Description of the Mach.2 Exos 2×14 drive appeared on the Seagate website: this is, as stated, the most productive hard drive today. In terms of information transfer rates, the device can compete with inexpensive SSD equipped with SATA 3.0 interface.
Mach.2 technology provides for the use of two independent magnetic head blocks. This design provides a significant increase in speed.
In fact, the Mach.2 Exos 2×14 combined two hard disk with a capacity of 7 TBs each, which in the amount gives 14 TB. And for the computer, this drive will look like two logical disks.
The device is made in a 3.5-inch format, and the spindle speed is 7,200 revolutions per minute. Helic technology is used.
A SAS interface that provides bandwidth up to 12 Gbps is used to connect. The declared established information transfer rate reaches 524 MB / s, which is just comparable to many SATA SSD. The average delay is 4.16 ms.
However, the use of two blocks of magnetic heads turns into increased power consumption. It is up to 7.2 watts during idle time and up to 13.5 W with heavy load.
Hard disk is focused primarily on data centers and cloud platforms. As long as the drive is only available to individual customers – he did not enter open sale.
