upload the data.





The calculator does not calculate transactions for day to day access, nor does it include cloud snapshot transactions or storage.

Be aware, the 512 KiB chunk size will reduce transaction costs, but will also significantly reduce deduplication. The Microsoft pricing page explains this.

This, version 1 of the calculator requires you to key in the per 10k writes and per GB cost for your chosen region and storage account type. It defaults to v1, LRS, North Europe, GBP costs as of the time of writing. I've purposely left out the currency symbol as it should work with most currencies as-is.

Hopefully with some additional time, I'll be able to add a pull-down box to choose storage account type and location and have it automatically enter those costs for you.
