Toshiba MG08 (MG08ACA16TE) 16TB HDD Review

Our review sample MG08ACA16TE didn't come in a retail box, which is hardly surprising as it's aimed at the enterprise segment. The MG08 is built on a standard 3.5in format with an enclosure thickness of 26.11mm. The drive has a spindle speed of 7,200rpm and 512MB of cache.

Alongside the Helium technology, the MG08 also employs TDMR (Two-Dimensional Magnetic Recording) technology. 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. Whereas conventional hard drives use a single reader and writer per 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.
