We discuss Seagate Mach.2 Exos 2X14. Seagate is the firm with the quickest hard drives, and now they’ve renewed their management with a brand new 14TB mannequin that’s able to speeds as much as 524 MB / s. This velocity implies reaching virtually the restrict that connectivity permits SATA3.
Seagate reaches 524 MB / s: like an SSD
This velocity, nonetheless, is most sequential learn velocity. One of the predominant issues hard drives have is randomly studying and writing information. For instance, if we need to copy 1000’s of small information and they’re scattered on the platters, the velocity plummets to a couple MB / s. On an SSD, knowledge is accessible at the identical velocity wherever it’s, though if there are literally thousands of small information it additionally impacts velocity, though not as a lot as hard drives.
To obtain this velocity, Seagate has cheated a bit, since the Mach.2 Exos 2X14 is principally product of two 7 TB hard drives with two units of unbiased however joined and helium-sealed actuator arms in a 3.5-inch chassis. It additionally rotates to 7,200 RPM and has a 256 MB cache, though the random learn and write velocity are 304 and 384 IOPS, respectively, versus the tens of 1000’s or lots of of 1000’s that an SSD sometimes has.
The power consumption, having two hard drives inside, can also be considerably greater, with 7.2 W at relaxation and 13.5 W at most load. However, there’s a setting known as PowerBalance that enables to cut back the consumption to 12 W, though the efficiency drops by half in sequential reads and writes, and as much as 10% in random reads and writes. Therefore, it’s not splendid for large deployments, however it may be a very good possibility midway between SSDs and slower hard drives, not having to clone hard drives to SSD or simplifying the course of.
This know-how shall be the normal for years to return
Reaching excessive speeds on a hard drive is vital, though in knowledge facilities the place drives like this are used it would not matter a lot as a result of SSD drives are used as cache. Seagate claims it’s priced equally to equal 14TB hard drives sealed with helium, though they haven’t revealed the particular determine.
Seagate started the first experiments of the know-how Mach.2 in 2017 along with Microsoft. Little by little they had been opening as much as extra producers, and at the starting of the 12 months they introduced that they had been already ready to start out growing the distribution of those models in a large method, therefore they’ve lastly introduced them for any firm or knowledge heart past the that they’d agreed.
Going ahead, Seagate deliberate to start providing drives for 30, 40 and as much as 50 TB For the 12 months 2026 with this know-how, changing into a typical in knowledge facilities by then due to the mixture of applied sciences similar to HAMR.
