An essential piece of any system, the hard disk drive (HDD) stores and retrieves your data using one or more rotating disks coated in magnetic material. Rotation speed and storage size are essential factors to consider, and the Dell 4X1DR Hard Disk Drive (Western Digital WD9001BKH) does not skimp on either. The Dell 4X1DR Hard Drive sports a 6Gbps SAS interface in a 2.5″?(SFF) form factor, and up to 900GB of storage space. Its rotation speed of 10,000rpm guarantees efficient data retrieval, speeding up and smoothing out system operation.
