I think that this product is brilliant value for money. I needed an extra hard drive for my computer (I wanted to dual boot) as I didn't want to partition the one I already had. It works exactly as it should and looks like it's going to last. I can't find anything to fault with it at this point as it is working perfectly. Everything I wanted to know was on the page on Aria. They make it extremely easy to find the right parts for your computer and would definitely recommend them, because their warranties are brilliant too. Due to this there wasn't anything that I would've liked to have known before I bought it. It's a 250gb Western Digital hard drive and it works how it should, hope this helps :)
