Seagate is the first company to produce a 1TB two platters magnetic storage device. Seagate has introduced it’s first single platter 500GB and two platter 1TB hard disk drives to the world. Western Digital, Hitachi and Samsung all have three-platters 1TB hard drives.
To judge the performance level of a hard drive the easiest way is to look for the capacity of single platter design of the hard drive. Seagate’s new 3.5″ Barracuda 7200.12 has 1TB of data distributed between just two disks. These 500GB each platters have made it possible for Seagate to produce three-platters 1.5TB and four-platters 2TB in future, an unprecedented capacity. These new ‘cuda’s platters have world’s highest areal density of 329Gb/in²(Gigabit per square inch) compared to competing offerings, which allows them to hold up to 500GB data each platter.
These drives have fewer and denser platters than their counterparts which increase their performance, runs cooler, consume less power and improves reliability by reducing the points of failure. With less discs spinning, noise, heat and vibration level will typically decrease.
These drives spins at 7200RPM and will feature a Serial ATA-300(SATA 3.0GB) interface. Barracuda 7200.12 series will come in 1TB, 750GB and 500GB variants with cache of 32MB or 16MB of size. Its maximum sustained data rate has reached 160MB/s up from the 115MB/s of its previous 1TB generations.
These 3.5″ drives comes with three years of warranty coverage instead of five years. These new Barracuda 7200.12 disk drives support NCQ(Native Command Queuing), Power-up in Standby, 48-bit Addressing, S.M.A.R.T and other parameters of the mainstream range. A 500GB single platter Barracuda 7200.12 drive at around $57, is highly cost effective.
