Seagate’s Exos X14 is built on a standard 3.5in format but with a thickness of 26.11mm. The drive has a spindle speed of 7,200rpm and 256MB of cache.

 

The drive uses Helium technology which enables Seagate to use eight 1.75TB (areal density of 1058 GB/in2) CMR (Conventional Magnetic Recording) platters and 16 TDMR (Two-Dimensional Magnetic Recording) reading heads into the drive.

TDMR technology has come about because as the areal density of hard drive platters (discs) increases, tracks get ever narrower and as a result, magnetic inter-track interference (ITI) becomes problematic for the writer part of the drive head. TDMR uses two or more heads to read data from a single or even several nearby tracks at the same time to improve the signal-to-noise ratio delivered to the controller.
