Both the LaCie D2 Professional and the WD Easystore are high-quality external hard drives, and the decision of which one to purchase depends on your specific needs and preferences. The LaCie D2 Professional has a larger storage capacity and is designed for professional use, while the WD Easystore is designed for more general use and has a lower price point. If you have a specific use case in mind, such as backup or storage for large video or photo files, the LaCie D2 Professional may be a better choice. However, if you are just looking for a reliable external drive for general use, the WD Easystore would be a good option. Ultimately, both drives are good choices, so it comes down to personal preference and budget.
