HDD vs. SSHD vs. SSD
If you are low on storage because you have downloaded the latest 50+ GB videogames, and you are willing to update your hard drive system, and you go to the local shop, and you see all this weird letters: SSD, HDD, SSHD; but you do not have any clue about what they mean, then this post is for you.
First thing you should think about, is how much money are you willing to spend on your memory, and how much memory do you want to get. The best option for begginers would probably be somewhere around 500GB-1TB(1000GB)(1GB=1,000,000,000 bytes) which is a fair amount, but if you like downloading stuff a lot, you would probably watch out for 2TB-4TB, which clearly will result more expensive.
The real difference between those storages, is the time they will spend procesing certain actions you will perform on your PC. HDD is the cheapest, but it is also the slowest. SSHD is a hybryd between HDD and SDD, which is somewhere in the middle between price and capabilty. Finally SSD the fastest one, but it is also way more expensive, which is only good if you are willing to spend an extra 100 bucks on your customization, and it is also harder to install in some older cases that do not have SSD adaptation.
