Very simple upgrade for a Desktop PC, as long as it still has a SATA port available, and I'm not aware of any motherboards on the market that only have the accomodations for a single SATA Port.Also, nearly any modern Laptop could have its hardrive exchanged for this one. For many, it would be an upgrade, if only for the 3Gb/Second write speed. Western Digital are known for the reliability of their hard drives, and this model was built in the yesteryear, meaning it was built when things were still built somewhat better than they are today. Short of a static discharge from the sky, this here hardrive should keep running no matter what. All sectors come back good on a full diagnostic, and it has been "Boot & Nuked" for a full three cycles, meaning you aren't going to be liable for any data that someone else had ever stored on this hardrive.
