NoTouch Ramp Load technology
The recording head never touches the disk media, ensuring significantly less wear to the recording head and media as well as better drive protection in transit.

Low power consumption
State-of-the-art seeking algorithms and advanced power management features ensure low power consumption 

Tested for compatibility

Recording Technology
CMR: WD5000AZLX, WD5000AZRZ, WD10EZEX, WD10EZRZ, WD20EZRZ, WD30EZRZ, WD40EZRZ, WD80EAZZ

PMR, also known as conventional magnetic recording (CMR), works by aligning the poles of the magnetic elements, which represent bits of data, perpendicularly to the surface of the disk. Magnetic tracks are written side-by-side, without overlapping. SMR offers larger drive capacity than the traditional PMR because SMR technology achieves greater areal density.
