I have already read the documentation about the fstorage, and from what I've seen, you can't erase only a block, fstorage only allows to delete entire pages

You are probably right, I was using pstorage because I think you cannot erase data in fstorage without erasing an entire page. In my application I have to update blocks individually and I thought pstorage is a better solution for me. Do you know if you can erase individual blocks in fstorage?

I think that I will use the fstorage library, as RK recommends, thanks also

Thank you, it seems to be easier to use, I've been reading the documentation of the pstorage and I think it's more complex. As I saw in the pstorage documentation that Nordic recommends use fstorage, but is experimental, I thought that wasn't a good idea use it in my code. Thank you again!

If you're using SDK 11 I would recommend using fstorage and fds instead of pstorage. They are newer, they are much more flexible and I don't think that pstorage is going to be developed much more, but they will be.

I am currently using pstorage in my code (SDK 11, S130, nrf51822) and I think it is working as expected. I cannot say if it is harming the hardware but it is doing what I want it to do. If you want I can add it here.

Thank you!

In the page where the pstorage is explained, there is an advertisement that says it's very old, I have read something about the pstorage in the forum, but i thinked that I couldn't use it because it's to old, I'll try to use it anyways, as I'll try it, I`ll tell you something

Maybe you can use pstorage? An example can be found here: devzone.nordicsemi.com/.../

However, it is very old so you might want to work on it a bit.
