There are problems with 5 mm hard drives
There is a strong demand for HDD drives to reduce the price of Ultrabooks.
The most heavily weighted 2,5-inch format hard drives have a thickness of 7 mm, but engineers are already working hard to reduce this value to 5 mm. However, the situation is not simple. According to DigiTimes, slimmed-down HDDs are roughly around 500 GB, which is certainly not outstanding these days - especially for an Ultrabook. The "tight" capacity can be traced back to the limited space. The situation is further aggravated by the fact that 5 mm hard drives have shown stability problems during write/read operations, and moreover, the increasingly protracted development results in increasing costs, which will be reflected in the price tag of the finished products.

It can be seen that only Nostradamus could predict the appearance of "ultra-thin" hard drives, but the engineers are doing their best to deploy them as soon as possible. Until then, the manufacturers will be left with various hybrid solutions (mixture of SSD and HDD), which can meet Intel's strict requirements (boot time, return from sleep state, etc.) and are at reasonable prices.
