Seagate Exos Family
Seagate has begun producing premium hard disc drives for a long time. When it comes to information transmission, the Exos Mach.2 series of hard drives were really too good. The 18TB HDDs in the new New Exos 2X18 Family type are available in both SATA 6 Gbps and SAS 12 Gbps transfer speeds, making them a really exceptional offering. This new SATA iteration doubles the speed of its predecessor, supporting data transfer speeds of up to 6 gigabits per second (3 gigabits per second).
In terms of transfer rates, Seagate claims that the Exos 2X18/2X16 SATA can maintain up to 554 MBps and that the SAS versions can reach up to 545 MBps. Seagate's new Exos 2X16 and Exos 2X18 hard drives use 7.8W/8W at rest (SATA/SAS) and 13.5W/12.8W under severe loads (SATA/SAS), which is equivalent to first-generation Mach.2 HDDs.
Specs
The Mach.2 Family provides larger storage options, with 16TB and 18TB in addition to the standard 14TB. These HDDs are available in both SATA and SAS flavours, each with its own set of advantages and disadvantages. Although SATA drives perform better in terms of speed, SAS is the preferred storage format since it provides data encryption on the hard drive.
Magnetic recording at 7200 RPM spin speed and 256 MB of cache memory are used by the Dual Actuators. PowerChoice and PowerBalance are two additional controls for managing power usage. Helium has been pumped into the hard drive to protect its sensitive components from the vacuum.
Dual Actuator HDDs
Traditional hard drives used a single Actuator, which resulted in slower speeds and higher latency. Since 2017, Seagate has been trying out a technology called a Dual-actuator, and this year, they finally declared that they had succeeded. If your drive has a dual actuator, it implies that half of the recording heads will work together as a unit while the other half will work separately.
As a result, a hard drive's performance may be increased by a factor of two while its storage capacity remains the same relative to that of a single actuator drive. Assuming a latency of 4.16 milliseconds and random read/write IOPS of 304/560 after the installation of a dual-actuator, these hard disc drives will perform well.
Price And Availability
The business has been rather cryptic regarding its Dual-Actuator Hard Drives. There is currently no way to buy them. Since these modern hard drives are designed to function reliably around the clock in any climate, they are likely to cost more than their predecessors but will come with a longer guarantee period of five years instead of the usual three.
