Ahead-looking: The brand new Exos 2X18 laborious drives enhance on the already spectacular specs of the Exos 2X14 items. Utilizing the Mach.2 multi-actuator resolution, the 2X18 brings the common-or-garden magnetic storage know-how nearer to sequential knowledge charges solely seen in SATA SSD drives.
Who mentioned conventional magnetic laborious disks are lifeless? Definitely not Seagate, one of many few firms nonetheless making an attempt to innovate a know-how that dominated the storage world within the ages earlier than SSDs and NAND Flash reminiscence chips. The Fremont, California-based company is increasing its HDD providing for the enterprise market, introducing six new Mach.2 items. The HDDs are the quickest laborious disks presently out there.
Seagate describes Mach.2 as the primary multi-actuator HDD tech, an answer to extend efficiency by “enabling parallelism of information flows out and in of a single laborious drive.” First seen in motion with the Exos 2X14 product household, the Mach.2 know-how employs two actuators with impartial learn/write heads that may switch knowledge concurrently. The twin actuators function as if there have been two distinct 8TB or 9TB drives, whereas the host system sees simply the entire 16TB or 18TB unit.
Seagate’s new Exos 2X18 line of Mach.2 laborious drives improves the already spectacular specs of the Exos 2X14, bringing six new HDD fashions starting from 16 to 18 terabytes of CMR, 7200RPM quick storage to the terabyte-thirsty enterprise market. The brand new drives can be found in commonplace and self-encrypting (SED) fashions, utilizing both a conventional Serial ATA interface or a extra enterprise-oriented Serial Hooked up SCSI (SAS) interface.
Primarily based on the identical Helium Sealed drive design, all six drives embody 256 MB of multisegmented cache reminiscence. In addition they have the standard Seagate enterprise options equivalent to PowerChoice (to handle idle energy consumption), PowerBalance (to handle lively energy consumption), and Sizzling-Plug help.
Rated for two,500,000 MTBF (Imply Time Between Failures), Exos 2X18 drives are designed to work in busy, 24/7 enterprise environments with a 5-year restricted guarantee. In accordance with Seagate’s official specs, the SATA drives can maintain a most switch charge of 545 MBps. The SAS drives can go as much as 554 MBps in sequential studying/writing IO operations. Common power consumption is barely greater than conventional HDDs, going from 7.8/8W (SATA/SAS) whereas idle to 13.1/13.5W below heavy load.
