Virutal Machine disk type
I think it is a good idea to add a tooltip or text here (see below image) indicating that VM disk type = SSD will create SSD OS Disk and will be counted as a P10 Premium Disk which costs $19.71/month (I know there are different costs for different regions). Because, at first, I thought it is just a filter to display VM sizes that support SSD Premium Disk as Data Disks. I didn't think it will create SSD OS Disk and charge another P10 Disk. Thanks :)
I just wasted my credits because unintended creation of SSD OS Disk.
