The major difference between the two series is that the dsv4 series supports premium storage and premium storage caching while dv4 series does not.
Storage optimized vm series is ideal for.
For workloads which require high disk throughput and io consider selecting a storage optimized vm.

In a nutshell azure vm sizes consist of the following series.
Series description a series entry level economical vms for dev test d series general purpose compute f series compute optimized virtual machines g series memory and storage optimized virtual machines h series high.
Compute optimized compute optimized azure vm types offer a high cpu to memory ratio.
Ls series is only available in storage optimized vm sizes which offers up to 32 vcpus using intel xeon processor e5 v3 family.
The storage optimized vms in the l series are suitable for big data sql and nosql databases where io is paramount the largest size can give you 160 000 iops and 1600 mbps throughput.
The m series family of azure virtual machines are memory optimized and are ideal for heavy in memory workloads such as sap hana.
Storage optimized vm series is ideal for sql big data and nosql databases these are the l series of vm wherein input and output operations are key while retrieving and storing the data within the database.
The newest fsv2 series runs on hosts with intel xeon platinum 8168 cpus.
M series vms support both massive amounts of memory almost 4 tb along with the highest virtual cpu count up to 128 vcpus making them ideal for applications which also have a high cpu processing requirement.

For compute optimized vms with high cpu to memory balance the f series is the best option.
Compute optimized vm sizes have a high cpu to memory ratio.
160 000 iops and 1600 mbps throughput is the maximum of the size that a storage optimized vms can have.
Storage optimized vm sizes offer high disk throughput and io and are ideal for big data sql nosql databases data warehousing and large transactional databases.
Compute optimized virtual machine sizes.
The l series for storage optimizes workloads that require low latency such as nosql databases e g.
Storage optimized vm sizes provide high disk throughput and io and are ideal for big data sql and nosql databases.
In addition these vms offer a virtual cpu count of up to 128 vcpus on a single vm to enable high performance parallel processing.
We are excited to introduce a new series of virtual machine sizes.
The sheer number of azure virtual machine vm series and size options can be overwhelming to some azure practitioners.
Storage optimized virtual machine sizes.
Other types of vms are compute optimized and memory balanced vms.
