-The number of operations required to download a blob depends on which endpoint you use. If you download a blob from the Blob Service endpoint, you're billed the cost of a single _read_ operation. If you download a blob from the Data Lake Storage endpoint, you're billed for cost of multiple read operations because blobs must be downloaded in 4 MiB blocks. If you download blobs from the cool or cold tier, you're also charged a data retrieval per GiB downloaded.
