The size of the Virtual Memory in the computer is exactly how much space it takes up in the hard disk. In the hard disk, the virtual memory exists as the PAGEFILE.SYS. In order to fix this problem, Windows adopts “Virtual Memory” (also Virtual Storage) technology, which can take out some disk space to work as memory supporting programs running. So if the executed programs are too large or there are multiple programs running at the same time, the memory will run out quickly.
All programs running on the computer need to be executed in memory. Storage/memory is quite important for computers. So, the actual capacity of an SSD labeled as 120GB is just about 112GB. Therefore, when you find the SSD described capacity is not same as the actual one, you can convert the capacity according to following calculation method. But the hard disk manufacturers calculate the capacity on a one-step per 1000, that is to say, every 1000MB equals 1GB and every 1000GB equals 1TB, which leads to the “reduction” of SSD capacity.įor example, we buy an SSD advertised as 120GB, but it will only show about 112GB available for usage in the computer operating system. As a result, in the operating systems, the capacity is calculated on a one-step basis every 1024, so every 1024MB is 1GB, and every 1024GB is 1TB. It is well known that computers operate in binary (or base-2), which is a numeric system that only use two digits: 0 and 1. Make a conversion between vendor and OS capacity calculating method How to fix “SSD reporting wrong size” in Windows?Īfter figuring out possible reasons for SSD showing wrong space, it’s time to get a deeper understanding of each one and check the corresponding solutions. ▶The SSD drive is larger than 2TB but initialized to be MBR. ▶The Virtual Memory paging file is located on the SSD/HDD. ▶Vendor's capacity calculation is different from computer OS. So why the actual capacity does not match the described capacity? The following reasons can be accounted for the SSD not showing the correct size: However, some users find their just bought brand-new SSD drive showing wrong size for no reasons. Some users even transfer OS to SSD for a quick boot time. Thanks to the optimal reading&writing performance and low latency, SSD (solid-state drive) is becoming increasingly popular, and it has been a prior choice for computer users.
