The 1.8-inch form factor hard drives on the market since 2003 and still allows for smaller volumes for mobile devices. After the official standard, the width is 54 mm, the maximum depth of 78.5 mm and the height of 8 mm. Therefore, these drives are suitable for smaller devices such as sub-notebooks (also known as a netbook) and to some extent portable media players. A big advantage is the high energy efficiency, which makes for noticeably longer battery life. Today, however, rarely applies to this standard, while still hard disks in this format are produced, since you are located in specific areas of the industry in action.

pros and cons of 1.8-inch hard drives.

The small size of the storage density is not particularly large, which already represent current hard drives with 320 GB maximum. With the rise of the SSD hard drives, the known producers started but also the production of their SSD hard drives in 1.8 inch format, as they offer a great way also to the often lower-performing and sub-notebooks used to more speed to help. Together with the positive energy efficiency could therefore be worth a 1.8-inch hard drive, especially if you want to store large amounts of data locally or need.

In addition to the difference in size is also not a simple SATA interface, but micro-SATA is used usually. The connection differs optically only in the slightly thinner design, which he should not be confused with mSATA. Power Technically, it is the normal version but very similar. There are also numerous cables and adapters that enable implementation of the various interfaces.

Some manufacturers, such as Hitachi are even gone over 1.8-inch drives to produce, which are mounted in a standard 2.5-inch hard drive bay. In this way it is possible for you to further increase the battery life of your laptop, if you want as opposed to forego the higher storage capacity.
