Seagate has reportedly started shipping the first 4 TB hard drives that are built on just four platters. This means that each platter has a density of 1 TB, which in combination with the 7,200 RPM speed and SATA3 interface, gives impressive performance for a hard drive.
The 4 TB drives that are on the horizon from Seagate will carry 64 MB of buffer, and in combination with its 7,200 RPM, it reaches read speeds as high as 146 MB/s. There is no word on its write speeds. Power consumption is also expected to be about 35 percent lower than that of the competition.
Now that 1 TB platters are becoming more common, it might not be long before manufacturers start shipping 5 TB drives with five platters of 1 TB.
When the drives will hit the shelves remains unknown, but it would be available for prices as low as $190 for the OEM version. The retail version that would include documentation and cables would cost $212. Seagate boasts that at these prices the drive will have the lowest cost/GB.
