A new invention in the world of IT services was announced recently by Toshiba. The company announced the launch of the world’s biggest twin platter hard drive for laptops at 750GB and 1TB. This newly designed and developed twin platter hard drive model fits well into the standard 9.5mm notebook drive, whereas the three platter 12.5mm drive does not fit in. Each of these drives spin faster than the WD’s Scorpio Blue drives at a rate of 5400rpm – 200 rpm. The WD’s Scorpio Blue Laptop is available in 640GB model for twin platters and 1TB for the three platter drives. Similarly, another company called Seagate has a Momentous 5400.7 twin platter drive of 640GB. However, comparatively Toshiba’s 2 platter drive is way better than these other systems.
Toshiba increased the areal density of its MK7559GSXP twin platter drive to 541.4GBit/sq in which is a minor increase from the previous Two platter 640BG drive’s 528.5GBit/sq in. Each of these newly designed drives uses the SATA II interface 3GB/s and has 8MB caches. It is also possible that WD brings out a new two platter 750GB Scorpio Blue 2.5 inch drive soon in the future. Also, Seagate can announce the launch of its two-platter Momentus 5400.8 model at 750GB in the coming few months time. The main reason behind these launches is the highly competitive IT support market which has a range of companies that always contest for the topmost position.
The company has a variety of 1.8 inch 320GB hard drives with an areal density of 516GBit/sq in. in two platters. Well, if Toshiba were to apply the 541.4GBit/sq in. technology, then there were chances that the capacities of the drive could have been raised to 340GB which is again, not much of an improvement. These drives launched by the company are energy efficient than its previous systems. The sampling of the drives will be designed in April for a trial by its users.
