General Description:

Barracuda drives are low cost, high performance, random access storagedevices designed to meet the needs of the original equipment manufacturer(OEM) marketplace.The Barracuda drive’s interface supports multiple initiators, disconnect/reconnect, self-configuring host software, and automatic features that re-lieve the host from knowing the physical characteristics of the targets (logicalblock addressing is used).The head and disc assembly (HDA) is environmentally sealed at the factory.Air circulates within the HDA through a non-replaceable filter to maintain acontamination-free HDA environment
