Seagate Launches 500GB Drive For Tablets, World’s First 5TB For PC Coming Next Year

Browse This Page

Seagate on Monday launched a 500 GB Seagate Ultra Mobile hard drive designed for tablets. This new drive brings 7 times the storage capacity of a 64GB device and delivers the same performance as a Flash drive. The new 2.5-inch drive is 5 mm thin and weighs 3.3 ounces. As for capacity, the drive has 500GB space, which is enough for 1,00,000 photos and 1,25,000 songs. Some of the other specs on the drive include a SATA 6GB/s interface, 16MB cache and spin speed of 5400RPM.

The Seagate Ultra Mobile hard drive is optimized for tablet use and are able to manage shock, heat, vibration and gyroscopic motion. Also this drive will let users save data on the external hard drive using the company’s Mobile Enablement Kit which comes with its Dynamic Data Driver software tech. The idea is that Android tablet manufacturers will use the Seagate drive, along with the company’s Mobile Enablement Kit and caching software, to up the storage. The Mobile Enablement Kit includes a dynamic data driver and reference designs that would lower tablet costs since hard drives are cheaper than solid state versions.

World’s First 5TB HDD By Seagate

The world’s first 5TB drive, courtesy Seagate, is expected to show up next year. To explain you about hard drives, there’s something you need to know. Current hard drives rely on platters, and the capacity of individual platters is limited by the width of magnetic tracks, which are now around 75nm wide and can’t get much smaller without compromising data integrity. So a 1TB platter with making four-platters, goes not more 4TB hard drive.

But how the 5TB became possible is thanks to Shingled Magnetic Recording (SMR). This new technology allows hard drive makers to reduce the gap between each track, effectively saving up to 25 percent of platter space which would be wasted using current technology. However, it is not as straightforward as that. Since SMR doesn’t have the track gap, when it writes data it also affects adjacent tracks, destroying the data. Therefore the tracks are further broken down into bands and the drives basically have to rewrite the affected data.

So because of the SMR, the capacity of individual platters will be increased to 1.25TB, making four-platter 5TB drives possible.
