You can replace the main hard disk and install the solid state. The specification of the hard disk that comes with the factory is: SATAII 2.5 inch 7 mm

Solid state hard disk runs faster than mechanical hard disk.

The number of memory slots to help you check the computer configuration is: 2, and the memory specification is: 1333Mhz DDR3. The maximum supporting capacity of a single memory slot is 4 G, and the maximum supporting memory capacity of the whole machine is 8 g.

Installation suggestion:

1. It is best to keep the same specifications and parameters as the standard, and there is not much requirement for the brand. It is recommended that you install the memory produced by regular manufacturers, such as Kingston and Samsung. In order to eliminate compatibility problems, it is recommended that you take the machine with you when you buy it, and add it after the actual test can be used normally.

2. If the memory with different models and specifications from the pre-installed memory is installed, it may reduce the frequency of use and may lead to incompatibility problems. If you want to install a memory that is different from the pre-installed model, you need to actually install it. If it can be recognized normally in the system, I suggest you buy it again.

3. In addition, it should be noted that the operating system will also have restrictions on memory identification: if it is a Windows 32-bit operating system, it can only identify the memory size of about 3G due to system restrictions. If it is necessary to identify more than 4G memory, it is recommended to replace the 64-bit operating system.
