I got Western Digital 500GB 7200rmp hd. It's not terrible but it's slow as hell. I thought about Samsung f3 but i only got $65 budget for my new HD. Any recommendation? Keep in mind that I need at least 400gb of storage.
What do you mean slow? slow in what? If you think there is something wrong with your WD rma it. Getting a different hd wont increase your speeds a lot maybe a little unless you go raid, or buying an ssd.
