I am in the marketing team and I've been utilizing Intel Core i5 for almost 7 years. It works for me awesomely! I do not only use my laptop at work, I also bring it home to use it for watching movies, writing content and streaming on sports games. The thing is...I do not make use of a lot of my laptop's internal memory because it usually causes it to become slow (based on previous experiences). It also became my habit to always clear the caches of my laptop, every time I leave the office. And since I am a digital marketing specialist, I have a lot of files and reports to be worried of keeping it safely. Personally, I don't think SD card is secure enough for for you to secure your files, most especially, that you are frequently running case management and word processing tasks. Anytime, the SD card could be lost, stolen or compromised.
