Azure Blob Download Speed

I have a 137 GB blob .vhd file in my Azure Storage Container and am attempting to download it using the Azure portal. Why is the download performance so horrible? The browser is reporting >12 hours to download. Why is is so slow? Can anything be done to get it to download more quickly?

UPDATE Here is the AzCopy usage. I am copying the VM image from one resource group to another.

$srcImageURL = "https://vmimagevhds.blob.core.windows.net/spservers/"
$srcImageKey = "mykey=="

$destImageURL = "https://vmsdisktorage.blob.core.windows.net/vm-images"
$destImageKey = "myOtherKey=="

$imageFileName = 'SP2016ServerUnconfigured-osDisk.86ca1057-af4c-4920-9082-6ad155ed2734.vhd'

# Concatenate and AzCopy command
# Paste into the Azure 
$azCopyCmd = "AzCopy /Source:" + $srcImageURL + " /Dest:" + $destImageURL + " /SourceKey:" + $srcImageKey + " /DestKey:" + $destImageKey + " /s /pattern:" + $imageFileName

You can give a try to command line tool AzCopy or its core library Azure Storage Data Movement Library, which supports super fast transferring for blobs and the transferring can be paused & resumed.
