Singular Expert Insight
The Ultrastar DC HA340 is Western Digital’s mainstream medium-capacity data-center line; at 12 TB it is a cost-effective, high-IOPS air-filled CMR drive for servers and storage arrays that need proven 24/7 durability. If you need much higher capacity per bay, the helium-sealed Ultrastar HC-series in our enterprise/server HDD range scales to 24 TB and beyond. For maximum IOPS, an enterprise SSD is the alternative.
