Extra Storage

I sure do put my poor computer through the ringer with all the pictures & videos I am constantly uploading. I try to keep them cleaned off & stored on disked. But I take so many photos, it can become overwhelming at times. But I have to make myself sit down & work on it, because if I don't the computer runs way too slow. I think I just need to buy memory to add extra space, for all the junk that I "just have to have" on my computer.
