An SSD can be the sexiest in storage, but when it comes to cheap storage, the good old hard drive is still the best choice, especially when technology has more room to grow.
Just in time for the annual CES event, Seagate began distributing the twelfth generation of the Barracuda series of hard drives. These drives continue to rotate at 7200 rpm, but for the first time at Seagate with a capacity of 500 GB. Seagate has managed to increase the storage space of its plates, which minimizes the number of plates in the hard drive, and potentially the power consumption, temperature In addition, increasing storage density, also potentially, has a significant positive effect on drive performance.
On the hard drive there are tablets (actually disks) on which the information is stored. Plates with a coating of magnetic material that magnetically responds to the heads of writing and reading, thus the heads "write" on the plates the information. The writing-reading heads "fly" over the surfaces of the plates using an air bearing and maintain a distance of one nanometer (nanometer = one millionth of a millimeter) from the plates. The "head height" of the writing-reading heads is declining, because it directly affects the density of the storage space. The lower the altitude of the head, the more information can be written on the same plate.
Whereas in the previous generation of the Barracuda series (7200.11), Seagate used plates in volumes of 320-375 GB, now the new model, the 7200.12, increases the volume to 500 GB in a single plate. Seagate offers new drives with volumes up to one terabyte, which is less Of the maximum volume of 1.5 terabyte that the company introduced this year. Theoretically, the new plates enable Seagate to produce drives with a volume of 2 terabytes, Enabling her to keep her promise. There is no information about the power consumption of the drives, but it can be assumed to be at the level of similar drives with two plates from the previous series.
Seagate has announced that the new barracuda models will be offered in the capacity of 500, 750, GB and 1TB, with drives running from 16 to 32. Seagate also declares a continuous transfer rate of 160 megabytes per second, which is reasonable when it comes to a single-chip hard drive (the 500 GB model). The company has not yet disclosed the recommended retail prices of the drives, but we know that the warranty period will not exceed three years, As Seagate announced last month.
