So iv recently started to put a little bit of work into my PC, and im currently looking to make the switch from my HDD to a SSD, but I'm not sure the size or different brands i should choose from.

Currently my PC is running with a 1TB HDD and im only using under 100GB

I'm not looking to buy a super amazing one, i don't do a ton of Computer gaming, and would only need 256GB or memory or 512 if the price was decent.

Would this one do the job i need?

Buy a 1tb ssd and clone device with clonezilla if your trying to concerve time/settings/files etc.
If files and reformatting is no issue then buy a small drive - if that's the case yes that works

Okay you you have to have the same amount or more storage on the new device. Good to know thank you

If cloning yes. Or you run the risk of data lse
