Western Digital began shipping 10-TB hard drives filled with helium

HGST, a subsidiary of Western Digital, начала shipment hard drive models Ultrastar He10 . A feature of this drive is its size - 10 TB, helium-filled hull and the technology of magnetic recording (PMR). Inside hard drive - sealed area, filled with helium. This reduces turbulence during rotation of the plates, which reduces the load on the electric motor. Consequently, energy consumption is reduced by the disk, and when the device is heated not so much as analogs without helium.

Form Factor disk - 3, 5 inches. In addition to 10 terabyte model comes to the market, and an 8-terabyte. Moreover, there are variants of interfaces as Serial ATA (SATA) 6 Gb / s Serial Attached SCSI (SAS) 12 Gbit / s. Somewhat earlier, the company has already released archival disks of the same size, also filled with helium, it is Archive Ha10 a > technology SMR.



Disk size is 101, 6 × 147 × 26, 1 mm, weight - 660 grams. Buffer - 256 MB.

At helium drives have several advantages, among which are the following items:

- Hard disk drives package thinner. This means increasing the number of plates, and this in turn increases the capacity of the disc by approximately 26%. The weight of the "helium" hard drive with seven plates will be equal to the weight of the hard drive with the air inside and five plates;


- Lightweight wheels package will allow the hard drive to save energy to ensure the operation of the system. Thus, the company's specialists estimate savings of about 23%. When idle regular disk with five plates consumes about 7 watts. The same HDD with helium and seven plates will consume only 5 watts;

- The case of the HDD is sealed, which means that they can be used in immersion liquid cooling system.

New discs high performance, compared, for example, Archive Ha10 the same volume. Thus, the data read speed of up to 249 MB / s write speed - 225 MB / s. Time Search - 8, 0/8, 6 ms (read / write).

On disks are warranted for 5 years. Price models (8 TB / 10 TB) is $ 800-1000, respectively.
