Here is our line up of the best and most affordable 120GB SSD upgrades for your laptops and desktops. We looked at 250GB, 500GB and 1TB SSD upgrades, it’s time we look at some of the cheapest, most affordable and popular SSDs in the market.
The only restriction on these SSDs is the storage size, they typically perform just as well as or slightly below its equivalent bigger sized siblings. At 120GB (128GB on some), the storage space while restricted is sufficient for most users. This is the size of some ultra portable laptops (also known as ultrabooks) in the market. For example, Apple’s MacBook Air and MacBook Pro starts with 128GB storage.
Given how cheap portable hard drive and USB flash storage are these days, as well as the availability of network attached storage in the office and at home, and not to forget the cloud, there is no real need for big storage space on your laptop.
And if you think 120GB is not enough and you are running low on space, a little house keeping is probably in order. If you still find 120GB small for your applications, there is always the 250GB or 500GB range, while not as cheap have also come down in price with some manufacturers offering budget alternatives.
If you are after a performance boost for your laptop and not looking to spend too much money then look no further.
